Optiplex 760 DT keeps rebooting every one hour or so
While i'm in the middle of a Windows 7 session, my optiplex 760 reboots every hour or so without telling me it will. So it like powers off and then 3 seconds later it reboots. It's running a q8400 quad core, 4gb of ram, and 160gb harddisk. Can anyone help me?

Considering the age of this model (the manual is dated 2008) it could be heat related, poor CPU heatsink thermal paste, power supply, CPU, motherboard, etc.
First thing I would do is clean out the dust from inside the case, including the heatsink and then replace the CPU heatsink compound. That is an under $10 item for good quality (Arctic Silver) thermal compound. Clean off the old and apply new. See if that helps.
