Problems after removing heat sink.....

Specs: Vista, Athlon 64x2 / 2gb
So I thought I'd finally get around to cleaning my cpu fan and heat sink. I've got an Acer Aspire x1200 desktop with an AMD Athlon 64x2. I removed the fan and heat sink together and the processor was attached. I then cleaned the dust from both and put them back together. I took care in lining things up with the processor and screwed them in just as I found them. Upon booting up the fan started going 90 mph right out of the shoot and wouldn't stop, and a got a quick "no signal" on the monitor.

Thinking that was a freak happening I moved on to my older HP Pavilion and did the same thing (but without the processor coming off) and the result was basically the same.


Any help would be gratefully appreciated!!

To start with, why are you taking off the heatsink to clean it? All you needed to do was give it a good blast with compressed air & maybe a few strokes with a soft bristle brush. And why are you removing screws? Isn't the heatsink held in place with a locking lever? The fact that the CPU ripped from it's socket pretty much says that you're doing things wrong.

Since you removed the heatsink from the CPU, both the top of the CPU & bottom of the heatsink need to be thoroughly cleaned of all traces of the old thermal compound. Once the surfaces are clean, they should NOT be touched. A small dab of fresh thermal paste should have been applied to the center of the CPU, the CPU installed in the socket, then the heatsink set in place & locked down. That's all there is to it. Paste should not be spread out like frosting on a cake, just a tiny dab (unspread) in the middle of the CPU is all that's required. If you did it differently, you did it incorrectly. And YES, fresh paste MUST be used! This is how it's supposed to look before the heatsink is installed:

I just cleaned and installed the cpu and heat sink (as stated by Artic Silver) and various videos. BUT - when it starting up, once again the fan immediately ran at overdrive and I got the brief no signal box on my monitor.

Now what???

I still don't understand why you removed screws that secured the mounting frame in place when all you needed to do was unlock the lever on the heatsink.

See chapter 3:

No mounting frame with this cpu. Fan and heat sink are screwed together and then 4 screws connect that over/to the cpu.
