Restart while playing games

[jimjai]

Hi, there.
I have an Asus P4R800-VM motherboard. The system restarts while playing games. It doesn't restart immediately; it restarts after 10-20 minutes of playing. I do not have a video card, its onboard video. I am assuming there's something wrong with the onboard chipset video. Sometimes it gives me an error "Device failure" and then my screen's color goes to like 24color and stuff. I have also updated the BIOS to the lastest but didn't help. The temp is normal, no overheating for sure. Need help, thanks

WHat are your CPU temps right after it restarts? How about voltages?

 

[jimjai]

My cpu temp is between 30-50, normal temp. I did not overclock so the voltage is defualt.

I did not overclock so the voltage is defualt.

During operation there's no such thing as "default" voltage as its constantly in flux. Have a look, it's a quick and easy thing to check ... usually its the 5V rail that fails people

 

[jimjai]

Ya it's around 5 for voltage

you need to get a new video card, onboard aren't to reliable

- The other voltages?
- Could the onboard be overheated?

could be overheating or maybe bad ram or something. i would check temps first and then run ram through a few tests. do you bluescreen or does it just reboot? if it just reboots probably overheating, if bluescreen possibly RAM failure. like 90% of bluescreens are caused by bad RAM.

Yeah i suspect it might possibly be overheating but that would be a hell of a case ... i.e., if the onboard video is overheating the CPU is definitely overheating especially considering (a) onboard setups are typically non-overheaters and (b) its a Radeon9200 based setup which dont make much heat even when pushed
