Sounds like it could be several possible problems.First, when it reboots, is it turning off then powering back on?  If so, probably an issue with the power supply.  (My PSU is dying on my newer comp too.  /cry)Other than that, might need some more diagnostics.  Could be a corruption in windows, could be a physical problem on the mobo, could be something else with the power supply, could be something coming unplugged (I swear, I once had the heatsink come loose on my processor, randomly overheated and shut down the comp, lol).
