My computer shuts off completely, no blue screen ect. Also it turns right back on no trouble at all. when I play WoW and once while I was streaming a online t.v. show. I recently replaced the fan and heatsink and it seems to be running cool between 40c and 60c Ive had a friend run a program to check my computer and I think it checked all the software and he checked out the hardware finding no problems. It still shuts off. Any ideas? I would really appreciate some advice. btw sorry if any of my terminology is off I dont know much about computers!
most likely a power supply issue, or possibly Ram.
Need to know:
Power Supply brand:
Power Supply model/wattage:
Motherboard or Computer Make/Model:
Also, if it is a ram problem you cannot simply 'run a test' to check it. You have to run a memory specific test for several hours to see if memory is bad. Go download memtest 68+ and run it for at least 8 hours.
When a computer just plain turns off (no blue screen or reboot) then its usually a power issue. Most often an issue with the PSU, but a dying motherboard is also possible. I'd start by replacing the PSU (or borrowing one for a bit) to see if the problem goes away.
The 40c-60c temps, is that under load or idle? If thats idle temps you could be hitting a thermal limit in the bios. 60c idle is much too hot.
