Guys I 'd appreciate any assistance with this. I have this PC which recently has gone bizarre. One day it's fine the other day it drives bonkers with random reboots - like 15 or even 20 in a whole afternoon. I also ran the memory test from from Microsoft. Initially it gave a few errors. Then I opened the case cleaned it from dust, cleaned the RAM modules, and reseated them. I thought I did the trick. The next time I ran the memory test it ran fine. I also applied the extended test (X). THe next time I reboot, voila, I get two System Errors (102) then everything goes quiet again. I also ran checkdsk with the repair options. I tried running dumpchk and pstat, but to be honext I couldn't find where things were wrong and rather than continue running this and that I'd like to nip in the bud and pinpoint the problem. Unfortunately the Microsoft assistance on dumpchk isn't too helpful imho or at least what I read did not match my scenario. I am thus attaching yesterday's minidump and a pstat log, hoping that you may offer me some assistance. Thanks in advance.
