computer screen turns off and other things

Question: computer screen turns off and other things

So, obviously I don't know whats wrong with my computer. I play WoW and that shouldn't be to hard on my system. Whenever I play, my screen goes all wonky after awhile, sometimes its 10min, sometimes it'll last an hour. There will be bars going across the screen and the graphics will be all screwed up. Sometimes my monitor will just shut itself off and won't turn back on, I'll have to restart to get it to turn on again. Other times my computer will beep and shut off completely, sometimes a blue screen will come up with a bunch of writing, but it turns off so fast that I don't have time to read what it says. Its usually fine doing anything else, browsing the net or even watching a movie, its when I play a game it gets all screwed up. When I'm not even touching the computer it occassionly turns off! Well idk if it actually turns off but my tower will go completely silent, then it will start up again but it'll be on the exact same screen it was on to begin with, it doesn't restart... idk what it does. But when that happens a msg comes up saying 'usb device not recoginized' and i have no usb devices plugged in that are not recognized. The unknown device is apparently 'Universal Serial Bus controllers'... idk what that is, but when i look in my device manager thats the only unknown device. Hopefully someone can help me!

Answer:Computer Turns Itself Off And Other Things

My first thought is adware, spyware or even a virus. There was a virus floating around months ago that would shut down the computer. It is possible that it wasn't shut down properly (power failure) and there are important files that are corrupt. It is also possible that the hard drive is going bad. My laptop did the same thing when it's hard drive died.

Assuming that there's a problem with your hardware, your computer manufacturer sometimes provides some self diagnostic programs to determine what's wrong. If you have a Dell or Compaq/HP, there should be a diagnostic CD that came with the computer that you can run.

Can you tell us about your computer?

I've read around and tried the following:

Alt+F4

removing the battery with the power cord unplugged and holding the power down for 20-30 secs (reset BIOS?) then put the power cord back in and tried to turn it on.

Just turning it off and on a few times(I guess it could be stuck in sleed mode?)

I tried to light up the screen with a flashlight to see if the LED went out but screen was still black.

It's a toshiba satellite sli1

Thoughts on other things I can try?

So one day a week or two ago I turned on my PC to say that it had an issue and it needed the windows installation disk to repair it. So I put the disk into the PC and I clicked repair and it took a long time but it said all issues are resolved. I was happy as I thought I solved my problem, however, to my disappointment I was wrong. The computer reset and I saw the dell logo and the loading bar moving across and everything however after I wait the screen turns black but i can still see my mouse cursor and if I move the cursor around I can see it move but just my wallpaper is not there, the windows bar is not there, my folders and shortcuts aren't there nothing is. I tried pressing CTRL+ALT+DEL to bring up task manager but that does not work. I didn't make a backup recently and I put the repair disk back in and I scan for issues and it says there are no issues. I'm at a loss here and I'm desperate. I have all of my photos that I have taken from my vacations over the past 4 years and I can't get to them so I was really hoping that you guys could help me fix my PC. If anyone could  help me I would gladly appreciate it.

Hey Jason,
 
Some times 3rd Party software creates conflict during the startup.

After getting a couple blue screens I am having the following issue:

When I turn my computer on, the fans and drives all start up. After approx. 2 seconds the computer shuts itself off. After another 2 seconds the computer turns itself back on again. This time it stays on but i have no monitor output. I don't hear a beep which tells me it is probably not posting.

I have read a few other threads that have a similar issue but not the same. I am thinking it is either the mobo, GPU, or PSU.

I would like any guidance and assistance that you guys can give me on this specifically what i should look at first and how to diagnose. Thanks. system specs below:

ASUS P5Q Pro ATX Intel Motherboard
Intel Core 2 Duo E8500 3.16GHz LGA 775 65W Dual-Core Processor

I have helped somebody who had a similar issue and it was the motherboard being shorted out by the case. We took the motherboard out of the case and it booted up just fine. Something you might want to try before purchasing new components.

My laptop is a Gateway 450 ROG and it has had this problem for the last week. It will run for roughly 40 minutes, and then (even when small programs are running) it will freeze up. My mouse wont move, no command will respond and i am forced to hold the power button and shut it off.
2nd Problem, occasionally when i turn on the computer it wont boot up. The screen will turn on and stop with a dash blinking in the top left corner, not proceeding to any boot up of any kind, and just recently while i shut it down from this sort of freezing up, little pictures of pixel hearts and dots started appearing until i shut it off. This problem has gone on since i bought this computer from my brother but the pictures havent until this last week .

Hi,

My computer's screen recently turns off once in a few hours. Sometimes days.
Before it turns off, the computer gets stuck for 2 seconds.

I wonder if it's overheating of the CPU or something else.

What do you think?
 

Answer:Computer screen turns off

I've connected another screen to my PC and it just turned off, so the PC itself is the problem.
Any idea what can cause this?

Ok, I've been going through some of my old stuff and found some old computers, and i've been trying to build a system from different parts. These are the following:

Videocard: 7600gt
Motherboard: P4 Titan 533 GA-8SR533
RAM: 1gb PC3200 DDR HYNIX
CPU: Pentium 4. (im 99.99% sure, but the written stuff has been rubbed off =(..)
PSU: Codegen 300W

I've built this system, took it apart, dusted it all off did EVERYTHING i can to try and fix it. When i try and turn it on, it turns on, (i can tell by the fans spinning and lights turning on the MB) but nothing comes up on the screen. I know its not the monitor because when i plugged the monitor out of the videocard, it says no signal on the screen. When i turn the computer on im pretty sure its not the videocard because the screen's power is blinking with green? (thats what i read from the internet )

So i tried my best to fix up this old computer, and the last option i need is anything involving MONEY, (Im veryyy short on money atm...)

Thankss =]
 

Answer:Computer turns on but nothing on screen

Have you installed the drivers for the 7600GT ?
That is probably not the problem, but the card may be defective... How do you know the video card is good? If not working, it may not show anything on the screen.
Can you test it in a friend's machine?

Ok so my brothers computer will turn on but there is no screen, it says "no Signal".

heres the story. When I unplug the computer from the wall then plug it back in, it will turn on automatically. The computer will also not show anything on the screen..I've tried changing out power supplies, video cards (the current video card he is using is on board, I switched to after market) I also tried changing all power cords and display cords. I'm not sure what else it could be other than maybe the motherboard or harddrive? Its a Dell with windows xp I don't know much more about it other than its not a pavilion is a custom build from a local dealer. Any and all insight/advice would be helpful, thank you.

Answer:Computer Turns on but no screen?

Try clearing the CMOS. There should be a jumper on the motherboard labeled "CMOS CLEAR". If you can't find this jumper, then remove the battery, unplug the computer from the wall, and push the power button. After this it should boot. If it does not boot make sure that the PC Speaker is plugged in to the appropriate jumper and pay attention to the code coming from it.

Report back with your findings as clear and concise as possible.

MOTHERBOARD: M3N-HD HDMI
CPU: AMD 6400 duo core
RAM: 4gigs
Video: Geforce 8900

I was playing a game when the system just turned off. Prevously, I had a few times it reboot. The system will turn on ( fans and leds' ) and HD loads and CD loads but I get no video on monitor nor do I hear any system beeps or seems like it is getting past the BIOS load. I took the machine to a shop and they said my PSU was bad... So I purchased a new one online since nobody locally carries anything above a 450w same one as I had before 700W. I installed new PSU but I get the same simptoms.

I took out the motherboard out of the case and put only 1 stick of ram in it reseated the cpu with heatsink and fan with new heat paste. Plugged in the VGA adaptor for onboard video. Plugged power into the motherboard at the main adaptor and the cPU 12v. I short the power swt to turn it on and I get the same thing. Fans turn on LED on. No beeps or video. I tried a 2nd speaker and tried again no change. Any suggestions?
 

Answer:Computer turns on but no screen

It's possible you let your computer get too hot and it burnt up the motherboard... that or possibly the graphics card... if it's getting power but not posting, then it's not your power supply, although it may have been bad too. It's either going to be your motherboard, graphics card, or processor... a failure in either three could cause it to not show up... You saying it doesn't have any bios beeps leads me to believe it's either the motherboard or the processor, not just the graphics card.

I have an Ispiron 530s desktop (XP Home). When I try to turn on the computer, the CPU fan is very loud and constant. I get no desktop. Both the monitor and the computer on/off button are amber color, no green. What could be the problem? What should I check first?
 

Answer:Computer turns on to blank screen

Usually the amber color indicates a power problem... as if your power adapter or cable to the power adapter is broken, or the power socket is damaged.

First off, this is my first time on these forums, and i'm not sure if it's in the correct ones, so if an admin can move it or something? thx,

Allright, so about 2 and a year ago i bought my MSI, which i've been enjoying quite a lot. I use it daily for gaming and school related work, but 2 days ago, the screen suddenly turned black (while gaming) and then said a kind of "RRRRRR" noise. I restarted it, and it worked fine again.

Today, the computer did the same thing 4 times, expect that the screen turned light blue this time. It still said the "RRR" sound, I update my drivers regularly, and i just updated them before it happened again. Restarting works by the way.

I'm using a MSI GT663R, with these specs:
CPU: Intel core I7-720QM
VGA: NVIDIA Geforce GTX 460m / 1,5GB DDR5
LED Panel: 15,6 FHD, 1920x1080 (Glare Type)
Ram: DDRIII 6GB (2GB*3)
HDD: 1TB (500GB*2 RAID 0) 7200RPM
RF: 802.11b/g/n

That's atleast what it says on the sticker on the PC, note that i'm not very good with computers and i'm really hoping to get a simple fix, because i don't want to use money to get it repaired if not necessary.

Thank you really much in advance, i really love my PC, and it was quite expensive, for what i earn, so i really hope it isn't broken or something similar

Ok so, im trying to help my friend with her broken computer.
She got hit with the avsoft virus, It took me a while but I finally got malwarebytes on her system, and had to rename the .exe in order to get it to run in safemode and it seemed to have worked pretty well, i then wanted to boot it in normal mode and run a full scan to make sure we got everything.
Anyway, we were experimenting with it for whatever reason (i guess malware removal had us feeling brave) and we unhooked her monitor, and plugged her desktop computer via the monitor cord into my laptop. i know that you can plug a monitor into a laptop and use that instead of the laptop screen, so we wanted to see if it would work with the desktop instead of the monitor. You know, like use my laptop as the monitor and keyboard.
I went into the my laptops nvidia control panel and messed around with some of the settings
All of a sudden my laptop screen went black.
I just rebooted, and my laptop was fine but when we plugged her monitor back into her desktop and rebooted it would not reboot correctly.

The lights on the computer would turn on, you can hear it is running, the fans are running, it makes one beep, just like a normal startup. the screen displays a logo (not the windows logo) an everex logo for a few seconds, and then some text comes up (like normally) and looks like it proceeds to load but it flies by so quick you cant read it, and then nothing.

Hi, at first I thought this might be virus related. I went through with help from Howard_Hopkinso, and removed all virus' and malware. But my problem persists.

I have an Alienware Area 51 m7700, 120 Gig HD, 3 Gig memory, 3.8 GHz Pentium 4 HT duo processor. NVIDIA GeForce Go 6800 Ultra.

What happens is when i try and playing a source game for little while the screen goes black, sound skips, but the laptop still runs. Also happens when i click on certain internet links.

I assume that i need updated drivers, which i did. but that didn't work either.

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.

Hello. I've come to hopefully find a solution to a boot up problem I'm having with my computer. There are several factors that I'm honestly not sure will play a role or not, mainly because I'm not very understanding when it comes to computers.

The problem is that when I push the power button of my computer, it sends no signal to my screen. I can't tell if it loads anything or not either. I can think of a few things that might have some effect on this, but I'm not sure.

About three months back after cleaning my neglected tower of dust and such, it started to shut off rapidly after boot up. To inspect the problem, I had a friend look at the computer. He removed the cooling unit on the Processor revealing that my 8year old computer had next to no thermal compound. So after putting of ordering some for about three months, we had applied some about 2 days ago. The computer then booted up fine, but seemed to have an excess amount of lag. So I wiped the computer and reinstalled XP tonight. When it was booted up, it worked fine, so I went into IE to download firefox as it's my preference, then started reinstalling my drivers. First I installed my Videocard, then kept my computer booted up for my sound drivers which I got from the Compaq homesite. After doing this, I rebooted my computer. Not I wanted to get simple things such as AIM and and Java. So when i go to boot up Firefox from it's default homepage, my computer shuts down. when I go to reboot it, it doesn't start and I'm ...

Hi I have a Dell Inspiron 1501 and I got it for my birthday, I think I got it on the 13th of September, it worked completely fine for a long time and then I can remember one day I just would not turn on, I tried and tried to get it to turn and it just wouldn't do it, the next morning it turned right on...with no problem at all, and then it was fine until about the end of January, then it turned off once and I got it to come back on after trying several times, then the next day when I went to use it again, it would turn on but the screen would not work, and it has been like this ever since, I have gone on the dell technical support website and they were no help at all. They had me taking out the hard drive, and the media board, and all of this other stuff and they didn't tell me anything, all they basically had me do was take it apart and put it back together. My father bought me this computer and it was the last birthday present I got from him before he passed away, so I am deeply attached to it.

Could be a number of things most likely your graphics card/ monitor, is your computer situated in a particulary warm or cold place?

Checked the fuse?

Is the environment particularly dusty?

Do the cables look secure in there ports?

Have you tried holding in the power button on your computer without any power leads in?

these are some basics to try, if that doesn't work we need to address a deeper issue.

A friend asked me to look at her Toshiba Satellite L455 Laptop. Apparently her dog chewed the power cord while her daughter was playing on it. The computer shut down. I replaced the motherboard thinking that was it and that didnt help. I replaced the screen inverter and the backlight and neither of them worked. The computer does turn on but the screen is black.. What could be the problem? If I replace the screen would that work?

Hi Everyone,
This is my first time posting on these forums. I have a dell inspiron 5447, and I love it. It looks great, and, for the most part, runs well. However, whenever I move the laptop, or even slightly touch it, whether i move the screen or touch the body of the laptop, the screen glitches on and off, sometimes a few times in quick succession. When this happens, the touchpad also disables itself, and sometimes turns itself back on, but I usually have to go in to mouse settings and disable the mousepad and reenable it for it to work. I am thinking I need to send it in to be repaired, but I am not sure what the problem could be, or how much it may cost. I am also a college student that needs a laptop, so I cannot be without one for a long time. 

Thank you for your help.

Answer:Computer Screen turns on/off, touchpad does the same.

Please run the diagnostic tool to check the hardware on the system by following steps below.
1. Power off the system. Remove all peripherals except AC adapter
2. Power on system, quickly start tapping the F12 continuously until you see Preparing one time boot menu in the top right corner of the screen. In the boot menu, stroll down to Diagnostic and then click on it.  After quick tests, click on Hard drive, and select Thorough Test Mode.

Answer:Computer turns on, but black screen :(

Inverters and bad backlights can be hard to diagnose without just replacing the parts but it sounds as one or the other is out/going out.
If you check these out yourself, good luck. Laptops are a bear and unless you've done a few, a repair shop may be best.
Good luck.

Turns out all my problems were an aged battery, according to the tech shop who reinstalled windows after some deeprooted viruses. But now my laptop won't shut down all the way, but the screen turns off. The keyboard's LEDs stay on, and the fan keeps blowing. It stayed that way for at least five minutes, between me getting a snack and coming back. I don't know if they reinstalled from the disc that shipped with the laptop or gave me a knew windows 7, but this particular issue only started when they reinstalled the OS.

Answer:Computer won't shut down, screen just turns off.

Nothing to do with default power options?

After running my computer for approximately 10 to 20 minutes the monitor shuts down without any warning and simultaneously the sound cuts off, rending my computer unresponsive and useless. I suspect it's overheating but I have never experienced these issues before, they are obviously obstructing my work.

I have an ADM Radeon HD 5670 and I have never experienced or noticed the device reaching over 60 Celsius. The ventilator works within normal parameters as far as I can see with the Catalyst Control software and as far as I know all drivers are up-to-date.

I have posted my system information in a previous post regarding BSOD here in case it is of any relevance.

I hope someone is able to provide me with some help, I'd hate to buy a new video card.

Answer:Screen turns off, computer frozen.

The PC itself shuts off or is it still on? This is an important factor!

If it just completely shuts off, most likely one of these:

You could be having a power supply going bad.

You could have a dead case fan.

Thermal paste and/or heatsink/fan on CPU has failed in some way.

Heating failure is something that just shows up one day, so welcome to the wonderful world of PCs.

Hi all,

My faithful desktop of 2 years has started pushing up daisies:
I was playing GTA5 when the monitor lost connection to the computer and I had to restart. When I started back up, the message that appears after a bluescreen popped up. This started happening more and more frequently, whenever I started any game, then sometimes when I'd just have Firefox open, then about half the time I tried to start up the computer it'd happen at the login screen.

I did a Malwarebytes scan a few days before this started happening and it turned up clean, and I haven't changed the hardware in 2 years. I tried updating my video card drivers, to no avail.

The weird thing is how inconistent it is--I was able to play GTA for several hours last night, then it happened again. Sometimes it automatically restarts, sometimes it doesn't. Sometimes the power light flashes. Sometimes it makes me go through Startup Repair (which never finds anything).

I have no idea what could be causing this. BlueScreenView says it's a graphics driver about half the time, but not all the time. Memtest86 said the RAM was fine. Any advice would be greatly appreciated.

I can post SysInfo results and the minidump files if they'd help; I'm on my laptop right now because the system in question is really unreliable.

Thanks in advance.

Hey guys I'm hoping for some help on this one, since i can't seem to figure out what exactly is wrong. I've had my Y510 for about 2 years or so and the only thing ever to go wrong was the right hinge. All of a sudden the other day, I would turn my computer on and only the media buttons/ processor lights would turn on. The screen was totally blank, not even backlit or anything. I tried connecting the compter to an external monitor but I still didn't get anything. Even pressing the NOVO recovery button didn't do anything. Any Ideas would greatly be appreciated. UPDATE: I was reading an article/faq that showed very similar to my problem, however lenovo says I need to update my BIOS. But how would I even going about doing so when I can't even get the lcd to turn on?

Hello, I've been experiencing this problem off and on for the past couple of months, where the computer screen just turns fuzzy and crashes, then five seconds later is completely black (like the monitor is on but is not connected to the computer) I believe this generally happens while I'm surfing the internet (Mozilla) , often (perhaps always, I'm not sure) when I'm watching streaming video.

Ran a couple of different anti-virus programs (Adaware, Malwarebytes' Anti Malware) and Adaware turned up a bunch of cookies.

This has only happened a few times, most of the time everything's fine. Any clue on what could be going on here?

Well it started awhile back when my PSU died so I got a new better one, but the computer would still turn on but stay at a blank screen. I tested my parts and came to the conclusion that it was either my mobo or CPU or both, so I went to the store and got a new Asus mobo and a sempron chip and installed them. The computer still has the same problem and I don't know why and what to do. Sorry for my english and any help is much appreciated.

Please use descriptive thread titles from now on.Thanks.
 

Answer:Computer turns on, but I get a blank screen after replacing bad psu.

So how did you test your parts?

Start with a minimal system - nothing but mobo, PSU, video, CPU and a single RAM module. Preferrably not in the computer case but on a nonconductive surface like a wooden desk.

If it doesn't work, replace the video (if external) and RAM.

Look over your habits. Did you take anti-static precautions when putting the thing together? (Something as basic as touching the computer case or the PSU before touching any other components.) Did you happen to work on the thing while it was plugged on and you dropped a screw on the motherboard?

This computer has been working since 2013, and just lately have I have been having issues.When turning on the computer, the computer sounds perfectly fine, all fans and everything works. There is no damaged, or burnt anything inside the computer. When turning on the computer my keyboard & mouse do not turn on, and the computer light works and doesn't work. I have tried everything that I can think of and anything that I have researched on the HP guides. And my computer still does not work. I have tried changing monitor, and the cables that connect to these monitors. I have bought a new PowerSupply and that made it work but once I had to restart it it did not turn back on (nothing pops onto the screen, it is black) I have a GTX Geforce 750ti FTW graphics card and nothing is damaged or misplaced. All connectors and connecitons work properly. I have reset the computer several times and it still does not work. Just now when turning on the computer the light (the botton) does not turn on, but the computer does indeed turn on. I don't understand that if there was something seriously wrong with the computer why it would sometimes work and sometimes not? If the motherboard was bad it wouldn't be working period, let alone working.  I really need some help, thank you.

well last night my computer was working just fine, I shut down, went to bed, woke up today and turned on my computer where it restarted after about 2 seconds, the screen didnt even get a chance to turn on. I have unplugged all the connections in the back and replugged them in, i have open it up and cleaned all the dust and removed all the hardware and replaced it all again to make sure there wasnt a part that wasnt fitted correctly. I managed to get it get all the way to windows once but my keyboard wasnt working so when i tried rebooting to get my keyboard working the same problem came up now i cant get it back on I am pretty sure windows xp has nothing to do with this as it cant even get the screen on before it is restarting

Answer:Computer restarts on boot up before the screen even turns on

Hi ShikariAtryao. Welcome to TSF!

This could be a number of issues. Bad PSU, intermittent RAM module(s), bad device in your system, etc. If you have more than one RAM module, try removing all of them except for one and try booting again. Make sure that the one module you use is in the correct slot as well. Step through that process exchanging RAM modules until you've tried them all and see if you're able to boot.

You could also disconnect devices such as your CD/DVD player (both data and power cable) and try booting again. It's basically a process of illimination. Also check the power cable to the motherboard and such.

One other thing is to check the little cables that connect usually to the edges of the motherboard. One of them is for your HDD, one if for the POWER LED, etc. There are usually several of them. Make sure they are all seated correctly as well.

Good day!

Mike

Heys, nice to meet everyone.
Well my first problem is that ever since i got my pc (6 yrs ago) it frequently restarted. So i turned off automatically restart & frequently got bsods. The first was DRIVER_IRQL_NOT_LESS_OR_EQUAL & the second one was PAGE_FAULT_IN_NONPAGED_AREA. I searched on google the problems and it said something about my NIC & Sound Driver. So i decided to open up my computer and try to swap my NIC whilst in the process just check out my graphics card and my ram to see if it was faulty, After that i turned on my computer and at first it beeped, then made this screechy sound for a split second and i smelt something weird. After that i turned it off re-inserted the RAM, NIC, GC & when i turn it on i get a blank screen. Both my cd drives keep resetting or blinking and wont open up, All my fans work & the red light and green light under my power button just stays there.

Specs of my computer:
- Pentium 4 2.4 GHz
- NVIDIA Geforce4 MX440SE 64mb
- PC333 512mb RAM x 2 (1024mb)
- 80GB HD + 120GB HD
- GIGABYTE Motherboard (MODEL: GA-8SG800)

The BSODs are caused when i play games like; Counter-Strike & Warcraft III. Also while i listen to music using WMP10. It can sometimes just be caused from sitting there.

Hi, having a few problems with my PC. Any help would be greatly appreciated.

A few weeks ago I came into the office to find my PC was making a strange "static" type of noise out of the speakers. The computer failed to power up, so ordered a new motherboard.

Fitted the motherboad today and put in a larger PSU. It powers up but nothing is displayed on my screen. Have tried a PCI Express graphics card and an old PCI graphics card but neither seem to output anything to the screen.

The PCI Express graphics card was working fine in the computer before it broke.

Another possible problem would be the CPU rather than the graphics card. I have tried 3 different processors (the one that was in the previous motherboard and two others) but using a different processor doesn't do anything.

Would it be right to assume that this must be a graphics card problem?

Could it be something else entirely?

Any help would be greatly appreciated as this is starting to frustrate me,
Thanks,
Michael

Hello all

Just got myself this (old) new computer, that I was going to use for a media center. But it randomly crashes, and i can't seem to figure out why. I formated it yesterday, so I doubt it would be a virus.

Sometimes it goes black, and picture returns within a few seconds, but other times it freezes up completely. When I restart it (with the power button) I cant get pasted the BIOS screen, but if I unplug the power supply, and hit the power button a few times and then plug in the power, it starts up like normal. (does that make it a RAM issue?)

Freezes have happened doing the following: Using XBMC (both in menus and while watching a video), while Internet Download Manager was running. While file transfer was running, and a few times while i wasnt at the computer.

Specs:

Windows 7 Ultimate x64
ATI Radeon HD 5670
Intel Core i3 CPU

Got the computer from a family member, I tried fixing it for them first and I thought it was the video card so I tried a different one and still nothing. So it was unplugged and stored for months then they just gave it to me. Well I took it home and started messing with it turned it on a cple of times nothing. Moved wires around put different psu in nothing, put it back to normal it started right up powered screen up I got into windows but it had a lot of lag so I went to restart it so I could do a fresh install and screen shut off... note when it wasn't working before this point the cpu fan ran at full rpm when turned on but slowed down when it worked this first time. I turned it on and off cple times nothing unplugged psuand back in it worked enough to reinstall windows and went to restart nothing. When plugged my speakers in to see if it beeps it started up! Its toying with me, restarted it again nothing so next try I pushed on the cpu thinking the mobo was bad it started up and woked for a cple restarts and quit... I tightened. The mobo screws down to the case and worked for awhile and then started acting up on restart. It will turn on once after it sits awhile unplugged with the bios battery out. I'm confused... bad bios or the mobo? I have unplugged all things that aren't needed for start up different hd with same effect. Only thing I haven't tried yet is the ram.

Answer:computer turns on but screen stays black

The PSU was probably bad, replacing it should have fixed it. There may be bad caps on the motherboard or something is grounding on the MOBO to the case and causing it to not boot. Take everything apart. Take Heat Sync off of processor and apply Thermal Paste. Take MOBO out of case and check to see if there are any burn marks, bad caps, or if there are any risers missing off the case keeping the MOBO from touching the case.

I have a Dell XPS 400 with Windows XP and when I turn the computer on, it turns on but only goes to a black screen with a blinking cursor. If I turn the power strip off and wait a few seconds then turn it on and turn the computer on, it boots. Help!! What could be wrong with it?
 

Answer:Computer turns on to black screen with blinking cursor

Replace the BIOS backup battery to eliminate one easy thing. You might get lucky and need nothing else.

Also be sure you have no CD's in the drive bay.

Hey, can anyone help me out here? My operating system is Vista. My computer suddenly goes into a blue screen and says that there is something critical in my system, and will shut down to prevent data loss. So I let it shut down, I reboot in safe mode, and I find that Windows Security tells me that the entire Security System is turned off. I tried turning it back on but an error message pops up. I used Tune Up 2008, and did a system restore. I rebooted and it said that the system restore was successful, but then the next day, the same thing happened. What am I supposed to do?

So. I turn my desktop on today, and it sits there, the main monitor light just blinks, my secondary monitor, after showing the MSI screen, just shows this http://i.imgur.com/hCBoFyd.jpg

After that, nothing. Computer is still on but nothing happens. I was thinking maybe something is wrong with my primary monitor, so I type in my password and hit enter. no sounds. I unplug my primary monitor and restart. No change.

My computer was also unplugged all night. The only changes made yesterday was the installation of System tools. Would that screw my computer over?

Any advice, tips, suggestions, or explanations are all welcome. I use this computer for working, and I have a mountain of important information on it.

This issue happened randomly when I was skyping with my friends and playing a game as well. The screen turned a weird black and white lines stretch across the monitor but my call was not affected and same for my game. I could still hear my game and them but couldn't see anything on my monitor.

I restarted my computer in normal mode and logged in as usual. But after a minute my screen turned this weird blue like color (it wasnt a BSoD) and again I couldn't see anything on my desktop being displayed from my monitor.

After restarting again I went into safe mode and waited 5 - 10 mins and everything seemed fine but I restarted to normal mode again then the same blue screen flashed up. I went back to safe mode and scanned for viruses but no threats were found.

I honestly don't know why this is happening so I don't know what is causing this problem.

Answer:Computer Screen turns blue on desktop startup

If it works OK in safe mode we can assume that the screen is OK. I would check the graphics driver.

Answer:Computer screen turns black when playing games

More than likely a faulty graphics chip, the mobile Nvidia 8/9 series which you have are notorious for this especially in laptops with less than perfect cooling which allows them to get very hot.My advice would be firstly to clean the heatsink and fan thoroughly, secondly try a fresh install of Windows with the latest Nvidia drivers.  Trying to troubleshoot an installation that has had a lot of random tweaks and settings applied by a dubious program isn't going to go far.  If you still have the same problem with a fresh install, it's likely the graphics chip is toast.

Hi friends

I have an MSI a6205 laptop, and have recently reformatted my computer to reset everything in it. My problem is this:
Ever since I re-installed Windows 7 my computer has been starting up, getting to the little 'Starting Windows' animation, then the screen turns off completely, with no back light (the fans and LEDs still function perfectly). The way I have been getting it to work is by turning it on, waiting for the screen to turn off, then tapping the power button and putting it to sleep, after a few seconds I hit the power button again to awake it, and the screen turns on and functions perfectly.

I know this isn't a hardware issue, because I also have Ubuntu 12.04 installed on the machine, and it works perfectly. It's just Windows 7 that is giving me this problem.

Answer:My computer screen turns off after the 'Starting Windows' animation :(

Is the power button configured to put laptop asleep (standby mode)? Or is it hibernation?
Default behavior is shutdown btw

Hello! I recently dropped my desktop (I'm soo clumsy) on the floor. It's a dell vostro 400 with 4gb ram, intel 2 duo core, and nvidia 8600GT. I know it's not a power issue. The first time i turned it on after the accident, it beeped continously. Everytime i turned it on, all of the fans start up, my monitor recieves a signal from my graphic card but goes to power save mode, and it doesn't load the bios or the start up screen... what ever it's called. Any way of fixxing this or is it dead? I think it's the motherboard that's as far as i can tell.

EDIT: the graphics card works properly. It fell while it was on; I had to hold the power button to turn it off since it froze.
 

Answer:Dropped computer turns on, but black screen occurs

You moved and dropped the computer while it was on??? Not good. Open the case WITH THE COMPUTER UNPLUGGED and reseat the memory, and the graphics card. Check the CPU heatsink/ fan to make sure it is still tight and positioned properly. Also, check for any loose cables

I recently upgraded to windows 10 on my Dell Inspiron 5720 and I have been getting a lot of lag. When I start up, everything works just fine. However, if I put the computer to sleep or if the screen even turns off when idle, my computer slows down to a crawl. Programs won't open. I have to wait several minutes for the start menu to open and it takes about 10 minutes to restart. Once I restart everything works fine. I am guessing it is a graphics issue, but I don't know how to fix it. Has anyone else had this problem and, if so, were they able to fix it? Thanks!

I was playing around with Task Scheduler to turn on laptop at specific time, it works great. However, while the system starts up just fine, the screen remains black until I touch the mousepad.

Now that doesn't seem like a big deal, but what I was experimenting with is having the computer turn on so I could use TeamViewer app on my phone to access my desktop when I'm not home. Problem is, TeamViewer won't access desktop if screen is black and if I am not physically present, I can't tap the mousepad.

Anyone know why the screen doesn't turn on? It worked great on my old Dell with Vista, system and screen came on know problem.

Answer:Computer turns on, but screen doesn't with Task Scheduler

It's most likely in the power options to turn screen on when computer wakes from sleep. Just a guess.

I've been having an issue with my computer for a week or two now. Figure I'll explain the symptoms first.

First off, it takes a long time for anything to load. This includes when I first start the computer, opening a program, switching between windows, and shutting down the computer.

It also seems to be slow on updating the screen; for example, even now as I type sometimes the screen will freeze. I will continue typing until I realize this, then I have to rapidly click on the firefox button in the taskbar to make the entire monitor blink black a number of times before the firefox window opens again and shows what I had been typing.

The computer also likes to blink to a black screen like that on its own; the black screen only lasts a second or less, and sometimes it will happen once or a few times in succession.

Programs also like to lag; Word for example is impossible to work with; parts of the program will become invisible (showing my wallpaper underneath) or the program will just freeze if, for example, I open the drop-down menu for changing font size.

Even saving an image from the internet usually results in the monitor freezing; though I can usually still move my mouse, click on where the save button would be, and after the screen blinks again it shows that the image did save correctly. The pointer also freezes sometimes as well, though this isn't as often.

I've tried to do a system restore, but all my attempts result in the program saying the r... Read more

Answer:Computer Hangs, Lags, Freezes, and screen turns black

Hi TRM01 and welcome to TSF

I'm assuming you are using a desktop computer. Unplug all external devices except the keyboard, display, and mouse. Boot and check results.

Boot in the Safe Mode and see it the problem persists. Normally tap on F8 at early boot to get the Advanced boot menu. Might be F12. Check results.

Try the task manager long enough to turn some things off. Many things will not turn off, but many will. Watch the CPU usage at the bottom each time to see if you have found an application that is eating up your cpu time. It should normally be very low if you haven't started any applications.
Turn off explorer. Your icons will go away. Restart explorer using the new task under the file tab. Type in explorer to get it back. Any difference? Note that everything you disable will be reloaded next boot.

If you find a task that is causing the problem, you might be able to disable it in msconfig under the start tab using the check boxes. Start>Run> type in msconfig then enter. If you would like to find out what each item does, follow this link:

http://www.sysinfo.org/startuplist.php

If you have some items that you never use, uninstall them, especially if they load something into memory during boot.

Make sure you are using only one Virus Protection program and one Malware program. If more that one is loaded, they sometimes fight each other and slow down your computer.

Open your task manager and see if you have any yel... Read more

Answer:HELP! Desktop turns on and restarts repeatedly, other turns on to black screen

Hi&#8230;.

Desktop 1:

Do you see anything on your screen at all while this is happening?

Have you tried to press the setup key to see if the BIOS will come up and make changes?

Do you have any USB devices (other than keyboard or mouse) hooked up? If so, try disconnecting them and see if it will at least POST or attempt to go into the OS.

WARNING: Before checking the capacitors, disconnect the power cord on your system and press & hold the POWER button to allow the power to discharge! Also, you should always ground yourself before touching computer components to prevent static discharge!

Just FYI, some of the motherboards in this series of HP&#8217;s have issues with the capacitors.

You should take a look at the capacitors to see if the tops of them are raised or discolored. Also, if you put your finger on the top of the capacitors, they should feel as if they are INDENTED and not flush or raised. Raising or discoloration (up to and including a black tar looking substance on the tops indicate a leaking capacitor).

Desktop 2:

Any POST sounds (beeps) produced at all?

Have you tried the monitor from Desktop 1 on this one?

Anything at all displayed on the monitor, to include CHECK CABLE message?

Recommendation: Open the case again and ensure that all the cards, memory, drive cables and so forth are all connect properly and not loose or dislodged.

Do you know how to RESET your BIOS to default using the onboard jumpers?

Answer:HELP! Desktop turns on and restarts repeatedly, other turns on to black screen

For system #1 the problem could be from one of several like a weak battery on the board itself not maintaining cmos information or even worse "bad caps" or a failing bios eprom chip for just two there. Bad caps being bad capacitors on the board like one or more leaking or bulged out. Look for any discoloration on the board itself.

For system #2 you may have accidently blasted with too much force against the video card seeing that now raised up in the slot. Any high power dust blower is never recommended for use inside any system. This is why there are cans of compressed air called air cleaners that gently blow dust and debris out of a case.

Hi,I'm having trouble with two of my desktops.Desktop #1 Problem:When all cords and such are plugged in, I press the power button. The desktop turns on for about 1-2 seconds and then restarts. The bios doesn't flash, the os doesn't boot. As far as I can tell the desktop restarts indefinitely. Any ideas what's going on here?--Desktop Type: HP Pavilion a705WI found someone with a similar problem hereDesktop #2 Problem:I bought some 3M Dust Remover a few days ago. I disconnected power, along with everything else, from a desktop of mine. Pulled the cover off and started blowing the dust out of the case. I put everything back together, plugged it in, and the desktop doesn't work. It boots to a blank screen with the the power and hard drive led's stuck on, on the front of the desktop. The led on the back of the power supply turns on, I can hear the hard drive spin up, it detects the cd/dvd drives, floppy drive and then just hangs with the led's stuck on. Anyone have an idea what might be going on here?--Desktop Type: Compaq Presario S4200NXThanks for the help, I'm hoping to get atleast one of these back online w/o buying a whole new desktop.-Chris

So I ve encounterd this issue while im playing video games (mostly Tera), in the middle of the game the computer screen goes black (sometemies even other colors), but my computer is still running, although my Hard drive indicator isnt blinking.
I have a:
Intel core i5 3570k, Asus gtx 770, 8 gb of ram, 1TB HDD, 650W Psu,
I dont think its because of overheating, because when i look up the temperatures the max on my gpu is 75? on full load what is fine for the 770, and my cpu is on full load at about 54? max.
So could it be a software problem or my HDD is not working properly.
If anyone could reply i would be thankful.
Thank you!
