Computer Gives No Signal, Blank Screen

Question: Computer Gives No Signal, Blank Screen

So this past week I've had a bit of trouble with my computer. I had a hard drive fail on me to start and then this video problem started happening soon after I put in a new hard drive and installed Windows onto that. I have a Geforce8500GT and my motherboard is an AsusP5Ne-SLI running Windows XP Home.

This past week there have been random times where if I turn on the computer, I get nothing on my screen but I see that its still working, boots up and everything PLUS I hear Windows booting up in the background with the music going so I know that Windows is functional. There have been times that I have just been forced to do a hard reset and it seems to have solved the problem on its own and everythings back to normal. Tonight my luck doesn't seem to be as good as I've done a handful of hard resets and don't really want to do anymore risking other issues with my computer.I've tested the monitor on my netbook and it works fine. I've tried using the DVI port and no luck, I have NOT had the opportunity to try the video card in a new computer(plan to do that in the morning on a roommates computer). So, my question is, is my suspicion that the video card is going bad the real problem here or could it be an issue with my motherboard or Windows since I did have to reinstall Windows and put in a new hard drive.

Thanks in advance

Preferred Solution: Computer Gives No Signal, Blank Screen

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: Computer Gives No Signal, Blank Screen

Yer , Video card looks to be the issue , 1 suggestion remove the video card and firmly push it back in

Boot up and see if that solves the issue

My friend is using remote desktop to log into her work pc every once in awhile. The problem she is having is the morning after she logs in, she goes in to work and it has the normal login screen. When she hits ctrl alt del to login, the screen goes black and then says no signal. She claims that she has to power off the PC and then power it back on to get any response but today someone was on her PC and said they came back a half hour or so after it went black and just turned the monitor off and on and it came back. Any ideas as to what may be causing this or how to fix it? I've never seen this before.

Hey, I got my GT 240 in October of 2010. I haven't been very pleased with it, as I constantly have problems. However, I can't afford another, and usually I am able to fix it by spending several hours on Google every time it messes up (usually it somehow works itself out, though), so I just suck it up and deal until I can find a better, more reliable, and affordable card. I try contacting Nvidia and EVGA about this issue, but (sorry if I seem to just be complaining) neither of them seem to find this an important enough issue to even respond to my e-mail.

Anyway, onto the issue.

It seems every couple of months, whenever I get past the login screen for Windows, I get a blank screen, and my monitor loses signal from the video card. After fumbling around with it for several hours, usually I just take out the video card and resort to the onboard graphics, set the card aside for a few days, pop it back in, and voila, somehow that makes the video card work as normal. This time is different, however.

Here is a list of things that have been going wrong so far:
1) My sound keeps messing up. I know it is the video card, as when I use other ones, I have no problems with the sound. I know it doesn't make any sense, but it IS the video card. The sound keeps skipping/scratching whenever I play music.
2) Whenever I play a video, the video card freezes, and I have to restart the computer in order to do ANYTHING. It does not come out of this lock at all, unless I reboot the co... Read more

Bought a new custom built PC without an operating system. When it's plugged in I'm just getting no signal. I've got the operating system, I've got the graphics driver disc and I've got the motherboard disc but it's not recognising anything. How can I set up the OS / graphics if I can't see anything on the screen?This one's really bamboozled me but I know it's something really stupid and simple I should know. Thanks in advance

Answer:Blank Screen - Showing No Signal

how are you connected HDMI? try vga if on card or try connecting by motherboard onboard graphics (if fitted) first to set things up.

I help out at a local charity and one of their PCs was behaving strangely (Win XP home on a peer to peer network) amd I volunteered to assist (mistake!) The PC was attempting to send emails to Germany and the screen filled with Norton's AV scan block until disconnected from the internet.So - downloaded Spybot, deleted the few files found and ran the Norton scan - discovered trojan.pandex and was preparing to delete it and congratulate myself on solving the problem - when a message appeared briefly "Out of timing" or similar and screen blanked out.Now, any boot produces a black screen, no Post sound and can't reach safe mode - therefore a useless PC. Any suggestions for diagnosis and fix?

Answer:Blank screen and no post signal

Out of timingwill be a graphics/ monitor problem problem.How about resetting the BIOS to default by using the clear cmos jumper or by removing the cmos battery for a few minutes.Then see if it will reboot.pehaps an XP repair may then be in order.Repair XP by install over the top of existing system1. Boot the computer using the XP CD. You may need to change the boot order in the system BIOS so the CD boots before the hard drive.

I have an hp media center pc with windows vista. The screen went blank like this a few times , now it wont start up. Upon start up the fans run but there is no other noise and the screen fires up with a no signal message and goes dark. I cleaned out the computer as it was extremely dusty inside. And thats where it sits. Does anyone have any idea how to remedy this/ Thanx in advance for any info.
Reyy

Answer:Screen reads no signal and goes blank?

The "no signal" message on the monitor often means the graphics adapter (or graphics card if it's the removable type which sits in an expansion slot) has failed. If that's the case you need to replace it.

If it's an on-board graphics adapter (which isn't removable), you need to buy a graphics card and connect your monitor to that instead. Then boot into Windows and install it's driver.

Hello all!
I'm a kinda new PC tech (been dealing w/ PCs most of my life, but only been doing tech support the past couple years), and I've been working on an older couple's machine the past few days. The issue they've had is that, very occasionally, the PC will lose video; the monitor simply says "No signal". From what they've said, the PC is still running while this happens, though they have to turn it off for it to come back up. They said it even happens sometimes when they try to start the PC up; power comes on but no post appears on the screen, only the No Signal. From what I can guess, this indicates an issue in the hardware (my guesses were the mobo, cpu, gpu, or ram) but I have yet to even be able to duplicate the issue (and I've had the system in my shop for three days now). Memtest86+ revealed no errors in the memory, and I ran stress tests on the CPU and GPU (w/ Prime95 and MSI Kombuster, respectively), but everything seems to run fine (though the GPU idles at ~65C degrees, but I've read this isn't unheard of in an 8500GT, and even in the stress test, it didn't exceed 81C degrees). I opened the case up and made sure no components were loose or fried; the mobo is not touching the case, everything looks OK in there. I haven't ruled out overheating, though, because the room they keep it in is a TINY little workspace (more like a large walk-in closet w/ an outer window), and there's only about 3 fans in th...

So everything was fine before Windows 10 AU updates. The problem is that if I restart the computer it will I get a blank screen and my monitor(s) goes to sleep and loses signal and doesn't detect the video card so I don't see POST and just a black/blank screen. I'm pretty sure that it must have rebooted right to my login screen because I can tell my mouse/keyboard lighting up and my EVGA GTX 950 fan stop spinning after it reaches the login screen(it uses a EVGA Precision to control the fan).

But on a shut down and a cold boot up it's fine. Only on a RESTART that I will always get this symptom. But IF I shut down the computer and go into the BIOS and exit the BIOS it have the symptom once again like the going into the BIOS somehow make it no longer a COLD BOOT and it reads it as a RESTART.

What I have try and still doesn't work:
-use DDU(Display Driver Uninstaller) to remove Nvidia driver and using the Microsoft Basic Driver so Driver isn't the problem
-turn off FAST STARTUP(Fast Startup is disable in BIOS also)
-unplug and replug the monitor cable and power cable to the monitor
-try DVI and HDMI and still same symptom

With motherboard removed and power supply connected, monitor connected, ram in, CPU in, HD connected and Case Power Connector for front Push-Button "connected" the system acts like it's going to start but nothing shows up on the display and screen shows No Signal.
However, if I unplug the Case Power Connector for Push-button from the motherboard and start the system by shorting the two power pins on the motherboard ....then the system starts normally and the display works.
Does this indicate that I have a bad power connector, bad power button?  How do I solve this problem?  The power button is white when it does not start up.

I have HP desktop about 6 years old.  new hard drives and reinstalled windows in June.  It seemed OK then.  I upgraded RAM to Kingston VR 2x1gig (from oem 2x 256MB)  I think it was OK after that but at some point (I think it was weeks later) suddenly I heard beeping noise.  Beep for about 3 seconds then stop for about 5 then kept repeating.  Came to computer and found monitor blank (the light that changes from orange to green when there is signal was orange) and ctrl+alt+del does nothing.  It is completely unresponsive.  I hit power button and shut it off and when I restart it everything is fine.  sometimes will go a week without problems.  other times has recurred within few hours.  Could it be the new RAM?  other thought was that I had to slightly pull out graphic card to get RAM in.  Could something be wrong with this connection?  Should I reinstall graphic card?  put in old RAM? (I really like the 2 gig!)I leave computer on 24/7 because have USB TV tuner to tape shows.  I had computer set to turn off hard disks and go to standby and shut off monitor.  I just turned all these to "never"  (just have screen saver active) and now will wait to see if problem recurs.  Thoughts?

Answer:computer won't respond, monitor blank (no signal), and repeating beep

Its your ram....The beeps are because you haven't inserted your ram correctly , i suggest you to change the slots each stick is in , and make sure there in place correctly *you should here 2 clicks* ....

Anyways, he thinks it maybe a overheating problem since the inside of my computer was really dusty though I cleaned it out and it st has the same problem though I wasn't able to be super thorough as I didn't accidentally break anything.
I think the problem has to do with my power... My comp is like... It's Getting over powered since power cycling let's my computer have about an extra minute before the problem happens again and it sounds like my computer is working really hard.

This means that your monitor is not plugged into the Video card or the video card has failed.
Where do you plug your monitor into the computer? Do you have a separate video card? Or are you using the onboard VGA port (motherboard connection, see attached)? Make sure the connection is in tight.
If you have a separate video card, shut down the computer open the case and re-seat the Video card.

Hi,

I have a Samsung T220P which was used for not very, but was bought a long time ago when it was relatively new.
Anyway, this happens on two tested computers:
When the computer is turned on (Win 7), the screen shows some flashing thingy, and it always goes away 5 seconds afterwards and doesn't come back until the next reboot.
This problem isn't that important, I can live with it.

The main issue is this: after a few days of having the screen connected to a computer, the screen starts to switch signal sources (Analog and Digital) on its own. It's connected to DVI all the time, so I'm guessing it doesn't get a good digital signal, right? What can be done about it?

Thanks.

Hi all,

Whenever my chair knocks into the computer table, my computer will hang for about 15 seconds before shutting off. After that, it will start up again. If I'm lucky enough, the computer would start up fine. However, most of the time, it will seem like my computer is starting up (fans turning and lights blinking) but my computer screen doesn't receive any signal.

Once in a while, my computer will start up and shut down within 5 seconds with the screen receiving no signal. This cycle will continue non-stop until I turn off the power. I am guessing some parts came loose but I'm not sure if it is a hardware problem.

When my computer successfully reboots, a "Windows has recovered from an unexpected shutdown" message will be shown. I just received it 10 minutes earlier and this is what it shows.

I have two P4 computers that have died about a month apart. I thought power supplies were the problem so I replaced them but they still die at random times and some times at start up.

I get no warning except that one makes a series of chirping sounds either before, during, or after death. The other just dies silently.

I have run Western Digital hard drive diagnostics and both check ok on all tests. I have run Microsoft memory diagnostics and both check ok on all tests. I have reinstalled from scratch the op sys on both and it doesn't help.

When these die, they just stop and go to black screen indicating no signal. There are no blue screens or error codes of any kind. Both use on-board video. One is a Dell and the other is a Jetway system.

When they do get up and run, they run flawlessly. Sometimes they will go for hours and other times just a couple of minutes before death. Sometimes they just won't start up and it is always just a black screen stating no signal.

There is not fan or hard drive noise when they die. They just completely shut down as if you turned off the power.

Any ideas?

Answer:computer shuts down to black no signal screen

Try disconnecting everything (such as secondary hard drives, cd drives, usb devices, run on stick of ram etc.) except things you need.

If it still does it then id be blaming the psu or motherboard.

(actually I couldn't find the model I just know it hasan Intel chip on it) I then put it in and looked for a way to get a driver, that I couldn't find, then I disconnected the disk drive D:/ and put in my old HD (2GB) to get some files, which I did then i put the disk drive back and for ome reason i gave up on the modems took them out inspected them and then my comp wont send a display to the screen it just beeps in two different tones and then i have to unplug it to turn it off. I know i hooked everything up good and the screen works fine i even tried to reconnect the modems but it just beeps. PLEASE HELP ME!!!!! This is the only USABLE comp. I've had in a while!!!!!!!!!

Answer:Computer won't send signal to screen, just beeps

The modem might now be compatible with your operating system. More information on your modem would be useful. Things like how old it is, and what kind it is, etc. This information could help us make a proper diagnosis.[glb]Flame[/glb]

Hey I've been trying to trouble shoot this pc and so far I have the PC boot up CPU fans run, CD drive light blink, HDD spin etc but the screen shows it getting no signal. I have tried using a graphics card over the onboard video but the system doesn't have enough power to power the card. I think its a 250w psu. Have switched HDDs, switched ram, and cleared CMOS and still getting the same black screen as well as the lights on the keyboard flash for a second and the mouse light does not light u. Also switched between a working monitor and a tv with VGA input tried both VGA and DVI. Its an Acer M1201 AM1201

my parents have this problem with their computer.
at first when turned it on it was a black screen saying the computer was not shut down properly. my dad told me he just clicked start normally. then when it came back on it had this problem. when turning on the computer the monitor says no signal and then goes black. there are 2 beeps. the 1st seems like a short/medium beep and the 2nd one is a longer beep.
the computer is an HP.
what does this mean?
sometimes they use this computer for internet, but mostly my dad uses it for games. just simple games like casino.
 

Answer:computer problem. black screen no signal, beeping

I wanted to answer myself.
it looks like everything is good this morning.
I opened up the side of the computer to see if I could identify the RAM. the RAM are the 2 pieces that fit into slots? I undid the one pulled it out and put it back in and clipped it back in. don't know if that did anything.
I turned on the computer this morning and it gave me 2 options. either start normally or start with repair (recommended). so I started it with repair. it said it was attempting to repair and may restore the computer to an earlier version. after doing all that it looks like it repaired itself, because I was then able to start the computer again and everything looks the same as it was before.
I would still like to get some thoughts as to what could have happened? and is this something that seems to be totally fixed? or should I be watching for things to happen again?

I have a refurbished, out-of-warranty Gateway Profile 5 desktop. The screen is totally blank. I contacted Gateway. They are pretty confident the built-in display is defective. I was able to attach a second display which would also go blank just after the Windows XP Pro splash screen appeared. Using the 2nd display, I was able to access the bios. When I looked at the display setup, it was set to LCD & CRT. Not thinking, I changed the setting to LCD since I wasn't using a CRT. That disconnected my 2nd display, so I now have two totally blank screens. How can I re-access the 2nd display and then also avoid a blank screen when Windows XP boots up?

My computer was lagging and wasn't connecting to the internet properly, and then it froze so I shut it down. When I started it back up, the BIOS loaded but then went to a blank black screen with a mouse. I can move the mouse around. It won't load any further. I've tried all the safe modes and it does the same thing. And I tried cleaning all the dust off the computer. I've tried waiting at that screen for longer than 3 hours. It just stays there.

It's possible that it's a virus but I don't know. How can I solve this problem? Because I can't get into the computer to do a system restore. Please help, thank you!

I have an Acer laptop which is about two years old. It started to run slowly and not very efficiently - then the screen started to go blank. Sometimes it goes blank when i am using it or when i am not. . I can see the computer is actually still processing so the whole computer does not shut down. I would be able to reboot and then the computer would be fine again. It started to do this more and more frequently until it was happening every couple of minutes and then my computer stopped booting up and loading software. I took my laptop to a recommended pc repair shot who reinstalled windows (unfortunately). It definitely was running much better and the screen stopped going blank. about 10 days later and the computer is running well still but the screen is starting to go blank again regularly - every 10-20 minutes! is this a virus/software/hardware??? thanks in advance for any help you are able to give me!

Answer:My computer screen keeps going blank even thought the computer is still running.

When the system is operating properly, set a System Restore point.

Then start out by updating all drivers and programs to the latest avalilable version.
Get all drivers from the PC Manufacturer's website, and get the updated programs from the program manufacturer's website. If you cannot find an update for a program older than 2 years, uninstall it.

Then visit Windows Update and get all updates
Then visit Windows Update and get Service Pack 1 (usually under Important Updates). Read these notes for installing SP1: Steps to follow before you install Windows 7 Service Pack 1 from the Microsoft Download Center
Then visit Windows Update and get any other available updates

I suggest starting all troubleshooting with the following diagnostic tests. They'll save you a lot of time and heartache if there is a hardware failure, and you'll have the disks on hand in case you need them in the future:

My computer screen is blank! I've been having some problems for the past week or two with my computer and then yesterday I went away from it for a while and when I came back it looked like the "blue screen of death" was up but there was no text, just a blank blue screen. Now whenever I start up nothing happens, it seems like everything works on the tower but there's just a blank screen, and the light on the moniter blinks like there's nothing to read.
The only recent hardware added was a wireless network a few weeks ago, but it seems to work fine. Recent problems include having to update my sound driver due to cpu restarting and now this, however I have had plenty of graphics card problems, but not for a while.

Built the computer a year ago and haven't had much problems after the first month or two. I'm running windows XP with an ATI Radeon 9800 Pro graphics card, and ECS socket 478 motherboard, and a 350W power supply, if you need any more info on specs let me know. I figured it's one of these 3 screwing up, so is there any way to test it or something I can do?

Hi,
I am a newbie on the site and I am in need of help. First time I responded to an old thread, so I hope I am doing this correctly this time.
We have a computer
AMD athlon 3000+ w/heatsink and fan
1 gig 2700 ddr333 ram with heatsinks over ram sticks
fx5200 128 mb
aopen mobo ak79d400vn
520 watt atx power supply

Problem: Tried to upgrade video card to 6600. Installed it and drivers and the computer starts up, fan is running, but nothing else a blank screen. Purchased off ebay mainly for processor and mobo to upgrade son's computer. Thought this would solve son's gaming problems ( BF2 should be hung for its greediness in cpu and video power) Now I am stuck.
Brought it to the repair shop and the guy said mobo fried and continued to tell me how bad the AMD cpu's are and tried to make me one for $$$$. Is the guy right?
Question: Is there a way to tell if the mobo is indeed blown and /or the cpu and can I change out the processor into another computer? I hate to think nothing can be salvaged on it.
I hope I haven't forgotten to say anything- Please forgive !
 

Answer:Computer screen blank

Brought it to the repair shop and the guy said mobo fried and continued to tell me how bad the AMD cpu's are and tried to make me one for $$$$. Is the guy right?Click to expand...

The guy is not right. Amd cpus are very good. For gaming they're tops, and for normal tasks they're no slouch either. My guess is he'd rather make the $$$$(big bucks), than make just a few $$(bucks) helping you fix your current one.

So, are you saying your system works with the 5200, but when you install the 6600, it doesn't work? If so, what sysptoms does it give? Lights, noises, fans, etc.

You could put the cpu into another pc with the same socket type(it also has to support the same cpu bus speed), to test it. Or you could swap the motherboard in your current pc and see if it works then, but both tasks are somewhat of a pain(the cpu will need thermal grease applied, and motherboards take a while to remove). You probably have a "socket A" amd cpu, since you say athlon, and not athlon64.

Also, your new card may be stressing your psu, if it's underpowered/faulty. You might want to list the brand and specs(amps per voltage rail), if you know the info.

Answer:blank computer screen

Any beeps when you switch it on? Any changes to the PC lately, crashes (or more frequent crashes), blue screens? Any strange noises from the unit when it's on? Possibilites include overheating (and subsequent damage to the CPU) or failing power supply. If the guarantee has run out you can take the side off the machine and see if loads of dust and fluff has collected inside and around the fans, that would point to overheating, but it sounds as if the damage has already been done on that front.

Can anyone help me with this?  On occasions (quite regularly) whilst I am typing my screen will suddenly go blank.  When it comes back on after a few seconds, the last few letters I typed are all transposed.  It is driving me crazy and slowing me down.  Any suggestions.  Windows XP.  Touch type, so not being able to see what is on the screen is not affecting my typing.  Working on a lap-top.  Someone, somewhere, must know what is causing this!It's so frustrating!  The transposed letters are not typing errors, the screen transposes the letters every time it goes blank.  It does the same whether I am online, sending e-mails or working with the word processor.  Help!!!

Answer:My computer screen going blank

Perhaps the monitor is faulty. Check if plug(s) are firmly inserted. I expect the letters get transposed because you have lost sight of what you are typing.

Hello,

I was just using my PC last night surfing the internet and doing some other things, but then my screen just went blank and it popped up saying no DVI connection or whatever. My PC still had power and all the fans were going and everything seemed like it had power. My pC has done this before but it was because my 8800GT got to hot and overheated. So I checked the cables and everything was tight so then I shut of my PC and waited a little while and turned it back on and got nothing not even the bios/bootup screen but everything had power and all my fans were running including the one on my 8800GT. Just nothing on my screen. So I turned it off again took off the side of my case and checked everything in there and everything was tight. So then I just left it off overnight and this morning tried again but still got nothing just power. So I decided to unplug everything and have only my memory and hard drive(s) plugged in and my Graphics card and tried just that and I still got nothing just power to my graphics card fan, PSU, and the CPU/heatsink fan. So I don't know what could be the problem. Do you think my graphics card could have gone bad and if so how do I switch back to my on board graphics, or if not what else could be the problem.

If I load default settings in BIOS for windows 7 will i lose all my data and files? My computer is a Dell Inspiron 570... I believe. It has power but when I turn it on the screen is black. I can get to the BIOS setup utility menu. i just wanna make sure if I load default settings I won't lose everything. The BIOS is the only thing i can get to on the computer and the screen only shows the option to hit F2 for a second. Tried to get to safe mode menu but have had no luck

Answer:Computer comes on but screen is blank. Can only get to setup

Another option - at least to save data etc. - all the "stuff" you don't want to lose - for whatever reason... Download an Ubuntu ISO (ubuntu.com); save to a hard drive; burn to a DVD; boot the damaged system with that DVD.It will (barring major hardware/RAM issues) load itself into RAM "only". You can then look for the "resident HDD" and copy all your "stuff" to external storage. Typically most will use DVD only; but I tend advocate two external storage media if possible. DVD - yes and also an external HDD. No storage medium is perfect... and if you have two sets of data - DVD and a HDD the likelihood of both failing at the same time is???Then you can set about resolving what ails the damaged system - knowing data is safe elsewhere.To slave the drive from the damaged system to another system; remove the drive from its present installation and connect it via a usb adapter. They come as simple set of cables and connectors; or a docking system - various styles (SATA only, EIDE only, SATA/EIDE). I have the cable set and it works fine; the docking system is tidier and allows possibly a few other minor benefits too. The cables systems come in as "very cheap" and a little less so. I wouldn't advocate the cheaper/cheapest version; go for something a little better - and perhaps check any reviews for them (typically Amazon.com or .co.uk) message edited by trvlr

I have an Acer laptop that will not boot. The Acer insignia comes up as it starts then there is nothing after that but a blank screen. I cannot even run a Windows XP recovery or reformat the HD. When I set the bios to boot to CD first. The same blank screen shows up.

I installed the HD into another known working Toshiba laptop and the same problem occured, the Toshiba insignia comes up then...nothing. So I don't think it's a hardware issue. I then took the drive out and put it into a 2.5'' USB HD enclosure and I was still able to see and transfer all my info from the drive so the data is still there, it just won't boot. Shamefully I must admit I haven't updated my virus protection in some time. Could this be some kind of boot virus?

Thanks in advance for all help offered.

Answer:Computer will not boot (XP) - blank screen

If you can put the drive into an external enclosure and see it, can you format it from another computer? This may be the only option as Windows setup isn't working.

Purchased new computer approx. 2 weeks ago. First 2 days worked fine but on 3rd day computer appeared to shut down for no reason. Power was still on, but screen was blank, would not respond to any input. After pressing 'reset' several times computer booted normally. Over the next few days it repeated problem about once or twice a day, I then noticed the clock had reset to April 2002. After about a week the problem had gotten steadily worse, I also noticed the message CMOS BATTERY STATE LOW. Is this a valid error message or just a sign of something bigger? I've never gotten this message on any computer I've ever owned. I removed all my devices except video and booted to a floppy with the same results.

BTW, I have a Athlon XP 2000 w/256k and the mainboard is a ECS K7S5A. I've checked all my devices on a second computer with no problems.
 

Answer:Computer reboots to blank screen

Hi there...

It sounds like you need to eithr get a new CMOS battery or call the motherboard/CPU maker and see if you can get it repaired/replaced!

When I turn on my computer it shows nothing but a blank screen. Doesn't even go into bios 19 out of 20 times. Every now and then it boots into BIOS and begins loading Windows, but freezes at the loading screen. What could the problem be? A couple months earlier the computer would randomly shut down while I was using it. I'm assuming the problem might be the probably the power supply. It's an emachine t3624: http://emachines.com/support/product_support.html?cat=Desktops&subcat=T Series&model=T3624#

And yes, I know I really need to upgrade to a new computer... but I have absolutely no money I can put towards buying one at the moment. It would take me at least a couple months to be able to afford even a cheap one....

Whenever I turn my computer on I get a black screen and it doesn't budge from there. My monitor just seems to go into sleep mode and I can't do anything. Also my dvd drive makes this horrible sound whenever I start up my computer so I swapped out the drive with another one I had around the house and it made the exact same noise. I even took out my hard drive to make sure that wasn't what was making the noise. I've never encountered such a strange problem before. I tested the optical drive in another computer and it doesn't make this noise. I just have no idea what could be causing it. Any suggestions?

Answer:Blank screen when I turn my computer on.

Since no one else will try this one I will have a go.

First if you have no picture, why are you playing with the dvd drive?

Graunching noises suggest fan problems. Either a fan is clogged up with dirt or catching on an internal cable or just wearing out. Check all these including your graphics card.

At best this is your problem and restarting the fan will restart your picture.

Next best option is the power supply failing, not providing proper power to dvd drive and graphics card. Check by substitution.

If this does not work you have cooked something, this could be any or all of, memory, processor, graphics card. Depending on the specs of your other pc you may be able to check these out, one at a time, by substitution.

Post the results and good luck

Hello to the readers out there

I am having a problem with my computer. I dont know if any one can offer there support to this problem, or there could be some one out there that has experienced the same problem.

Here is the problem. My computer screen, seems to go blank, being all white screen. It seems to happen, when you do stuff on your computer. like clicking on icons to bring up the internet, also yahoo mail etc. To get rid of the white screen I need to click on to the desktop icon to make the white screen go away. You think it has gone, but it is still there, when you do the same thing clicking onto icons it seems to keep on going blank white screen. It gets annoying clicking on the desktop icon all the time.

Some days the white screen may not come up.

Would any one please, provide info about this problem I have.

Thank you for reading.

Brian
 

Answer:Computer Screen goes blank and white

Have you done a spyware scan or virus scan? Usually we call them the blue death meaning it will crash. Do you have ur back up cds to reformant? When you only reformant is to correct what ever the problems is unless you are going to smoke out the hard drive an start from scratch an reload everything. Hopes this help!

What windows are you using you didn say what you were running.

I recently bought a used computer from my work (a gateway). I'm sure they remove a lot of stuff before reselling them. When I hooked it up, it makes the music likes it's coming on, but the computer screen stays blank. It's like it's putting itself in sleep mode or something. I can't get to the control panel or anything. Does anyone know what is causing this? My place of business sold several of these, and I haven't heard of anyone else experiencing problems. Is it possible I need to run some kind of disc if they removed something vital? Thanks for any help.

My configuration is Intel Core 2 Duo E6600, X1950XTX Radeon, 2gb ram, 250HD, 500w powersupply.
So one day I'm using my computer, which had been working wonders for 3 months, and it just shuts down. Then it wouldn't turn back on, at all, no power anywhere. So, I replaced the power supply. I made no other changes other than the power supply. Now it powers up, all the fans turn on (including from the video card), LED light turns on, even the CD rom driver works but I get nothing at all on the screen. And since i get a blank screen with both of my monitors I can't see how it's a monitor problem. I also get no beeps when I turn the computer on, and although I am not sure, I think the hard drive disk spins.

I can't see how it would be the video card since it was previously working and nothing changed on that. The only thing that makes sense to me is that when the old power supply broke the motherboard or, i hope not, the CPU got damaged. Has anyone seem or heard of someone having a similar problem? What Should I try? How can I find out if its the mother board or the CPU malfunctioning? Thank you for the help.
 

Answer:Computer Turns on but Screen is Blank! Tried Everything, Please Help!

Hello and welcome to Techspot.

First things first, when you installed the new PSU, did you connect the power cord to your graphics card? Did you connect two power connections to your motherboard? Both the 24 pin and the ATX12v connectors?

Assuming you did, I'd strip down to the basics to help with the troubleshooting. Remove your motherboard from the case, and set it on a box beside your case. Intall ONLY the cpu/heatsink, one stick of ram and your graphics card (unless you have onboard graphics as well, in which case do not install your graphics card).

Connect the case's speakers to the motherboard.

Connect your monitor to the graphics, and then use a screwdriver to quickly "short" the two pins normally connected to the case's power on switch.

Tell us exactly what happens at this point. What lights are on, what fans are spinning, and what beeps you are getting. Good luck!

Also, please give us your motherboard make/model number, as well as your PSU maker name.

The other day my daughter told me her computer turned on fine, then the screen flashed on/off and she had the monitor adjustment icons showing on the screen (but they could not be adjusted). On the CPU the power light was on but you could not turn it off by holding in the button. If you pulled the power cord for a few minutes and then plugged it back in the power light came on, it tested the DVD Drive, but it did not run through any start up, the CD did not run and no display other than described above was on the screen. Can not seem to get it to boot for the recovery CD. Any idea what might be wrong? It is an emachines 2800+ AMD Athlon XP Processor.

Hi, i have solved the problem with my computer.I discovered that it was indeed the motherboard that was faulty.Even though i tried some of the suggested methods of troubleshooting,they were ineffective.I heard beeps when i took out my ram from my computer,so i guess that method of determining the motherboard is fine is not always right.Yes i now have a newer and better motherboard.

I just got this HP pavilion 762n last year. Now whenever I turn the computer on it won't respond and the only way I can make the computer respond is to go to safe mode and Un-install the Graphic Card, then restart the computer back again. Once I've done that the computer would work, but I can't watch videos or play video games and their would be these little blue lines on the computer screen (Sometimes their would be alot of the lines and sometimes the lines would be made by the trail of my mouse).

I've tried lots of ways to fix the computer. I've tried doing a destructive recovery lots of time and it still wouldnt work. I have this program that test my computer and tells me what kinda problem my computer have and it said that the computer fail on the video memory test. I think the only way I can fix this is to buy another graphic card. Can anyone please tell me how to fix this problem?

My computer is having this weird problem where when I finish logging in, the desktop would just be purely blank. The mouse cursor does show up and i can control it, but none of the normal desktop things would show up (wallpaper, taskbar, icons...). If I hold down the power button and force shutdown, and then go into the safe mode when i start up, all would be normal (except for the wallpaper of course due to the safe mode). If i restart from there i would be able to get my desktop back. However if i reboot the problem comes back.
 
Also, the computer lags significantly when the desktop is gone since the task manager usually goes to "not responding" state.
 
Is there a way i can fix this problem? Restore point would not be an option since the problem started about two years ago when it was not very serious. I tried to locate the problem but explorer.exe and dwm.exe are both there...

Answer:Computer Blank Screen After Logon

Could be a problem with corrupted system files. If you can get to a command prompt, type cmd in the search bar, right click the command prompt icon, select run as administrator, and run the command sfc /scannow.
 
If that doesn't work, try running from a clean boot. Don't try this if you're not comfortable with advanced level troubleshooting. Also be aware, this is a time-consuming methods.
Click the Start button, type msconfig in the search box, press enter.
Click the Services tab, check "Hide All Microsoft Services" and click "Disable All" if it is not grayed out.
Click the Startup tab, click "Disable All" and click OK.
Restart the computer. When the System Configuration Utility window appears, check the "Don't show this message or launch the System Configuration Utility when Windows starts" box and click OK.
If the issue disappears in the clean boot environment, turn half the Microsoft services back on, and restart the computer. If the problem doesn't recur, turn the other half of the Microsoft services back on. Once the problem reoccurs, turn services off and on to narrow it down more specifically.
 
Or, you can just launch the clean boot troubleshooter from here: http://support.microsoft.com/kb/331796
 
Hope that helps. But if this has been going on for a while now, it may be hard to pin down at this point.

Greetings all,

I'm having a problem I haven't encountered before. My computer will boot up Windows XP as normal, then after 1-2 minutes the screen will go blank and will not respond (must manually turn off power switch), although CPU fans and power are still running.

Rebooting is also problematic, as often the lights turn on, but there's no HD activity, BIOS beep, etc. Will only boot every 5th or 7th time, which it does successfully, only to go blank and unresponsive again after a minute or two.

I've tried booting in Safe Mode and have the same problem.

Any suggestions? I take it this would be a hardware problem?

Cheers,
Jeremy

Hello,

I have two questions that might be connected.
I wasn't sure about where to post this, because I'm not sure if the problem is my screen, windows 7 drivers, video card, bios or something else.

I used to have two screens connected to my computer, now I only have one (I think it has something to do with the problems).

Problem1: Every time I power my computer, the computer itself turns on, but the screen stays off until windows 7 loads, then the motor turns on.

Problem2: Many of the times I put my computer in sleep mode, and try to turn in back on, I hear the computer turns on, but the screen shows nothing.

The screen itself is fine, if I restart and let windows load properly, the monitor works.
I updated my video card drivers.
And now I don't know what to do, I want to format my computer and reinstall windows 7, but I can't get into BIOS and boot from USB / CD because the screen is blank when booting.


Please, help! :)

With every computer I've owned before, the screen going blank does not lock my computer. A quick move of the mouse or touch of the keyboard used to restore you to your logged in session instantly. With my T410, any time the screen goes blank, my computer locks itself and I have to swipe my finger to get back in. This is very annoying.I can disable my computer locking itself when it goes to sleep and that fixes this, but I WANT my computer to lock when it goes to sleep, otherwise the finger swipe to resume isn't even an option....plus if my computer is asleep the chances are much higher that I am not near it...and I want that security in place. Does anyone know of a way to get Lenovo's software to only lock the computer after sleep or hibernate and NOT simply after the screen goes blank?I have never seen a computer lock itself after going blank before so I really have no point of reference to fixing this. It just occurred to me that I might be too loose with my words. I am not talking about the "screen going blank" like back in the days of screensavers and the screen still being on....I am talking about the screen turning off, as in a function of power management.

Answer:Computer locks after screen goes blank

Screen turning off is controlled by Screen off timer, typically 5 or 10 minutes, what about your screen saver timer, if they are the same, you will see screen turned off, and at the same time, the screen saver program starts!

My laptop will boot just fine but nothing comes on the screen. Its a bit older so I figured I had nothing to lose so I took it apart. When I did that, I found a piece (which I am not sure what it is) that was broken, and put it back where it obviously went. I booted the computer and the screen came on. I didn't have any drives in so it said "no drives found. " I thought I had found the culprit, so I put the drives back in, and now it won't work again. I've looked online every where to try and find out what the broken piece was or what it does, but can't find it anywhere. My best explanation of the piece is; its a black square

Hey,

I was playing Tiger Woods 2007 yesterday and my computer was running a bit jerky which i thought was strange but what I thought was even more weird was when it just turned off; no power, screen black all of a sudden, dead.

My machine is:

AMD 64 3700+ Clawhammer CPU
Asus K8N-e Deluxe Mobo
1gb Kingston RAM
250gb SATA drive
X1600 256mb Radeon Graphics Card

So, my spec isn't THAT bad, quite good i thought but it did just die! Now every time I turn the thing on I get life inside the case but nothing on screen (not even a bleep from the hard drive to say it's alive - though I can hear it spinning).

I've spent a while now taking out parts, blasting them with compressed air to remove dust, putting them back in, testing, retesting, re-retesting and so on. I've tried a friends graphics card ( i burned my last one out video editing and playing games! so checked this first!) and have tried different memory in it too in all the available DIMM slots so I know it's neither of these. I've looked at the processor and no pins are bent, no signs of overheating, the motherboard looks ok, i've tried booting from an old hard drive that was installed in the same system a while back (even though when I was doing this I though "well even if it was the hard drive I should still get life from the BIOS atleast!").

I have a Compaq SR2173WM w Vista. Everything on it is standard specs for that model. After I installed the virus protector, AVG 8.0, I have had problems with the screen being blank after the computer is turned on. I have taken everything out and checked all connections to make sure nothing is broken or loose. Occasionally it will show on the monitor and everything works fine.

My uncle builds computers and he built me a brand new one about 2 years ago. It's worked really well for both years until now. I was off for Thanksgiving vacation for a week and I left the computer on for the whole week. Usually the computer is perfectly fine to stay on for long periods of time and never shuts down or needs restarted. About the third day it was on, it froze and needed to be restarted. Over the last 4 days, it needed to be restarted about 3 more times. I figured it was just because I was on it a lot and saving a lot of work on it. On Tuesday night, I decided to shut it down before I went to bed. When I went to shut down, it said that all of the programs that were currently running were having trouble shutting down (my fire wall, instant message, and internet explorer). I canceled all of those programs and when it didn't shut down after a half an hour, I finally just shut it down with the power button on the computer. The next afternoon when I went to turn it on and the screen that comes up (I forget what it's called) with the Energy Star thing and all of the writing in white on the black background did come up, and I'm pretty sure I saw a glimpse of the Windows XP loading screen, but I'm not 100% sure.

Answer:Blank screen and computer is beeping.

When you say you checked the memory sticks, what do you mean? Did you test them in another machine?

Continuous beep code is sometimes a hard one to diagnose. Top suspect is your ram, followed by your PSU, video card and mobo itself.

To test your ram, either try some other ram in your system, or try the ram you have, in a known working system.

To test your PSU (assuming you don't have a voltmeter), replace it with a known working one.

Sounds frustrating, but that's what you are going to need to do, and if you don't have the spare parts to mess around with, you'll have to take her into a shop and let the pros fix you up.

Good luck!

I have a self made PC with Winfast Foxconn MB, AMD64 3000+ socket 754,
ATI 9250 AGP.

I installed everything, connected the cables but the computer does not turn on. I receive a blank screen and nothing else.

The MB and proccesor worked previously on a different system that I have upgraded.

What can it be?

The FANs are working, I can not turn it off from the power button.

Please help me.
 

Answer:My computer does not start, blank screen

If you get no beeps Id suspect a bad connection... I have seen this on the CPU. Simply remove it and reseat it. I have also seen bad AMD boards do that. I saw on two seperape occasions exactly what you describe... if I let them sit there for 5 minutes to warm up and then restart them they worked. In that case the problem could be cold solder connections somewhere on the mobo. Not a good situation as most computer users dont have the skill or equipment to find that type of problem.

Answer:Blank screen when turning on computer

Im starting to suspect that my graphics cards is failing. Weeks ago, when i got my com to start after restarts, in firefox the mouse seems to have spiky movement and when i attempt to start warcraft 3 it says that direct x failed to initialise. A restart solved those problems though....

When I turned on my computer its only an orange bar. I cannot even see the windows logo or even get into safe mode.

The night before I was using my computer as normal and everything was fine, it shut down completly. The next morning turned on the computer and all I see is a blank screen. Now keep in mind. This has already happened to me about 3 months ago. Some symptoms I just replace the video card and that fixed the problem.

Back to the problem, Listening to the computer as I turned it on. There are no "Beeps" or any sound referring to any problems. I open the case and all the fans are spining, hard drive make regulars start up sounds as well. BUT it never loads windows.

I went to the store to buy other video card (brand new) installed it correctly and it doesn't fix the problem. At this point I am thinking it's my motherboard or it's my monitor, which i know isn't the problem because I borrowed my friends computer (case) and I am using it on my monitor as I write this.

2 days later

I removed Everything out of the computer case (motherboard, CPU, harddrive etc...) cleaning all the dust off of it.

1) I tested all of the hardware on a friends computer and they all work.
2) Scan for virus, Did a defrag, scandisk of the C drive repaired everything on the harddrive.
3) I installed all the hardware back on my computer and tested it. but still nothing works.

At this point I am getting very angry. I'm pressing bottons restarting th... Read more
