Overheating issues on Compaq?

So I made the mistake of trying to fix my laptop over winter break. Thought I could fix a short on the headphone jack, so I took the whole thing apart only to be foiled by an integrated jack. Anywho, that's not the source of my problem.

In order to get to the last screw to access the motherboard, I had to pop off the heatsink of the processor. I thought, no big deal, I'll just slap some AS3 on it when I'm done. Since then, all I've had are problems with overheating (I believe). The gracious minds at ArsTechnica and the members of this very fine forum both offered advice. The first was to place superglue on the corners of the P3 core and use thermal grease to stick the heatsink back on. That didn't work.

So I got some thermal adhesive that came with the Zalman Northbridge heatsink. That seemed to work when I was at home. Now that I'm back at school, nothing much will run on it. I managed to install WinXP on it again, but if I try to do anything, say run Windows Update, it will just shut off until it cools down.

What can I do? Or is it dead?

Summary:

1. Took heatsink off Compaq Laptop processor.
2. Tried to use AS3 to put it back on. Didn't work
3. Tried the superglue trick to attach it with regular thermal grease. Didn't work
4. Applied thermal adhesive that came with Zalman northbridge heatsink. Worked a bit, not anymore.
5. Suggestions?
 
Dude... this is way over my head....
but ur one gutsy guy!
I ll never have the guts to open up my lappy!!

Btw, dell has a detailed manual about how to open up their laptops..

Does compaq have a service manual? Check their website if your havent already...
 
how is the heatsink attached to the CPU?
I am guessing that it is not making enough contact to dissipate the heat. If the heatsink is the screw on type then there shouldn't be many problems, but I am guessing it just help together by glue then?

Also, I wouldn't use Artic Silver inside a laptop as there are way too many electrical connections that could be shorted.

oh, is the fan on the heatsink working?

If everything has failed then there is the last resort of buying thermal epoxy and permanently gluing the HS to the CPU.
