overheating problem coz heatsink

[pankaj4687]

im using p4 3.06 ghz with nvidia 610i mobo
my processor temerature is 65c for idle and 75-85 during heavy use
and i think after 80c-85c pc turns off due to overheating
i think this problem is bcoz of my heatsink is not properly mounted coz its 1 latch out of 4 is broken

so guys whats the solution
new heatsink or any other solution plz help

and also tell me price of heatsink if possible
my local vendor is giving me new intel heatsink for 500 and local branded fro 200 which should i buy

Don't ignore Overheating problem. Get the Intel Heatsink itself. 65-75 C is normal for any processor I guess.
