I have an XP sp3 machine that will start randomly rebooting on its own every 2 weeks to the day. I do a rollback and it works fine again for 2 weeks...
What I have already tried:
I did memtest, flashed the mb bios, chkdsk on the hd, updated all device drivers, changed AV programs from symantec to microsoft security essentials, used spybot and several AV to check the machine for virus/spyware, All microsoft updates and current on the computer, and the machine does not give me a BSOD when it does this. This is just a desktop and not a server and it gets rebooted often so probably not a memory leak issue. TOTALLY baffled by this.
What is so incredibly strange is that his happens exactly 2 weeks after I rollback the machine to an earlier date, (doesn't matter when I roll it back to prior to the problem.)
Any suggestions would be appreciated.
