screen goes black; cant shutoff com

Specs: windowx xp home, 512
I will be happily using my computer, then out of nowhere, the screen goes black, as if I've shut off the monitor (but the monitor power light is on).


Also, the computer's power light is on, but pushing the power button doesn't get the computer to shut off. I have tried holding the power button in for 5 seconds, and that can get the computer to turn off. Under normal circumstances, the computer can be turned off with thepower button, and you don't have to hold it in for any longer than a second.


When I reboot, the welcome screen stays on a few seconds longer than it should, and of course I get the 'recovery desktop' thingie, saying that windows experienced an unexpected error, and click here to restore my active desktop, etc.

The problem is, it keeps doing this. Screen going black and can't turn the computer off with the power button, unless I hold it in for 5 seconds. Computer essentially 'dies', until I reboot.


This just started happening this morning. It may be relevant or a coincidence, I don't know, but I had to remove 'vundo' and some other crap (trojans, rootkit, etc.) that was redirecting my browser and causing alot of popups last night.


Does anyone know what might be causing this?


I don't know if it's a hardware issue, software issue, operating system issue, or what. So please don't scold me for posting it here. I really am clueless as to what is happening. :-(

I have an intel celeron m, 512 mg ram, and a 150 GB hard drive. This is a HP Pavilion s7210n Slimline PC.


Thanks for your replies.

Does this happen randomly or when you are stressing the computer? This sounds like a hardware issue to me. Possibly Graphics chip overheating or dodgy RAM. You can check the temperatures by booting into the BIOS screens and checking there. If the insides of your case need a cleaning it will probably be running a little hot even at idle. Watch the temps in the BIOS for awile and see if they elevate.

I had a problem with my desktop always asking to "restore active desktop" until I ran a virus check in safe mode and it found a trojan on my desktop in an .exe file I had downloaded from a website. have you tried running a virus scan in safe mode?

Have you checked to see if you have hibernation enabled? If so, I would turn that off.
Also in power schemes, I have everything set at never.
Hope that helps

Hopefully my advice will help you...Please post back with your results....thanks

FYI, it's normal to have to have to hold the power button in for 4-5 seconds if windows is running.

If windows is not running, then it's normal that just hitting the power button will shut down.

It happens every time I turn on the computer now. It will run fine for anywhere from 5-20 minutes, then screen goes black and you can hear the fan inside the case stop at the same time. The power light on the computer stays on and you muct hold in the power button for 5 seconds to turn off the computer.

It doesn't seem to matter if I'm using the computer or not. It need only be on. Whether I have programs running or not, it will shut off.

Opened up the case, cleaned the fan/heatsink and inspected cpu (looks normal), cleaned the motherboard and all cards, took out ram and reseated it, reseated the cards. The malfunction still occurs.

Can't monitor the temps in BIOS; they do not show up there.

I have done several virus checks and spyware checks in safe mode. I have used vundofix, hijackthis, atf cleaner (I think that's the name), AVG anti spyware, spybot, AVG. Removed some crap that was causing the winantivirus2007 popups and browser redirecting. That is fixed. but now I have this problem.

Computer is not going into hibernation mode. It is set to always on, never, never, no screen saver, etc. I have double checked the display properties, and moved the mouse when it shuts down on me to confirm.

I have hooked up a different computer to this same monitor, and have been running it for a couple of hours with no problems, so at least I know it is not the monitor.

I wonder...when you hit F8 during bootup, you get the screen that allows ytou to choose to go into safe mode. On this screen, there is also an option to go into VGA mode. If I chose to do this, might it alleviate the problem? (Long shot, but I thought I'd ask).

Still lost. :-(

"Computer is not going into hibernation mode. It is set to always on, never, never, no screen saver, etc". That is under Windows. What about the settings in the BIOS for energy savings? Try S1 custom and set to never.

Resolved!!!

I removed an expansion card which was for cable tv. Well, computer has been running for some time now, without shutting off.

Conclusion: It was either an issue with the cable tv expansion card, or it was a heat issue. (The computer has been running for the last 20 minutes or so without the side panels on it.)
