Keeping the computer cool. Help!

[Jean-Luc]

I think I could be having some trouble guys. Lately, my PC has been getting the BSOD after extended use (seven or more hours running), and when I recently installed Speedfan, I noticed my CPU temperature is running close to 85ºC constantly, and the core temperature of my computer starts at 43ºC and gradually increases as time goes by.

I realize that the CPU temperature is way outside of it's limits, and I was wondering if you guys have any good tips on how to keep it cooler without spending too much money (As in, $10 most is all I have)

You should open the case up and clean the heatsinks.

and make sure your cpu fan is even running, with those temps >_>

Make sure you replace fans that seem to be making any squeaking or scratching noises or at least have them checked out and sprayed clean with compressed air.

Try lowering the clock of your CPU for the time being; if you're overclocked, I'd say a tradeoff of performance for a WORKING COMPUTER is the way to go.

Also, yeah, clean the heatsinks/fans with compressed air, make sure your PC isn't in a place of restricted airflow, etc.
