Inexplicable restarts

Thanks for your patient help and analysis, zbook. I'll step through some of your suggestions over the next few days - there's a lot to do and some look a bit hairy! That is, for a PC that is working sweetly right now...

Meanwhile, as requested in the BSOD thread (sorry, I misunderstood and posted there by mistake), I've attached both ZIP files.

One step I did try right away was to answer your question about whether my BIOS is up-to-date. I had no success at the AMI site but did get some info from this commercial site:

PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??
