|I recently started having problems turning on my PC after having its extension cord unplugged. I would try to turn it on without any reaction, come back after a few minutes and try again and with some random delay of a few seconds it would turn on, often while not actually pressing the button.|
When I did not unplug the PC, it seemed to be fine - until today:
My PC does not turn on anymore at all. No fans, no beep, nothing. However, the little green LED on the mainboard is on when the PC is plugged in.
I have unplugged all unnecessary components and manually bridged the power on pins (to make sure its not the power switch), no change.
What should I replace? The fact that it started happening whenever my PC was completely disconnected from the power supply made me thing it could be the CMOS battery, but replacing it didn't change anything.
The computer is about 4 years old, so I would next replace the PSU, or could it be the motherboard? Are there any other components that could cause such an issue?
Thank you for your help!
I built the computer myself 4 years ago, the components are:
Mainboard: Asus P5W DH Deluxe
PSU: Be quiet! BQT-ES-550W
RAM: 4x1GB GEIL
CPU: Intel Core 2 Duo E6600 2.4Ghz
Graphics Card: Gainward GTS 250
Sound Card: Creative X-Fi Extreme Music (took it out as it recently stopped working - unrecognized device...)
