Recently my computer shuts down whenever I am playing games. At first I thought it was a RAM issue, so I swapped out each stick but neither of them seemed to be broken. Then I thought overheating. I ran Core Temp and EVGA Precision to get accurate readings of what was going on in there. MY CPU was hovering around 50-55 celsius while playing, and the GPU was around 60 celsius. nothing else in the system was above 50. When it shuts down, I am unable to turn it back on immediately. Sometimes it takes 3-5 mins before it will turn on again, and it can stutter (turns on then off, then back on) when it finally does. I run a GTX 260, Asus P5KPL-CM motherboard with 4 gigs of ram, 750w power supply, CPU is Intel Core Duo E8400@3.0 ghz. Vista 64 bit os. I have the fan on the video card at 75% while gaming, and have liquid cooling for the cpu, and another additional fan on the case. No clue on what is causing the shutdown. Power supply?
The issue most likely is the chipset that isn't properly cooled. You could mount a small flexible fan to cool the chipset or use liquid cooling. More airflow would help if air goes through the components that currently lack cooling.
Hi guys its a A shutdown virus is programmed to make your computer shut itself off. It can happen from any command the specific virus chooses, be it opening a web browser or accessing your command prompt. Its harmless prank from a friend, but it can also be from someone more sinister. A reliable, updated antivirus program is always the best way to completely remove this virus, but there are ways to remove this one manually. Deleting the files and registry keys associated with the virus can help disable it.
I had a problem similar to this a while back. My southbridge was overheating, causing the shutdown. The graphics card was too close to it, causing the temperature to rise whenever i was playing games, and shutting the computer down. I recommend placing a better heatsink on the southbridge.
