Sorry if this is the wrong forum or if I've done anything wrong. This is my first post but I have a problem.

I have a MSI Ultra-C 645 Motherboard, 2.4GHZ Pentium 4 processor, 512 DDR Ram, 64mB video card. 450W supply.

I build a computer 2 years ago and I'm using the same motherboard. All other components are new except for the motherboard, hard drive and video card. I replaced all the other parts. The computer worked but coming back one day it just didnt start again and so I put it away for 2 years. Just recently I've been working on it again.

So after I carefully installed anything and turned on the computer nothing happens. No visual no anything. The entire case comes on and the fans work.

My motherboard came with D-Bracket. It's a diagnoses system. Four Leds are on. The manual says that the processor is defective or not installed properly. I know the CPU is installed correctly and it's new so it's not defective.

What can I do to fix my computer. Someone please help, I've invested a lot of money.

Could I have things plugged into wrong spots?

is the new cpu compatible with that motherboard? Just because it is new doen't guarantee it is good...Check everything again.

Yeah the board support up to 2.4GHZ (Pentium 4) and in the manual for the motherboard.

i agree...just because it's new does not mean it is not defective.

Since the diag lights are telling you that, I would believe it.

You can remove the CPU and check it for bent pints or burn spots, but if you do, make sure you use some heat compound when reattaching

i agree with gerryf and austin- make sure the cpu is not a bad product- some types of defective problems you can fix- minor ones tho, if it is complelty gone you would want a new one...for a pin, just carefully take a pen and push it back into place
