I have a very interesting problem. After exhaustive troubleshooting with a random reboot issue, I have discovered the culprit. (I can reliably recreate reboot with OCCT torture test). Here is my issue: When my cable is connected from my cable modem to my computer (motherboard with onboard lan) the reboot will occur. When I test for a reboot with the network cable unplugged, no reboot...machine is rock solid (ran stability/torture test for over 8 hours). I tried this test same test at my buddy's apartment. My machine would NOT reboot with or without the internet connection. The only difference in setup is that he is using a router and I am not. Has anybody run into this sort of flakiness before? Would a router solve my problem or am I dealing with something more complicated (perhaps a wiring issue)? I would appreciate any help. Thanks!
