Computer Wont Boot After Power Cut

v3llr · 19 Sep 2014 at 12:03

Hi there,
Yesterday my power went off at home and I later went on my PC for about 5 mins before I smelt a burning and then shortly after my PSU died with a pop.
I then went out and bought a new PSU, A Corsair CXM 500W.

The computer then booted fine and was working until I tried to turn it on this morning.
The computers fans now turn on and the GPU (which is a HD6770) fan's rpm oscillate. But nothing happens after that

I have tired removing the GPU and booting it without it, however it still wont boot.
My motherboard doesn't have a bios battery that I can take out or anything like that and I have checked all the connections from the PSU to the computer and it all seems to be connected fine. All of my sata connections are all fine as well, not that that should matter anyway as I am not even getting into the bios, or even appear to be running the POST.

If you have any ideas on what is going on and if you think the power cut destroyed my PC then please let me know.

Thanks,
Sam

Thanks, Resetting the CMOS seems to have done the trick

Just tried to boot my computer again today after turning it off last night, same thing has happened ....
I think I must have a mobo problem

Do you think this sounds like a mobo issue?

unfortunatly I cannot take the CMOS battery out of my motherboard, however I have reset the CMOS with CMOS reset jumper.
but I will still try to reset the memory and let you know how I get on.

Just Tried resetting memory.
Didint work :/ I had to unplug all of the peripherals and it has now booted, not really a solution however, as I dont want to have to do this every time I turn my PC on... I think I must have a problem with my mobo and/or graphics card. Not sure which however ...

Feel like an idiot. I could take the CMOS battery out, it was just hiding under my GPU... But yeah I think a UPS is in order, even tho the PC wasnt even on when the power cut happened ... ohh well
Thanks for all the help, it does seem to be working, for the moment at least
