Fried CPU

My CPU began overheating for no apparent reason recently. In the time it took me to figure out what was going on, I'm pretty sure some permanent damage has been done as I'm getting blue screens now every once in a while. I'm not sure what to do--my heatsync and fan appear to be working properly and I have extra fans on the front and back of my case for improved airflow. Still, the CPU idles at around 60C.

What should I look into replacing? Just the CPU? Motherboard as well? A new case? Any ideas as to what's going on?

Well if you idle at 60C that's a bit hot, it's likely to go over 75 under load which isn't all that good. You could be getting the BSOD when the CPU pass 70C as it starts making some error.

What brand of CPU is it? some have different temp. threshold

Also regular maintance that I do with my computer include, vacumming the case, check if you can tuck away cable away from the HSF (Heatsink/fan) also try to have a clear path between your case's fans.

You might need to replace the thermal compound also...again depends on what kind of CPU it is. I just changed mine yesterday. If you can still boot there's a good chance nothing fried and is in working order.

Hey, are CPU fans supposed to blow towards or away from the heatsync/processor?

Also, it's an AMD Athalon XP 2700+

away...

Are you sure or are you just saying that based on common sense?

I'am saying that as having built several computers.

Heat sink fan blow TOWARD the heatsink. That's the best way t o push the hot air that otherwise would stay between the fins.

There aren't many HSF on the market that pull air from the HS unless they are designed that way. I'm pretty sure that since the OP asked he own the standard kind which push air to the CPU.

Ok...I guess my Vantec Aeroflow which have been keeping my overclocked AMD2500 under 40C idle is going backward then.

Most HSF that pull air have a shroud around them to stop the case air from rushing in...when you pull air you essentially create a vaccumm. When you push air you give it momentum and are able to direct it onto the CPU.
