my power supply is new to me (master power 520 watt) i've been having a problem with random restarts or crashes during a specific game which i've never had before (WOW) in hopes that its not my memory which is pretty new, i've been working on the heating issue. i took the side of my computer off and aimed a small fan in it which seemed to take away the problem. so i went out and bought a GPU fan which worked for awhile then the problem came back up. so i bought a new case fan which hasn't worked. when installing the case fan i realised that my powersupply has two fans, neither of which spin when the computer is on. i've looked everywhere on my comp for a control to get these things going. i was wondering if indeed this issue is able to resolved in the BIOS or in Windows itself, or if my power supply is faulty? any info would be greatly appreciated.
