CPU sticking to heatsink!

Intel 2.4GB CPU (Socket 478), Asus motherboard
After upgrading some minor components I found that the system wouldn't boot. The signal from the mobo indicated there was no CPU. When I removed the heatsink I found the CPU was practically welded to it and had some trouble prying it loose. Once I reseated it the system booted fine.
I figure I can't avoid heat coming off the CPU, but is there any way to keep it from sticking to the heatsink? The locking arm doesn't seem to do anything to keep the CPU seated, and short of replacing the case and motherboard, I don't know how else to cool the system.

Thanks

I believe the thermal compound is a synthetic wax. And waxes stick to things when seated. The way I remove a heatsink is to twist it slightly before lifting it off, that breaks the grip.

heh that's seems a bit too hardcore to just take a hsf off.
A little bit of muskelz should take it off.

I think he mentioned that the CPU socket is not even holding the CPU into the socket the holding arm does not lock it in..............Ok end of story here.
