Another "what on earth is wrong with my system" thread

I've had a busy weekend trying to upgrade 2 systems and it's all gone rather wrong.

I wanted to swap 2 cpu's over, swap a graphics card around and install some more RAM, but i've run into a problem in that my desktop PC isn't posting.

The only thing that's changed in the machine is the CPU, RAM, cooler and graphics card. I've also moved it to a new case. I've tried using the old CPU, the old RAM, the old graphics card and nothing is making it do anything. To make matters worse the case doesn't have a speaker, I did try connecting one from another case but it didn't make a single noise.

All the components seem to work fine in another PC too.

Any ideas what could be wrong? I tried re-seating the motherboard and wondered whether that could have been the issue - there was a problem with one of the screws and it had worn off part of the metal when i had screwed it in and a bit that looked like copper from the board was exposed - would this cause a problem, and if so, what can i do to fix it?

I think motherboards are made up of serveral layers , so when u say.

"there was a problem with one of the screws and it had worn off part of the metal when i had screwed it in and a bit that looked like copper from the board was exposed"

Alarm bells rin in my head,having said that no speaker is a bad job, worst case scenario try it all back in the old case again and see if u hear a post sound etc.

Doh. I can't see there being anything else wrong other than the motherboard

Blooming computers. Wasted a whole day messing around with this.

perhaps that screw is causing the motherboard to earth? have you tried removing that screw?

reset the bios?

I've managed to blow out a motherboard by having a screw earthing it. It was still able to draw power but it wouldn't post afterwards. Permanently broken, had to chuck it

Tried taking the screws out and it didn't help.

Bios reset - do you mean clearing the CMOS?

Another thing to note - i updated the BIOS before upgrading so that it would work with 45nm CPUs but it was working fine.
