Help! My english is not great so please try to understand. When i press the power button some fans work like the processor and front. Monitor, mouse and keyboard are not turning on, no light from them. Disk drive works because it makes a noise. It also take many press of the on button to power the PC..
I have tried reseating the gpu and ram too.

Is this a psu or mobo problem?
