restart

My Windows 7 almost always restarts when I keep it idle for ~20-30mins. It happened randomly before, but lately, if I leave the computer I can be sure it's gonna restart after those 30mins. It never happens when I play games or work tho, just when it's idle.

It's a fresh install of Windows 7 64bit. I had also problems while installing it, it always crashed while finalizing the install and I had to reinstall again. Eventually it installed on 3rd or 4th try after I deleted all of my partitions and added them again.

I thought it might have been a hardware problem, but temperatures seem to be okay and I have no idea how to track what might have been causing it.

Any ideas?

I'm running Windows 7 64bit on:

Gigabyte EX58-UD4P
Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz
NVIDIA GeForce GTX 260
6GB of DDR3 1066Mhz RAM
WDC WD1001FALS-00J7B0 1TB SATA II

I have a very bad feeling it might be something with HDD and its compatibility with Windows 7 as I haven't had those problems for 1 year while I had Vista.

Windows 7 on a 64-bit computer

as seen on Super User - Search for 'Super User'
I read on Wikipedia that Windows 7 on a 64-bit PC needs twice as much RAM as on a 32-bit PC. I understand why is that: every number stored in memory takes 8 bytes rather than just 4. That, in simple terms, means that your amount of RAM is reduced to half when you use Windows 7 on a 64-bit computer… >>> More
