Ok when i hit the power switch on the back of the power suply, the computer turns on wihout even hitting the switch in front.

It turns ons and all the hard drive runs, all the fans work, but nothing comes on on the screen. I have Intel D915GAG mobo with P4 3.0 Lga775 CPU

before all this happened, the comp was working all perfect, but i got a new case, and i put all the hardware on the new case, and i forgot to put the mobo spacers that go between the case and the mobo

maybe soemthing happened to mobo? i want to be exactly sure whats the problem before i go buy a new part. Any help is appriciated

It also has an integrated video card built into it, but even when i put in an addition video card, still nothing comes on
 
I rechecked all the wires, everything is connected as its suppose to, but still cant figure out
 
If you forgot to put in the standoffs, and fired the machine with the mobo flush up against the chassis, chances are you may have blown your motherboard.

Is your speaker hooked up to hear bios beeps?

If you aren't hearing anything with the speaker hooked chances are its your mobo. I worked on a machine exactly like this earlier in the week, tested it down to the mobo then noticed all the scortching when I removed it.

You will need to troubleshoot to be 100% sure.

Remove all cards, ide/sata devices.

Take it down to CPU/RAM/PSU/VID

Then if possible switch PSU and try, switch VID and try, switch RAM and try.

If you make it that far, then its either CPU or RAM.

One trick I like to use if you have a working speaker is to remove the RAM and fire it. If it doesn't scream at you, chances are you know its mobo.

Overclockers.com had a recent front-page challenge to solve this problem. Their twist was that it even happened with the motherboard out of the case.

Their solution is here.

I understand that, but we should properly rule it out.

I do not want to give anyone advice, send them for a new mobo, if it isn't needed.

Always be sure, right? ;)
