So basically I will be In the middle of something and my pc just dies, not so much shuts down more like a power failure, it then restarts itself. It hasnt done it during any gaming so im sure its not anything overheating, monitoring programs says all mobo/processor/graphics card are all in good ranges as well as all voltages. Ive recently added a Hauppauge HVR-2250, an EVGA Geforce 465 GTX, and a ZALMAN CNPS 9700 NT, as well as Installed Win 7 x64, and before these upgrades I had no problems like this. The rest of my Hardware is listed on my profile. The only thing I can think it is is my psu (Corsiar CMPSU-400CX) is going out or maybe i knocked something loose with my hardware upgrades. Also my cpu fan is touching the bottom of my power supply fan guard but is not pressing too hard against it whereas my last one didn't if that changes anything. Event viewer just shows Kernal-Power in the logs listed as critical (event ID: 41). anyways just wanted to hear any other thoughts before i go and replace my power supply, thanks ahead of time.
