I popped on 7 after building the machine to check if there were any hardware issues. I have some weird issues:

1. The computer will seem to crash if left idle for more than say ~20 minutes.
2. The computer does not crash when under intensive use, such as playing Far Cry 2 at maximum settings in Direct X 9.
3. Ran Memtest 86 and Prime95 overnight, both were fine.
4. Tried 3dmark vantage, fine.
5. During DVD playback it often BSOD's with some error message about video

The computer also will randomly "crash" if slightly disturbed (I bumped it once). The weird part is that it does not BSOD or freeze fully, but usually go into a state of extreme slowness (cursor can barely even be moved). Once in a blue moon it will BSOD with video driver errors. I tried reinstalling drivers and whatnot, but it did not seem to help. I have a small case but plenty of fans, and a huge cpu cooler. I am thinking that it must be the Videocard, or perhaps the PSU. Memory would normally be in question but it seems to have passed memtest so.....

Specs:
i7 860 1156
intel p55 based mobo
Radeon 4870 Video
8 gigs corsair memory
Thermaltake 850 PSU (single +12v, 62a, it looked good at the time)
LG Blu Ray ( I think LG? )
1 500 gig Sata ( I believe WD or Seagate)

Help?! I posted this elsewhere but Ive always found the best help here on this forum....hoping you guys can give me a hand :-)
 
Gigabyte UD2 mATX

edit:

Also forget to mention that Im looking to undervolt / underclock everything in the system slightly for purpose of longevity and power consumption, does this have much of an affect on i7's or my video card?
 
Well, sorry, but it is this forum's policy to provide support and advice for MSI Retail Products only.  This is no general hardware forum and we make no exceptions to this rule.  All other topics regarding non-MSI systems in the past were closed and I am going to lock this one as well.  Try to find help in an Gigabyte forum or general hardware forum.
