Constant beep from APC, now computer won't power up

post #1 of 17
Thread Starter 
So I was playing Age of Conan when suddenly my computer just turned off and my APC was making a constant beep. I turned off my APC for a few mins and turned it back on, it is working again, but now the power button on my computer does nothing. I've tried plugging it into my APC and into my power strip neither of which are working.

In case it matters,

No, but the outlet that my surge protector is plugged into is working.

Can you unhook your PSU from the system, jump it and see if it is working by plugging in a fan? Or better still verify its output with a voltage-meter?

I've got a voltage meter. Where should I test? And should I test AC or DC? Also, I doubt it really matters, but I just looked, It's DirectUPS brand not APC

Try "resetting" your PSU. I find that if I do something stupid to my rig and I short out my PSU, unplugging the black AC cord and the 24-pin ATX plug that goes to the motherboard for about a minute will reset your PSU. Plug it back in and you'll be good.

Aigt, I tried the guide, and I got 0, although I think the leads on my multimeter might be too big because I took a power supply I have laying around, plugged it into the wall, also got 0.

Someone mentioned to 'reset' your psu. Its a good suggestion, and sometimes its the basic things that do that. I have a machine here that needs a PSU reset every time there is a power failure. Its worth a shot and only takes a minute.

Resetting it does nothing. Mine requires a reset, as well, after power shortages, but it usually only needs me to turn the I/O switch to O for 5 seconds.

It's worth noting that for a time, I had a massive number of power shortages happening, never figured out what caused them, but I would just get power shortages when I would move my chair a certain way, or nudge my computer (even if I wasn't touching the power cable at all) to the extent that some days I would get 3-4 of them per day. They stopped a few weeks ago, but it might have something to do with it.
