Windows 7 randomly rebooting

Specs: Windows 7 Home Premium OEM 64-bit
Hi, I recently upgraded my computer hardware, and replaced winXp with Win7 home premium oem 64-bit. Since this upgrade, my WIndows reboots at random intervals. Sometimes the screen shows random pixels before the reboot but not always. Sometimes it shows the blue screen of death (saying "atempt was made to write on a read-only memory").

Windows' own memorytest says everything is fine. I had memtest86+ run for 8 hours straight: no problem, no reboot. So I think this is not a hardware issue, since the computer keeps running for long periods of time if Windows is not started.

Windows has been reinstalled already, all drivers have been updated, Windows has been updated. The problem still remains.

I've run out of ideas. Does anyone have any suggestions?

Here's the complete hardware profile:

Processor: INTEL Core i3-530 2.93Ghz
Memory: CORSAIR TwinX DDR3 1333Mhz DHX CL9 KIT
Videocard: integrated
DirectX-version: DirectX 10
Motherboard: ASUS P7H55D-M EVO
Harddrive: SAMSUNG 1000GB F3 7200rpm 32Mb SATA2 HD103SJ
Power: corsair 450W

Thanks for any help you can give.

if ir runs constantly when your not doing anything, but shuts down while your working, it would suggest memory and also over heating.
Memory, check each stick indivually,take out each stick one at a time, try each stick in a different slot, although memtest was ok, it may still be an issue,
Overheating maybe too much dust on the cpu block,try giving it a clean, if you feel up to it, take off the cooling block, clean away the thermal grease replace grease and block.
finally did run window win7 compatability test before installing ?

i hate computers!
but cant help myself....

microsoft has free support for subscribers, why not ask them
