Computer restarts only during games

by F0urL34f - 7/28/13 3:58 AM

Hi there, Im wondering if anyone can help me with a tricky situation Im in. The current problem Im having is that my Desktop is going cold during gaming, it happens during high end ultra mode gaming and basic graphic games as well, when it powers off it immediately powers back on, no BSOD, no error, just windows recovery and asking me if I wanna boot in safe mode. Ive already turned off auto reboot and I still recieved no error message or anything. This has not (knock on wood) happened while doing anything on this computer except running game oriented programs, I can video edit, produce movies and watch netflix and stream all day and it wont restart.
I have cleaned, dusted, applied new thermal paste, bought a new after market heatsink, dropped my cpu heat to never over 65 even under high load. My case is kept clean, I have all wires as neat as they will fit, good air circulation and plenty of room around all sides.
This is where I started running out of ideas for problems, I ran speedfan and other tools to cross check temps and volts, temps never reach over 65 for anything including core and GPU, the interesting reading was that my +12V rail on speed fan reads constant fluctuation but steady between +10.38V - +10.47V From what Im reading on other forums is thats extremely low and that its probably my powersupply, so I checked voltages while in Bios and as far as I could tell they were all fine but on desktop with OS running multiple programs are feeding me undervoltaged readings. Computer specs as follows please any help would be amazing, I just dont want to get a new PSU unless I have concensus from most people about what this is, THANK YOU ALL
