Hi, guys... hopefully some of you can help me with my PC which is refusing to start. Here's the problem:
For at least six months, I have noticed a barely audible, very high-frequency whine coming from the PC when it is plugged in. Not just when it is on, but the moment the switch at the back of the case (the PSU switch) is turned on. I unplugged the 20+4 ATX connector and 4-pin power connector from the MB and the whine still occurs, so it must be coming from the PSU.
I was away from home for the past four days so I had turned the PC off and unplugged it from the wall outlet in my absence. Upon returning from my trip yesterday, I plugged the AC cord in to the wall and pressed the power switch on the front of the PC case. Nothing happened except I heard the before-mentioned whine. I opened up the case and everything looks normal. The little orange LED near the CMOS battery is illuminated, like it always is when power is supplied to the PSU and the computer has not yet been switched on.
First thing I did was troubleshoot the power switch that leads from the front of the Antec case to the MB by disconnect it from the MB and jumping the + and - terminals directly. This did nothing. Still the same whine; still the LED remains lit.
I then disconnected all the fans (4), DVD drives (2), and secondary HDD from the PSU. Still nothing when I attempted to start up.
BTW, I have been running this build for at least 18 months without problems.
What should I do next?
