Computer won't work after CPU re-seating

[heliotrope]

So a friend wanted his fan fixed (i oiled it) and heatsink cleaned. Simple enough, pull the heatsink and wash it up, and oiled the fan and put tape to seal that up. Cleaned both surfaces with isopropyl alcohol, add thermal paste, started placing the heatsink back on. My screwdriver slipped though putting the bracket back on, and now the computer will turn on but no POST.

I fear for the worst, even thought I have looked at the motherboard near where the screwdriver slipped and am unable to see even the slightest of scratches! Perhaps I need to take a magnifying glass to it, but to the naked eye with a flashlight there is nothing chipped or scratched visible.

I even re-seated the CPU just to check I hadn't damaged the core (It's an old socket A Duron CPU). That looked good though.

Anyone have any suggestions? Is this for sure a motherboard problem, even though I can't see any damage? Thanks for advice.....

id check all your connections, make sure you plugged everything back in, it is possible you broke a trace and maybe shorted the motherboard.

does it smell burnt?


if it still does not post you might have to pull all the cards but the video, and maybe even reseat that to see.

how did oiling his fan fix it?

those old chips run really hot and if the heatsink was not making contact it could have fried.

if it is dead, you can score used durons and tbirds for dirt cheap, and new durons and some xp's for cheap. not sure what setup he has.

I broke a socket A AMD 3000 when I slipped w/ my screwdriver putting the heatsink on. Tiny scratch on the green part of the CPU. My guess is you busted the CPU.

look closer on the PCB of the motherboard - it doesn't take much to cut through traces on the PCB - I've sadly done it in the past - and I think about it everytime I stick a screwdriver near the motherboard

this is why i dont touch or help any of my friends and their computer problems. i think you should reseat everything first before you flip out if worse comes to worse you fried the cpu-but thats quite ODD!

Do you hear any beeps when you turn on the computer? I'd never clean the cpu surface with alcohol because that doesn't sound very safe for it. You may want to swap out components to see what is causing the system to not POST.

I've hit the pcb of my motherboard many times on Socket A motherboards because my screwdriver would slip out of the clip often. I guess I'm lucky because my old Socket A motherboard still works.
