Ok last night I mistakently tripped over the surge protector that my computer was plugged into. I didn't pay it much mind went straight to bed.

 

However today now, I'm trying to turn it on but no luck. I can hear noise indicating that the fans and hard drive are spinning but nothing comes up on screen. Also, there was this blue LED light that shines when it's on but I'm not seeing that anymore. I can't even turn it off my holding down on the power button; I have to actually unplug the pwoer cord.

 

Any ideas on what might be the problem? Help please.

I don't really know, but do you think it's possible you fried your mobo?

These kinds of things are usually a blown power supply or bad ram.

That was my first thought, but if power is still going to the fans and hdd...

Well it could still be a damaged PSU seeing as how the LED lights are not coming on.

You may have 12v going to the hdd and fans, but you might not have 3.3v and 5v going where they should. Try with another ps. You will be glad you did.

can you get to the bios? are you using an SSD?

The power cut could have caused a voltage spike which in turn could have damaged either your PSU or motherboard.

See if you can get hold of a power supply tester, that may help determine whether your power supply is defect or not. Also, have you tried resetting the BIOS, by removing and reseating the CMOS battery?

Yea I've tried reseating, didn't work. I think the PSU's the problem, and I'm going to have a technician take a look at it.

If you want to save some money, you can get a multimeter from your local hardware or car parts store for about $10 and check the PSU voltages yourself. Just set the dial to DCV, or DC Voltage... image_12568.jpg

Thanks, I'll check it out.
