Been having some issues with rebooting my desktop PC after it has been running for 3-4 days in row.
Would shut the machine done in the evening and start up the next morning to be greeted with continual rebooting and fans (GPU I think) spinning 100%. The behaviour is after I press power button:
fans spin hard - "blurred" beep sounds, bit of disk activity - no power and stop/silence - repeat.
To break this cycle, I have had to leave the PC switch off at the back fro 2-3 days upon which it will start up.
Specs are (bought 2008): GA-P35-DS3P with Intel Q6660 CPU, Geforce 8800GTS, 8Gb RAM, Oem 430W PSU from case Mfg, WD 500Gb and 2Tb Green disks, Win7 Ultimate.
Have played with reseating RAM, etc with little success. I have read that 400W was a minimum for PSU size with this GPU, adding extra disk - could this be it, more power? Or is it a heat issue as case is not well vented.
Any ideas team on what could be the issue as it it driving up the wall?
