System crashes and restarts when playing games no bsod displayed
Hi this problem has nearly ruined me and cost a fortune so far, first I'll explain the problem about 6 months ago I had a PSU blow out on me, so I replaced it and all was well for a time when the PC would shut down and then restart without even showing a BSOD, at first it was now and then but gradually got worse. At first I thought it might of been the CPU overheating, I also thought that when the PSU blew it caused damage to the MB. So over a period of time I have ended up replacing all the hardware. For a time it seemed okay but the problem soon returned. (just to note it only shuts down when playing or starting games, I can surf the net or play videos etc without a problem).
My next thought was that it was a software conflict so I have ended up rebuilding a second PC, with a new HDD just incase it was a virus etc, I've loaded Windows 7 (home) 32bit, installed the graphics card (GeForce 560 Ti) with latest Nvidia drivers and a Asus sound card. I then installed Minecraft just as a test game and sure enough it crashes.
So I have eliminated the possibility of it being a hardware problem or a software conflict. I then thought it may of been the graphic card drivers so I uninstalled the latest driver and installed a older driver, but the problem remaines.
Whilst trying to check detals of my system, I noticed that the "Windows Experiance Index" score was only 1.0 whereas in the past it's always around 5.something, it shows gaming as 1.0 and Gaming Graphics as 1.0, so being a new install I cliked on the "Refresh Now" button the test starts but when it gets to "Direct 3D 9 Texture Load Assessment" the system crashes as if I was playing a game. I then realise that I can not use the Windows Aero desktop as the experiance score is so low needs to be 3.0 or higher.
When I have looked at the Events Log I notice when the system crashes it reports "41 Kernal power" etc I've looked at the Microsoft website but dissmissed their explanations as the powersupply I have is new and powerfull enough.
I have searched the internet for days now without getting any answers I have tried upping the power for the CPU and ram but made no difference. So Windows 7 forums is my last chance to get this sorted. I have come to the thought that theres something within Windows 7 that detects when huge amounts of graphics are being shifted and cant cope so it shuts down. As I stated this is on two different Asus MB's and Intel i5's.
It has me stumped, please help before I smash the lot up.
