Okay, guys... I downloaded a core temperature reader program and my cores are all peaking at like 95-100 celcius!!!
whats going on?! never had this before.
CPU usage is at like 4%.... stopped all startup programs. made sure no spyware or crap was running.
A spring cleaning of your fans and CPU cooler looks advisable. Also check that all the fans still work. Last, if it still gets too hot, renew the cooling paste.
Cleaned it with a ton of compressed air today. Fixed the over heating and ran fine now. Fans were also checked to be still working. Hopefully wont have to renew cooling paste anytime soon.
If dust can take your CPU cooler to in excess of 75 deg. C., then that is a clear indicator that you should get a better CPU cooler! If you are running stock speeds a good cooler will keep you under 50 deg. C (peaks) and if you are overclocking under 80 deg. C. Too much heat can cause crashes and sluggish performance (Intel CPUs slow down if they get too hot) and also reduce the life of your components.
Post what model CPU you have and I'm sure participants in this forum will have various suggestions for you in both the sub-$30 and sub-$100 catagories.
