BSOD and restarts randomly, 0x0000007f and 0x0000001e

Thanks for the replies, I've tried several restarts, driver verifier still only shows microsoft drivers...

The system seems to crash randomly. It could stay up for 12-14 hours or so with no problem, or crash in 30 minutes... this makes it pretty difficult to troubleshoot as it takes a while to see if what I've tried worked. (I was sure it was the power supply at first, as it ran for a while after I swapped it, but then still eventually crashed)

My only other thoughts are it possibly being the video card or motherboard. The motherboard passes the visual inspection (no bulging or blown caps) same with the video card, but I guess its still possible one of these is the problem, but that still wouldn't explain this strange driver problem with driver verifier.

Did I mention how much I love Dell computers? :-/

Thanks for the reply! I've actually just started doing just that! the install just finished, i'm working on migrating the data back. I'm worried that this won't resolve the problem.... which would still leave me guessing as to the cause. if this doesn't resolve it I guess my only 2 items to point to are motherboard (difficult to diagnose, unless you see some blown caps, which I don't) or possible the video card (although its passed every stress test I've thrown at it trying to get ti to crash)

One strange thing I noticed.... is that Hyperthreading was enabled in BIOS (it came like this from dell, but it shipped with an i5 which doesn't support hyper threading). Just to be safe I disabled Hyperthreading. not sure if this could have been causing it or not, I only noticed it after I wiped the computer.
