PC freezes while playing games

MB: Gigabyte ep43-ds3l
CPU: Intel E8500
VC: HD4870
MEM: 4GB GSKILL
SCREEN:22"
PSU: seasonic W750
Windows 7 64bit

while playing games (like COD,STARCRAFT2 etc.) the game and the sound freezes. The only way to stop it is by pressing the reset botton. Sometimes after reset windows doesnt start so I turn off the pc turn the psu switch off and on again then it stars normally.

Could be a PSU issue if you have to do all that, though I've generally heard better things about Seasonic units. Also, when is the last time you took a can of compressed air and cleaned out the case? If you haven't done that in a while, could be a build up of dust and such preventing fans from properly functioning, and there for the extra time taken in turning off the PC and then doing the PSU switch might be just enough to let it cool down.

I did a complete cleaning a few days ago

Well before dumping money into a new PSU, can grab a copy of Memtest and check the memory, then do a chkdsk on your main HDD off a windows install dvd. Make sure the RAM and HDD are good. Then possibly using furmark or another program to put highload on the GFX card with out testing the CPU, we can see if that has errors. If all those pass, I think the PSU would be at fault.

Can you make picture with camera when it freezes next time? Does the screen cover in green, white or whatever colour?

memtest and chkdsk didnt found problems. furmark got the temp to 88 but i dint get any kind of errors.

when the game freezes there isnt any color cover it.

i should mention my psu droped dead a few days ago and a the store changed it.
maybe something wrong with the psu? or maybe some connections are not well?

Almost 2 days past no answer....
I want to add that now even while on windows doing nothing the PC restarts itself without warning.

A great way to figure out of you have a hardware or software probably is to just boot up into a Linux Live CD (such as Ubuntu). If it works flawlessly for a while, then you have an issue with the installed OS. If it still freezes up, you're looking at a hardware issue.

Got it back from the store.. It was a hard drive problem - 8 bad sectors
