I'm having a strange issue. I finished building my gaming PC yesterday and had a start up problem. With the power button, fans would work for 1-2 secs and then shut down. After turning off/on and unplugging the psu a couple of times and insisting, I finally got the system to boot up. Installed windows, drivers and everyone worked great. Installed game to try out GPU and no problems. I turned the computer off before going to bed, tried turning it back on in the morning and had the same issue. Had to get to work so I had no time to try unplugging the PSU. The only difference was that, at times, pressing the power button on the case did nothing. Other times, the fans would work for 1-2 secs again, and then shut down. I don't think it's the PSU because once I got the PC to boot, it worked perfectly. Any thoughts on what I could try?
CPU: Intel i7-2600k
GPU: EVGA Nvidia 660ti
MoBo: Asus P8Z77-M PRO
PSU: Thermaltake 500w
Sounds like some kind of short or another wiring issue, but, can you post what specs and I'm talking total specs all the way down to what stand-offs you used and if or if not you used thermal gels etc.
Regarding specs, I'm a beginner (noob) so I guess it's all standard. I didnt overclock anything or configure anything. I did not use any thermal gel. Basically used only what came with the PC components and Cooler Master case. If there is anything else I can add, I'd appreciate it if you let me know. Thanks again!
