Computer won't power on.

post #1 of 9
Thread Starter 
My friend's computer won't power on. Everything is plugged properly. It was working before now it won't power on at all.

The 'green' light on the motherboard still lights up, but when pushing the power button it doesn't turn on the computer what so ever. The cpu fan doesn't spin, no beeping sounds, case fans, hard drive...no sound at all.

Is the power supply dead? If so why does the 'green' light still light on.

Thanks!

* don't know if this is the right section to post this, but it might be a power supply issue, so I guess it here?

that would more then likely be your psu mine just did the same thing the other day take it out and test it if you can with a paperclip

edit if you dont know the paperclip test find the green wire in the 24pin put one end in the green and the other in the black one next to it and then turn it on to see if it powers up

Try wiggling the 24pin connector as you hit the power button, the green light can still appear but the computer wont turn on because all the connections are not connected.

Any specifics on the motherboard? I had a similar problem on my first build.. I plugged in the 24 Pin connector and failed to notice a 4 Pin connector on the other side of the mobo.. Many hours we're spent trying to figure out why it wouldnt boot... and Connecting that 4pin happened to be the 2nd instruction or item in the manual to do XD

Clear the cmos and try booting with only one stick of memory if that doesn't work try a different stick. If it has on board video than take out the video card and use the on board vga.
You can also unplug the hd's just to see if it will post to the bios.
Unplug everything not needed.
GL hope this helps.
