After I had shut down my computer and unplugged it to clean my desk I hooked everything back up to find that it would not turn on. The PSU, fans, or lights do nothing when I hit the power button. The green power light on the motherboard is on and devices with lights turn on with the computer off as well.
I know it is not the PSU because when plugged into my brothers computer it will start.
Have tried: Resting CMOS Changing plugs checking all cords, and re checking all cords WAS not even bumped when I moved it Removing GFX cards No damage can be seen on motherboard
Additonal INFO: This happened a few days ago but I waited an 10 min and it turned on again I built the whole computer from scratch. AMD Phenom, 750W, 4GB RAM, 2 250GTS GFX
So, without any spare parts how do I tell if my CPU has failed or my motherboard?
