I have my pc powered by a surge protector which is connected to an outlet that was switched off by the lightswitch on accident.

Now my PC will not boot when going to sleep and when shutting down.

I have to unplug and use the case power button the back to actually get my PC to turn on again, but this seems to work at random.

The PC will try to boot then shut off.

It doesn't seem to be a PSU issue since when it does boot it works perfectly fine.

My Hunch is that its the Motherboard since I was getting a blank screen with the dual bios before it shutoff. I tried to remedy this and flashed my bios with an update but that didn't fix the issue.

How can I remedy this and or figure out what is going on?

Who said the GPU was at fault? I'm questioning your PSU, and the easiest way to test it is to modify startup load. If you want a similar test, put the computer to sleep and see if it wakes up properly or if it crashes.

Try using a different circuit and NEVER, NEVER, NEVER connect a computer to a switched outlet!

If the PC has trouble starting, try removing the GPU and using only integrated graphics, and if that fails then you'll need to start replacing things starting with your PSU.

I will try that, but I am actually able to play games without issues when I get the computer booted so the GPU I fon't think it at fault.

One of my friends recommended removing the cmos(motherboard battery thing) and leaving it out for 5 minutes or longer and then see if that works.

This is definitely a voltage issue because I was having ZERO issues with this until I flipped that switch lol.

Oh sorry for the confusion on my end for that.

Right now if I put it to sleep It absolutely will not boot until I do the unplugged and replug fix a couple of times.

Based on what you have said I went ahead and bought another psu. I will give it a try and see oif it fixes the problem when it arrives.

The friend's idea of removing the mobo battery is only about ¼ of the process of clearing the BIOS to factory defaults. I recommend NOT doing that until you know the entire process.

However, you are about to replace your PSU, which I agree is a good probable cause of your problem. IF that does not solve your trouble, post back here for a complete outline of how to reset the BIOS completely.

If sleep doesn't work then it's almost 100% PSU or mobo. Hopefully the PSU replacement solves it, but if it doesn't then you'll have issues (mobo is annoying to replace)

So after getting the PSU it seems my windows and Hard Drives got a little messed up. That doesn't matter for this case though. It was the PSU that was the cause and now its resolved.

@Paperdoc, I didn't mean to downvote your answer and it won't let me fix that so sorry :/

Thanks for the help everyone!

Probably corruption from crashing so much. Hopefully you can still recover data from them.



I've seen this problem too many times to count ;)
