I have a custom built computer that has run smoothly for the last year or so.
Today, my wife put the computer on standby and when she went to turn it back on later - nothing happened. When I came home I pushed the power switch on the case and there was nothing (as though it was unplugged).
Now, I'm a veteran PC builder and user. I'm not a HUGE expert, but I've solved most of my problems. So, I went through all the troubleshooting steps. I tried resetting the surge protector. Unplugging and re-plugging everything (including the power supply cable that goes to the motherboard). I cleared the CMOS and still nothing.
Then, I went ahead and tested the power supply with a power supply tester. All the lights went up and the fans connected to the power supply (and the power supply fan) turned on. Then, as soon as I plugged the cable back into the motherboard - back to nothing again when I pushed the power button on the case.
I thought that it might have been the motherboard, but there's a little green light (which has always been there) that stays on the motherboard when the computer is plugged in (showing that power is going to the motherboard). I had no other symptoms on this computer leading up to this EXCEPT for the fact that that power switch has proven flaky in the past. Once when I moved into a new apartment, I had to push the power button several times before it came back on.
So I guess what I'm needing is to ask you all: IS IT SAFE TO ASSUME THIS IS A BAD POWER BUTTON ON THE CASE? Or is there something else that could be a likely culprit????
I really appreciate your time.
