Computer won't boot - blank screen!!

Question: Computer won't boot - blank screen!!


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!").

The only thing that I think it could be is the CPU or motherboard but don't see how and I don't want to go out and buy anymore because I am poor (!!!) but will do so if I have to. I'll take it to a repair shop if needs be but I hate doing that because of male pride or whatever (i've built a lot of computers and managed to solve the problems that have come up with all of them so far).

Also, as I can't tell what's going on because the screen is black I got on my friends computer to see if my files were still available on my home network...they are not. I thought that atleast if I can get to my files then I know it's something like my graphics card or even monitor causing the problem, but like I say, that doesn't work either.

PLEASE PLEASE PLEASE throw me some ideas i'll be really greatful.

Preferred Solution: Computer won't boot - 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 (This link will automatically start a download of Reimage that you can save to your computer.)

A little more than a year ago I built a decent computer (with your help. thanks!).
A couple of months later the computer mysteriously stopped working and the only sign of life was a lamp glowing on the motherboard. The fans also spun for less then a split second when trying to power the computer for the first time after plugging in the power cable. I figured it was either the motherboard or the CPU, but I didn't have the time or the money to look into it back then.

Now, more than 6 months later I've found the time and some money to try and take care of it. Yesterday I tested some parts and bought a new motherboard. After installing the motherboard, the computer will turn on, but it will turn off after a few seconds then turn back on and remain that way until i turn it off manually. During that time my screen remains black. I've tested all components except the CPU now so I'll probably have to buy a new one. But I have a few questions before I do that.

First off here is my Specs:
1x MSI Twin Frozr II GTX 580
1x Corsair TX750
1x Intel i5 2500k with stock fan
2x Gskill Ripjaws X 4gb
1x Samsung SpinPoint F3 HD103SJ 32MB 1TB
1x NZXT Hades case
the new motherboard I bought was: ASUS P8Z77 LK
and the old one was: Asus P8P67 Pro B3

Do you think there is anything else that might be causing my problems? I've tested the ram, Graphics card, Psu and Hdd on another machine and they all work. I've tried putting the ram in different slots with the same result as earlier. I've trie... Read more

Answer:Computer won't Boot, Blank screen

Have you tried to setup the system out of the tower. You could be getting a ground out. Just find a box to set the motherboard on and put on your video card ram CPU and power it up.
You will need to cross the two power pins to fire it up.Try with just one ram stick if you have two then try the other. after you try that and if you still have no luck. take off your CPU fan and put your finger against the CPU chip and fire it up for just a few seconds to see if the CPU starts to heat yo. If it does you still have voltage going to the CPU and it no doubt is still good.

Hi all,

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.

I'm horrible with computers so I don't really know anything about my computer except that it's a Dell Dimension E521 and has Vista Home Premium..

My problem is that when I start my computer, after the BIOS loads and where it would normally go to a log in screen it just stays a blank screen (no cursor or anything.) I tried loading it in safe mode and it just freezes at "crcdisk.sys" and I also tried using system restore which says "the disc OS (c:) has errors) and tries to repair it (to no avail.) I also tried the "Repair Your Computer" thing and left that running for about 12 hours and that didn't do anything and so I finally tried to reinstall Vista but I couldn't even do that (the disc loads and lets me click install but it freezes after that.)

I guess I should say when my problem started.. I clicked a youtube link and then some error came up saying (I don't remember but it did say something about C (not the disk but the code)) well after that error Firefox froze so I tried closing it (through the task manager) but it just said access denied so I tried to restart my computer but explorer was frozen so I had no choice but to use the power button after which my problem started..

Also in the system settings error log it says there's a POST error Keyboard error every time I try to restart my computer..

I have Windows XP Home installed on a Mesh computer. Everything was fine until recently but now the computer will not boot and there is absolutely no indication on the monitor. I plugged the computer into a friend's monitor and still there was no indication that the monitor was picking up a video signal (the amber light did not turn green and the screen remained blank). I then installed a known good video card but that gave the same result. I installed another HDD, changed the motherboard battery and got the same result. The computer will not autoboot from a bootable CD (and I can't get access to the system configuration menu). The fans are running and so there is power to the computer.

Any ideas what is wrong and how I can overcome the problem?

When I turn my computer on it goes to the blue hp logo and then to a blank screen with a blinking cursor in the top left corner. If I hit f8 when booting it gives me 2 options...f1 to setup and f2 to resume. It won't let me go into safe mode or anything. I have tried booting from the xp cd, but nothing happens. I have tried replacing the battery and that hasn't done anything.

It started when trying to open a program, the computer just went blank. When trying to reboot, this mess started...

I'm going to assume my processor went out on me here, or motherboard.

I usually leave my computer on overnight and woke up to find it off the other morning. I turned it on, fans ran, power light and HD light was on but my screen was blank and in screensaver mode. I shut down and tried again a couple times and after the second or third time I had no power at all.

Thinking my PS was bad I replaced that but had the same outcome as above. I then tried a new video card and had the same outcome again.

Gigabyte 945P-S3 MB
Processor, can't find the paperwork but it is a core 2 duo processor, possibly 2.93GHz but it's 3 years old so maybe slower.

My processor heat sink was pretty loaded with dust so assume I burned it out. I seem to be pretty limited on inexpensive replacements but may try a Pentium Dual Core E6500, not too expensive but I'd hate to be limited in MB's if that is gone.

I put in a cheap 400w power supply to check that, then a Gigabyte HD 6450 video card.

I did pull the processor, all ram, reset everything but also took out the MB to look it over, no signs of burning.

I did try booting up without the floppy and CD drive, same result, as well as swapping ram to different locations, no change.

What should I look at next?

Answer:Computer won't boot, fans run, blank screen, screensaver on

If you do decide to get a new processor, make sure they have a decent return policy if it ends up not being the cpu but the mobo. The E6500 is sort of dated but they have a good price right now. I was looking at them just the other day for a cheap backup unit to replace my 1.8 northwood P4 system.

Yesterday my PC was working perfectly. No new drivers, updates, components or software have been installed. Recent virus scan was clean. Seemed to shutdown fine. However, I turned it on today and now it takes 41 minutes to boot up!! Heres the sequence of events:
23.35PM - Turn on PC. The monitor comes on, motherboard makes a beep, and displays the POST (Power On Self Test) as normal, then a dash _ blinks a few times in the top left corner, after that the monitor just goes completely blank (not even a cursor).

00.14AM - Finally the Windows loading bar appears. Longer than usual delay before the Windows circle icon appears, but from here everything appears to load fine.

00.16AM - Into Windows.
Ive reset several times and it always takes this long (even in safe mode). Though once in Windows everything runs like normal, no errors, no corrupt files etc.

Heres what Ive done so far to try and fix it: reset bios to default, took cmos battery out, removed all peripherals apart from keyboard and mouse, tried different keyboard and mouse, using different monitors, removed soundcard, checked connections, checked fans, tried different graphics card, run virus and spyware scans (clean), defragment, scandisk, registry scan, hard drive health checker, checked boot order.

I had a look myself and can confirm that something is wrong, i asked if she had accidentally pressed any keys on the keyboard i.e FN+screen off and she said she hadnt.

I plugged it upto my tv using the VGA port both at boot and after leaving the laptop 10 mins and nothing, the laptop is booting, you can hear the fans and harddrive and the lights on the front are all giving a positive response but as above the screen wont turn on.

Try to start notebook with AC adapter only or with battery only.
Disconnect both and leave it for a while and check if the same will happen again.
You can try to remove HDD and see if notebook will starts properly (BIOS and Toshiba welcome screen).

This problem started just last night and I've gone through a series of possibilities, and I'm pretty sure I've ruled out it being the Video Card, at this point I'm assuming it is the Hard Drive, but I wanted to get an opinion that has actual value rather than my own >.<

Last night I shut down my computer via start menu and went to turn it back on and when I did the screen went blank/black after the "boot menu" (not 100% sure what that menu is called, its where its kind of blue (i have an hp) and you can hit Esc, F9, F10, F11). After that happened I figured oh well maybe it just loaded wrong, so I shut it off, now when I hit the power button, rather than having to hold it down, I just press it once even lightly and it just shuts down completely. Normally when you hit it you have to hold it down to shut it down completely (or so I think).

Now I'm currently using an 'Nvidia GeForce GTX 260' video card, I swapped that out with a working one which was an 'Nvidia GeForce GT 520', not 100% sure if the 2 were compatible or not, but it fit and everything ok. Computer still did the same thing with the other video card. I didn't try the current one (in the broken computer) in the working computer, to rule it out completely. I just assuming that was the cast, besides it wouldn't fit in the other computer, or didn't have some of the cords.

Answer:Problem with computer going to black/blank screen after "Boot Menu"

See if you can boot off something like Hiren's Boot CD and then run a hard drive diagnostic tool.

That will rule in or out a hard drive problem. It could be that your Windows system files got corrupted and maybe you could fix by doing a repair of Windows from a Windows 7 dvd.

Someone told me this is going to be a hardware problem? Just in case not, and it is software related, please direct me to the right person? I am also currently running the thread for some bad trojan I picked up

In safe mode, the last line before boot-up freezes:


I have tried the option of "last configuration of functional settings" and nothing.

My battery seems to have been fried (only ever gets to max 70%) and I thought it might be due to a power surge. To check, I let it run down last night, to recharge it this morning and see if it would charge fully. I was watching a tv series on vlc, and everything was functioning as "normal" apart from the usual issues the trojan would dole out...I was completely surprised and utterly disappointed to find that this morning I have NO computer at all, while I have been patiently waiting for the team to help me axe this damned virus.

I have here my Mother in Laws C670-14D and its developed an issue whereby when you power up the screen is blank. it does have backlight and you hear the windows startup sound that you get before you login as windows starts up.

I can see the screen if I start in safe mode, in fact I'm using the PC in safe mode as I type this.

I did hae a similar problem in the past with another Toshiba laptop and that was windows 8, the issue was connected with power save settings but I've tried all of those and no luck. Also tried the remove battery suggestions, nothing has worked.

I'm guessing windows has done an update that is causing this but I'm at a loss and google has turned up nothing.

I?ve got two different Toshiba notebooks at home and never had any similar problems with my units.
In my opinion your notebook?s hardware seems to malfunction.
It?s hard to say what could be wrong because nobody here could test your notebooks hardware parts.
First of all the RAM modules should be checked. If the modules are ok then an motherboard itself or an part on the motherboard could be affected.

It started booting up again and when it finished Windows logo screen, it went blank and no display with all the other lights were in correct status. I waited for a long time before attempting a reboot. Since then i don't see anything on the screen after the initial BIOS screen (Which is also all jumbled up).

Bonjour mes amis.

I recently have started getting the infamous black screen of death at my computer's startup, very similar to this fellow user's problem. Basically, Blank screen on boot up, before login screen; slow startup. The black screen lasts at least two minutes on average, before the windows login screen comes up. Everything else runs fine!

I think it might be my antivirus, Bitdefender Total Security 2013, and I've posted on their forums about it, and I've gotten responses from other users saying:

The Black screen issue is known by BD Support till now they have not able resolved that issue.
hope BD 2014 resolves the issue.

And the booting time issue is been solved.

However, I uninstalled Bitdefender and the problem still persisted. I proceeded to uninstall every program i could remember installing before the problem started, so before the start of June. This was painful because I updated all my software, so everything was listed as installed recently.
My startup time after removing all these software is attached below; 156 seconds, compared to before with the speed ranging from 200-500 seconds, with the worst at 472 seconds.

Although this sped about my startup, I still got the annoying black screen issue. I am sure it is a software issue because the black screen is present, but lasts no longer than about 5 seconds when starting in Safe Mode with Networking, and is present even int he low graphics.

Nothing appears on the screen when booting the computer from a powered off state. Not even the Thinkpad spash screen appears on the display when I press power. The backlight appears to come on but the display is still mostly black. So the LCD cables are at least partially connected. I doubt it was related since it was a driver, but the last thing I did in Windows was update the Wacom drivers since the pen was not tracking correctly in slate mode. This is what I triedPressed Fn+Home a few times then Fn+End a few times. The backlight increased in brightness but the display was still mostly black. Pull the AC power and the battery. Press the power button a couple times to discharge lingering charges in the capacitors. Installed the AC power only, then pressed power. Still nothing. Powered up the system then pressed the blue ThinkVantage button immediately.

Answer:X220 blank screen at boot, not even POST spash screen

You should've gotten beep codes when you booted without ram.  That's not a good sign.,
There isn't any key code that I know of to reset the bios without actually being in the bios.
The old procedure for ThinkPads was to take out everything that is in a slot, hard drive, RAM, wireless card and modem, battery and unplug the ac adapter and hold the power button down for 30 seconds and then put just the ac adapter back in and push the power button and see what happens.  If you get beep codes, put 1 stick of ram in and hit the power button again.  If nothing, take out that ram stick and put another one in and try it again.  Try it in different slots.  See if the bios splash screen comes up.  If it comes up, start putting components back in one at a time and rebooting each time until it doesn't.  Save the hard drive for last.
Are any of your indicators lit and does the fan come on when you hit the power button?
It sounds like you already tried most of that, but that's the only thing left to try that I can think of.

Hey, first time posting here, so sorry if this is the wrong section or anything.

Lately my laptop has been experiencing a problem when I boot it up. After the Starting Windows screen with the glowing Windows logo, a blank black screen pops up that lasts for ages (I'd say at least 5 minutes). Afterwards the login screen will appear as normal.

When I log in, the desktop appears quickly, but when I try to start any programs, like my browser, they are slow and freeze often (usually I can run programs with no problem when the desktop appears). Sometimes the laptop will hang every three seconds. It takes a bit of time before the programs and the laptop run like normal.

I've tried several things without success:
-Uninstalling and reinstalling graphics drivers (I've never updated my drivers because no updates are ever available for my driver; is that normal? My laptop is about two years old)
-Defragging hard drive
-System Restore (I don't seem to have any restore points)
-Clean bootup
-Startup repair (or whatever that first F8 option is called)

Started in the beginning with me booting up my computer. And no live screen occuring. ie. Monitor is on but goes to sleepy mode. (orange light instead of green light). I'd have to boot again before it'd run. However, now no matter how many times I boot it does not cause a live monitor. I bought a new stick of ram. PC3700 400 Mhz. Even though my MO takes up to 333 Mhz but that should be okay as it'll just bump it down. I also reseated my graphics card and changed the slot in which my RAM was in.

If I reseat the graphics card the computer will cause a live screen, but crash shortly after with a computer freeze. And I'd have to reseat everythign again before I'd get another live screen. Usually holds long enough to load windows and get in for 2 minutes before freezing.

When the monitor does not become live, there are no beeps. When the monitor does show (before the freezing problem) the mo beeps once. Hardrive, fans on power and graphics card all work. mother board light is on. No weird sounds. Monitor does work as I've tried multiple monitors. I'm running out of ideas, Suggestions?

Answer:Blank / Black Screen on boot usually and when it does boot freezes

Looks like something is up with your graphics card. Try the onboard monitor output (if you have one) or another graphics card. Hope this helps.

I have a Win XP Home edition that fails to boot; the POST screen loads, then a choice of operating system configurations (see later), and selecting  one of them (the last on the list) returns can’t find hal.dll.
The other two options, one of which I have set up in the course of trying to sort this out, both end up with a blank screen.
Safe mode hangs up in the middle of the driver list.
The problem started after a power cut.
I have fairly exhaustively investigated and tried to fix this as follows:-
Seagate 250Gb disk in four partitions, C,D,E,F. Using a partition tool confirms that the active and primary partition is C. The files on all the partitions are all visible using file explorers on bootable recovery CDs (ERD Commander and HIRENS). I have been able to back up the important data. The operating system files are on C partition only.

Hi everyone,
I have a friend's Dell Inspiron 15 Laptop. It can't boot into anything. I have tried using a Windows USB stick, but it just goes to a blank screen. Even automatic repair won't boot - It just says preparing then fades to a blank screen!

Is there anything that will fix this?

(P.S. I have not tried a Windows DVD, as I don't want to buy one unless there is a good chance it will boot.)

Answer:Blank Screen after Boot

Can she boot up into safe mode?

1. See if she can. This is how:

If safemode loads, then there is possibly either a process or startup program that is causing her computer to hang.

Next, you will want to use msconfig to par down your startup programs and services.
See this article on how to do it:

Answer:XP Won't boot- blank screen

Download and burn to CD one of the Kanotix Live CD os's then use it. From the running live cd you will be able to tell if your hdd is faulty. It is not rocket science so you should be able to do that.

Report back when you know for sure if your hdd is working or dead.

You could use any GNU/Linux Live CD but Kanotix is easy to use for a newbiee.

I been having problems with my graphics card for sometime. It will hang when i am playing games occasionally (fifa 08) and also when i am viewing videos in youtube/yourfilehost it will randomly hang, and when i am boot up everything is ok.

Today, it hanged after entering windows and whilst loading the start-up problems and now it can reboot properly.

When i start the computer, it shows the screen where i can enter the bios, but it doesnt load anything thereafter and the computer is just idle with the monitor power button in still 'green'. I would think its a VGA card problem.

Motherboard: ASUS M2N-E

Answer:Blank screen after boot-up

Since your monitor light is 'green' there is a signal from your HDD and I believe that you need to get a better GFX card. I did read a few reviews of that card and the general word is it's not really a gamer. I think it has been deteriorating: now it's at the point where it won't work at all: even just to give you a Windows program video. I don't know how much ram that you are running but if you do upgrade your card (I think that you have to)...make sure you have at least 2 gigs of ram. It's really cheap now. Make sure to buy a ram model # that is on your motherboard's compatibility list.

Answer:Blank screen at boot up

Now after a little over 2 hours the screen waked up again.

The screen was not black, but silver.

The graphics card is a NVIDIA, where I have the VGA connected to one monitor, and
via a DVI to VGA adapter another monitor is connected.

I have encountered, that something is slow, and I have seen it a while.

The DPC is ok, and also the CPU load measured with Process Explorer.

On power up my screen occasionally is blank .i.e. no Widows boot information. However, I can hear the hd going through its boot rituals.

Sounds more like the monitor. If your graphics card is disconnected or u/s, you usually get a message on your screen to the effect "check your video input" or something like.Do you get any "white lettering on black background" on the monitor during initial stage of boot?Forget px unit if fans/drives are still working.Check all connection to your monitor and don't connect/disconnect mains WITHOUT powering down Windows (press and hold the PC ON button until everything stops).

I was recently having trouble with a dll file crashing Star Citizen. I tried a million different things to try to fix that, and none of them worked, including the installation of a bunch of older and newer drivers. I eventually tried replacing the dll file itself, but that caused a different error. After that, I was unable to replace the file back to the original.
I decided to try Safe Mode, because I planned to completely uninstall my old drivers and do a clean installation of new ones (BTW, I was using Windows 7 64 bit and I have Nvidia GeForce 560 Ti running driver version 331.65). However, tapping F8 caused my PC to not finish booting. It would go from the black, monitor-off to a blank navy-blue screen. That is, the monitor would come on, but nothing else would load.
So, I tried to force my PC to start up in Safe Mode. ...And now I'm eternally stuck on that navy-blue screen. Nothing loads. I have to force shutdown my PC to get it off. I've tried starting it up and tapping F1, F2, F4, F8, F9, and F10 upon start-up (each separately and waiting at least 10 seconds between attempts), but that did nothing.
If anyone has any suggestions or if it appears I should just go ahead reinstall Windows, I'd really appreciate the help. Thanks.

The fan goes on, the lights flash, but no picture. I've researched the problem and tried all of the troubleshooting tips to the best of my ability: checking the power source and cable connections (they're good), testing the monitor by hooking it up to the new computer (it works), pressing F8 to try to get into safe mode (I can't), and opening the computer to ensure that nothing slipped out of place during the move (something seemed a little loose, so I pushed it back in). But I still haven't been able to resolve the problem. Any other suggestions? The computer is running Win95 if that helps.

Yesterday, when I woke up to start up my computer and press the power button, the comp tried to start up for about 2 secs, with the HDD light flashing... then turned right back off. I was puzzled at this and proceeded to troubleshoot. I cleared the CMOS and checked all the cables and tested the RAM... all turned out fine. Then it actually proceeded to have it stay on and everything and all the fans were running and whatnot. Then I disconnected the HDD and suprisingly, it finally allowed me to get to the BIOS and I changed a couple settings. Then reconnected the HDD and everything was peachy keen.
Flash to THIS morning.... the same thing has happened. Except this time, with the methods that I have tried, it is not working.

If the hard drive is original to the dell you can do a factory reset by holding the Ctrl key while tapping the F11 key at power up. This will start the Recovery Manager. If that does not work, you should be able to reinstall XP using the Dell Setup disk.
The problem with XP is it is no longer supported by Microsoft with Security Updates. I would not do any banking or online purchases with a XP computer.

So I thought I had fixed the problem but when I went to install Windows on the new PC I built tonight I only see a blank screen. I don't hear any beeps from the motherboard. I've tried useing just 1 stick of ram, in both slots. I've cleared the CMOS and taken out the watch battery and put that back in. Checked all my connections and made sure they were good. I've ran out of ideas. Also, I have the motherboard outside of the case, but screwed onto a motherboard tray that slides into the case. Wanted to bring that up since I read something about a bad ground in another thread. I've got a DFI board, so I'm useing the button that's located on the motherboard to turn it on and off.

Also, about 8 hours ago I had the system working, and the Windows XP CD was in the drive and it booted from it. When it got to the main menu I opted to exit the installer, I had to go to work and didn't have time to finish the install. Then it gave me 10 seconds or so to restart and when it restarted I held down the power button and shut the system off. Don't know if this has anything to do with it not working, but I thought I should include that information.

Its possible that this sis driver or software related, if you boot into Safe Mode (F8 at boot) does your PC boot ok?

What you could try is to disable all startups using msconfig (click start and type msconfig into the start search box and hit enter, then click the startup tab and click disable all) then reboot and does your PC boot OK, if so enable one at a time until you find the possible culprit and let us know which it is.

In Device Manager do you have any yellow ! marks by any devices? if so what?
Also are all your Drivers, Windows 7 ones, or did you have to install any XP or Vista drivers to get any devices working?

Windows XP SP3 on a Dell desktop. More info upon request.

Last week I caught some malware on my desktop. I recognized it and ran rkill and malwarebytes, but noticed the process that had been working for me forever wasn't quite getting rid of everything. So my first move is to try to get into safe mode and get to work. Sadly, every single method I took to get to safe mode failed. I first tried the F8 method, which prevented me from getting past a blank black screen; no noise; no sound; no signs of life at all. So I held down the power button and let it start up normally, which it did fine. Then I tried using Superantispyware's Bootsafe application to try to get SAS to do the work for me. Once again, blank screen, no signs of life. Again, hold power button down and restart normally and everything's fine. So I try the third and last ditch option, check off bootsafe in boot.ini via msconfig. Now no matter what I do the desktop refuses to get past a blank black screen. The power button turns blue, the fan turns on, I hear a single beep, and then nothing else happens. N-O-T-H-I-N-G.

First off, I'm fairly ignorant about computers.

Does anyone have any ideas as to what might be wrong with my hard drive?

Won't boot, will work as slave.

I clicked a shortcut to Firefox and the browser window opened but froze before the homepage had loaded.

Cntrl/Alt/del didn't work so I pressed the little reset button.

I heard a beep, then saw the first page of white text (checking for memory size and offering the option of pressing Del or F11, etc). This page of white text disappears after a few seconds and is momentarily (0.2 of a sec?) replaced by some more white text (too fast to read).

Then the monitor goes black and nothing else happens. No sign of the Windows XP startup page.

I tried a few times.

I took the hard drive out, removed its jumper, and connected it as slave in an old pc. I was able to access the drive and backup my most important files. And before everyone has a go... I do usually back up to an external drive, but the missus had problems with her Mac and has swiped my backup drive. I know, it's shocking, she just plain nicked it. Reformatted and everything. Sheesh!

I'm thinking about trying a repair from the disk (if I can find it). But is doing this likely to remove any files? I can't try replacing drivers as I can't get the pc on.

Answer:Blank screen during boot up

Insert the Windows XP CD into the CD drive, and then restart the computer. Click to select any options that are required to start the computer from the CD drive if you are prompted. When the "Welcome to Setup" screen appears, press R to start the Recovery Console. If you have a dual-boot or multiple-boot computer, select the installation that you must access from the Recovery Console. When you are prompted, type the Administrator password. If the administrator password is blank, just press ENTER.Type: chkdsk /rIt's important to have a space before the "/".To exit the Recovery Console and restart the computer, type exit at the command prompt, and then press ENTER.

I have an Acer Aspire 5315-2326 laptop ... 1 gig ram running Windows Vista Home Basic.

I have had it about 3 years. No really serious trouble until now.

It will boot completely through to Windows, as far as I can tell, quite normally. The problem ... I cannot keep the screen image on screen for more than about 7 seconds before the screen goes blank. No cursor, nothing. To see the screen again I must hold down fn (function) and depress f6. At that point I get a part of a second to 6-10 seconds of the screen appearing normal. Then it goes blank again until I once again depress fn+f6.

Interestingly the PC manual indicates fn+f6 "Turns the display screen backlight off to save power. Press any key to return."

Any help appreciated. And thank you.

Answer:blank screen at boot up

Hi rhoadesbThis might be a problem is most often caused by a faulty screen inverter. What this means is that the screen itself works properly, however the backlight does not function properly.However, for this to be true the screen itself has to be working, its just that it is hard to see because of the fact that it is not lit. An easy way to check for this is to simply shine a flashlight on the screen. If you can see the desktop even though the screen is dark then it is the inverter. If you cannot see the screen at all then you have a different problem.If you cannot see the screen after you boot into Windows, then it might be a driver problem. Try booting into Safe Mode and seeing if you run into the same problem.Also try going into the BIOS (Press F2 while booting) and see if the screen stays on while you are in the BIOS.Hope that helps!

Hey i recently reformated my computer today just to clear it up with unwanted stuff so everything went smoothly, then as i was installing programs back onto my computer i had to reset it so now everytime i boot up my computer it gets passed the bios screen then after that it just goes blank, i cant get into windows no matter what i do. I tryed going into the bios settings and changing the boot devices but that didnt work. I also then decided to just reformat it again, so i put the windows xp cd in the drive, and when it says press any key to boot from cd i hit any key and it goes to a blank screen again.

Just wondering if you could help me with this problem I've been having with my computer for the past two weeks or so.When I first turn on my computer it will go through its usual DOS rigmarole of loading what it needs to load and then... nothing. The screen is blank. No mouse arrow and the keyboard doesn't do anything. I can't re-start so I have to literally turn off the computer, turn it on again and, of course, get the message that I did not shut down correctly before and that I have to boot up in Safe Mode.After going through all the tsuris making sure everything is working OK in the Windows Device ManagerI am finally able to re-start and get a working screen. But then I have to reset my monitor display and re-organize my screen icons.This, as you can imagine, is very annoying. The past couple of times I just bypass the safe-mode by punching in numero 1, Normal Mode, which happily brings up my properly set windows desktop. But of course this still leaves me with the anxiety of what's happening to prevent me from seeing this screen the first time I boot up.Any advice will be greatly appreciated.

Answer:Blank screen on boot?

Open SYSTEM CONFIGURATION in Administrative Tools. Make sure that under the GENERAL tab, you have NORMAL STARTUP dotted. Under the BOOT tab, nothing should be checked. Change the TIMEOUT time to a lower # if you want to decrease the time Vista waits on you to do a boot option. (ex:Safe mode, boot from cd, etc...) I use 15 secs. To short & you won't be able to hit the key fast enough.

Hope this helps,

I've had this problem for about a month now. It started when I put in a new Processor a few weeks after my old one died. When I turn the computer on, with the monitor hooked up to my Video Card, the screen stays blank until it reaches the Windows Logon Screen, then it is fine. It is the opposite with the onboard, it will turn on through the boot until the Logon Screen, and then it goes blank. Appreciate your help in fixing this! Thanks.

Answer:Blank Screen Throughout Boot

I think the screen frequency has been somehow set up incorrectly (during bootup)

You could try downloading the most up to date drivers from your Video card's manufacture's support page
Then fully uninstall your existing drivers
Then install the newest drivers
Then restart again

I hope it works

Answer:Blank screen at boot up.

Could be a bad power supply. Just because the fans turn on and everything sounds okay, doesn't mean the power supply is good.

Other possibilities are bad main board, bad video card, bad memory among other things.

Also, to turn off a computer with the power button, you have to hold it for about 5- to 7 seconds.

Answer:blank screen when win xp should boot

Sounds like a cable problem, seeing as it wont boot with the XP disk (assuming you set the BIOS to boot from CD). I say this beacuse a lot of systems have the Cd/DVD on the same cable as the a cable problem can cause those symptoms. Anyway, just pull the cables out and reseat them, and try again. If that fails, my guess is that you have an O/S failure.

Try the cable first...if it dont work, come on back.

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?

So I've been a Seven use for a few years now I regularly reformat my system, not always needed but I like a fresh start every 2 or 3 months, anyway since my last format (I tried Win 10, Nope) I've noticed when I'm starting or rebooting my PC I get my MoBo info and then the Windows Logo comes and goes, then it just goes off for a few seconds I say the screen goes blank, this isn't totally true, it goes to the "No Signal" screen for I guess about 15 or 20 seconds and after that it gets to my log on screen.
Very strange as has never happened before I used to get great boot times but this has killed that, I know its not a huge issue but I'd really like to get it solved and have my quick booting PC again!

I have checked boot sequence is correct but thats about as far as I can go on my own lol, I guessing it may be something to do with the Onboard Graphics in the 4790k & my GTX 970 maybe something doesnt like something else (tech speak) but I have no idea how I would proceed with troubleshooting and getting if fixed!

Any light shed on this would be great,

Many thanks for reading

Answer:Screen goes blank for a few seconds during boot

It seems to be fairly normal for there to be a short loss of video just after the Windows logo, but 15 to 20 seconds, and the "No signal" message seems a bit odd.

If I recall correctly, that little space is when the video and other drivers are loading and/or finalizing their setup, and the computer is deciding what screen to use. I have read that the GPU actually scans on of its ports on startup, and that is what causes the screen to go blank for that short period, as the GPU is sorting out which screen to use for the primary monitor. It doesn't matter how many screens you have, it still goes through the check.

I would start troubleshooting by making sure that all of your drivers are installed and up to date. Check your Device Manager screen to see if there are any yellow triangles. Those might be slowing down your boot.

If those check out, we can move on to the Event Logs.

Answer:w500 cant boot blank screen. help.!

you probably have a W500 with a detaching ATI GPU, you have to run it in Intel GPU mode through BIOS, otherwise it won't work. Take off the keyboard (but don't disconnect the cable, also remember to discharge any static electricity from body by touching a bare metal surface and don't wear any nylon/acrylic clothing), and put some pressure on the ATI GPU part of the heatsink, then boot the laptop up. Try to get into BIOS and change display to integrated GPU.

Hello. My Windows 7 will not boot to my desktop for me like it should or even the login screen. I turn on my laptop, It loads up normally, then I get the blank light blue screen with my mouse cursor and that's it. Nothing else happens and I am not able to see the login screen. I have a Acer Aspire 7739Z-4605. I just backed up my original hard drive to an external hard drive so I saved my information. Once doing that, I did a 'restore C Drive to it's factory settings' operation on my laptop with the Acer Erecovery Management tool and that seemed to erase everything. I booted up my laptop again and ran the Windows 7 install manually on my system and it seemed to work, but even after the install said it was finished I still could not login at all and received the blank screen with my mouse cursor. I have tried a lot of suggestions and nothing has worked thus far. I didn't have the best help with the Acer customer support as they basically hinted for me to just send my laptop in so they could work on it and ultimately make money. So I thought I would try here.

I have an ASUS A7N8X Deluxe motherboard, 2600+ XP AMD processor, ATI Radeon 9500 Duel Pro video card, and Samsung SyncMaster 215TW flat panel display. After dealing with support for ASUS, ATI, and Samsung all blaming each other for the problem I solved it myself.

Problem: After the display had been working fine I was getting a blank screen at boot up. I tried everything all the support sites said, ?Disable USB support on motherboard, powered on the display before computer, updated all drivers.? I was only able to get the display to be detected by using the DVI-I to VGA adapter. Only once in a blue moon would the display be detected using the DVI-D cable.

After resetting my bios 30 times, reseating the video card 10 times, and testing all the ports on my display and video card, hours reading the support forums, I figured it out. When my display was detected the EDID information for my display frequency was 75Hz though Samsung reports it to be 60Hz when run at 1680x1050. My motherboard?s default bios setting is auto and does not have 60Hz. Samsung support told me to low the refresh rate in Windows when the display was detected WRONG. I would not get the port to detect monitor. If I set the bios to 50Hz for the AGP bus the computer would not boot. Then I set it to 66Hz the next setting no boot. Then I tried 75Hz the computer booted but the display was not detected. Then there was some information on a support for DVI problems with DVI-D cable and voltage levels. With... Read more

I have a 4 yr old HP Pavilion p7qe (aka, p7-1380t) desktop. It was working fine running Win 7 until I upgraded to Windows 10 (upgrade potentially unrelated to its current issues). Upon updating Windows 10, the computer got into an infinite booting loop (WDF_Violation). I turned the machine off for a week and when I came back to try and address the software problem, there was no video on boot up. I exchanged video cards with another machine, no change. I returned the original video card (it worked in the other computer). I then removed the memory (2 x 4 GB) and received 5 beeps at start-up. I tried putting the memory back in, one at a time, into each slot and still observed a black/blank screen. I purchased new memory and installed it. On booting, I had video and the booting loop started, but on a single reboot I am back to a blank screen. Any ideas on how to proceed?
