Mobile Processor Help

Did you...
verify the CPU is seated properly?
verify the RAM is seated properly?
verify all cables are plugged in securely?
verify cables are not pinched between solder points on board/chips and casing?
verify you didn't scratch the board/s removing screws or putting back in?
verify you used all screws removed?
try putting the original CPU back in?
try putting the original RAM back in?

A little paste off of the primary chip shouldn't be an issue unless it was making contact with pins or other metal leads. The tops of the chips usually don't have this.

Not Electrically Conductive:
Arctic Silver 5 was formulated to conduct heat, not electricity.
(While much safer than electrically conductive silver and copper greases, Arctic Silver 5 should be kept away from electrical traces, pins, and leads. While it is not electrically conductive, the compound is very slightly capacitive and could potentially cause problems if it bridges two close-proximity electrical paths.)

Hopefully this can get you pointed in the right direction.

I replaced the old processor and it changed nothing.

It sounds like everything is working just fine, there's just no video.

check to make sure the video card is all the way in, with any necessary
cables I.E. ribbon cables... also, that can be due to incompatible memory, try swapping that back to old.... but the most important thing in trouble shooting, is to do one change in hardware at a time.

Just tried a VGA cable to a monitor. Nothing.

Edit: And new motherboards are $140...

I seriously hate my life sometimes. Nothing ever goes right.

My only guess is that I somehow damaged the GPU... which is just a ridiculous notion. Yet, I see no other possibility.

Can thermal paste damage a chip? I mean, I used a tiny dab. Smaller than a pea. It looks like it still went over the edge of the chip itself, but only by a smidgen. So would that be enough to damage it?

as i mentioned, i would check above, because that can lead to both.
if neither of those work, i'd look at outlaws suggestions. sometimes, its the littlest most stupid thing...
