OK, I've got a strange issue here, and unfortunately it seems to be semi-random right now so it's proving hard to debug. I have a system connected to a UPS. It's been on there for ~10 months but the problems only started happening recently.
My computer will suddenly lose power. Then the power button won't work to turn it back on. I have to unplug the system from the UPS, rock the switch on the power supply (usually wait a few seconds), then plug it back in, turn it on and everything works. If I just rock the switch, but don't unplug from UPS, it won't work. If I unplug it but don't rock the switch then an orange MOBO light comes on, but the system won't power up until I rock the switch. So I feel like whatever is causing the problem is tripping some sort of safety mechanism on the power supply.
The system might lose power right after it loads Windows or it might go for hours and hours before losing power.
Some details that may or may not be related to this issue:
-when I plug the computer back into the UPS, I see sparks - like static electricity going from the prongs on the plug to the holes in the outlet in the UPS
-When I first built this computer (ten months ago), after a few days the power supply I originally used just up and died. I sent it in for warranty work and put in a new, different brand power supply. Haven't had issues from then until now
-once, a year ago, I thought my 5.1 computer speakers, also plugged into this UPS, were broken. One day it just stopped turning on. I tried changing out the fuse on the speakers and nothing I tried worked. I unplugged it from the UPS and plugged it into a different outlet on the UPS and it started working again.
It LOOKS like it might be a faulty UPS - although I'm confused as to why these problems are only happening intermittently. The UPS is not making any beeping noises as though it's lost mains power. However, I guess it's also possible the power supply is at fault. So, although my first instinct is to replace the UPS, I'd like to see what the tom's hardware crowd thinks first.
