Possible videocard crashes

[Allbrancooke]

Complete computer crash, as if power plug has been pulled. Possible video card (Nvidia GTX 560) problem that is making it impossible to do anything. Crashes when playing games or doing too many things at once. Crashes while starting up, shutting down, running a program, and in safe mode. I've tried updating, uninstalling, and reinstalling drivers for the video card. I have done C Cleaner, Housecall, and restoring. I've used all my knowledge and power to fix this problem, but it's beyond me. Would love your guys' input; any questions or details on anything, feel free to ask.

EDIT: Firewall is not working, though i have swept around looking for any threats. Also, logs are saying it is the video card that has stopped working and recovering. Most errors occur during sleep mode.

If you just recently upgraded your video card it could be that your current power supply is undersized. Could you post your specs? My guess is the PSU is undersized for your system.

It's not recent; I've had the card for a year now. I cannot post the specs now, as I am at work. I will post them once I get home. What i can tell you now is it's a 750W PSU.

Interesting. Wonder if it could be a connection issue. Have you tried reseating all the power connections and also cards, etc?

No, I've taken a look around inside, everything seemed okay. I'll give it a try.

I'm looking back on notes i have taken and i forgot to mention the firewall is not working. Again though, i swept all over the place looking for something like that. Another thing is the logs have said again and again that the video card has stopped working and has recovered. When it goes into sleep mode is when most errors occur. I'll be adding all this to my question.

For anyone experiencing a similar problem, it was a driver problem. After much troubleshooting I contacted someone about this, and with their help, was able to fix the card.
