A couple weeks ago I put my computer in standby. Came back an hour later to find it dead.
The fans in the psu spin, all case fans spin, cpu fans spin, motherboard light is on. No signal to the monitor.
After a week of troubleshooting I decided to get a new motherboard. It just arrived today.
I hooked it all up: CPU, Memory, hard drives, floppy drive, cd drives and video card.
Turned it on and nothing happened just like before. I removed the cd and floppy drives and tried that.. nothing. Tinkered around with it for a while.. gave up on it twice.
Then... I put a different video card in.. turned it on and it booted into windows without a problem! So just out of curiosity I put the orignal video card back in it. It booted fine then as well. So I hooked the rest of the components up, set it up on my desk, put the side panels back on and plugged it all in. Turned it on and NOTHING.
I removed all uneccesary components again leaving it with just cpu, memory and video card. Nothing worked.
I pulled the motherboard out of the case and assembled it outside of the case. (maybe it was being grounded on the case?) Still doesn't work.
The system doesn't POST at all. No signal to the monitor. My case doesn't have an internal speaker so I can't hear beep codes. (I had it in a different case before that had an internal speaker and I didn't get any beeps then either.. so I'm assuming im not now)
So why did it work those 2 times then quit??? It's a brand new motherboard. The psu doesn't show any signs of having problems.
I don't know what to do. Please help me.
