PC Turns off while playing games

November 10, 2012 at 01:09:48
Specs: Windows 7, 3.3 GHz 3.5GB Ram
I have recently finished my gaming PC that I built from scratch, and annoyingly, over the past few months the PC has developed a habit of turning off, without warning, or any Windows shut down procedure. It just simply looses power. I have recently upgraded from a 580W PSU to a 750W PSU and the problem persists. I had looked through the windows logs, and noticed a error with AVG Free 13. So, thinking this must be it, I uninstalled AVG and went with a different anti-virus. Well, ladies and gentlemen, our problem is back. I have nowhere to really turn now. I just can't fix this problem. Does anyone have any ideas?

Have you checked the temperatures at load? It could be turning itself off because of thermal overload.

U didn't bother list the system specs.
Use BIOS or AIDA64 to check system temperature especially CPU temp.

I noticed 3.5GB Ram, do u have 32 bit of win7 installed?

Either your CPU is overheating or your PSU is overloaded.

"I have recently upgraded from a 580W PSU to a 750W PSU and the problem persists"

Without knowing the make/model or specs of either PSU, it's impossible to say if you upgraded or downgraded. And it would be helpful if you'd list your complete system specs, we have no idea what type of hardware you're working with.

I recommend HWMonitor for checking your temperature from within Windows.
Absolutely list your exact detailed system specs (as indicated above) including all of the power supply's specs (both of them).
Since you "...just finished...gaming PC....from scratch..." please look up your CPU/heat sink installation here:
and make sure that you installed it correctly (not too much or too little thermal compound). Intel's preapplied thermal compound and similar being an exception of course, then follow those instructions.
Post back specs, temperature readings, and anything else that you have tried or noticed.

You have to be a little bit crazy to keep you from going insane.
