FC 4 behaving wierdly

Something is wrong with my installation of FC4 64-bit installation. I'm not sure what it might be. Either my CPU is overheating and the processor is being throttled or there is someservice that keeps causing to behave erratically. This usually happens when I'm browsing with Firefox. Could it be that 64-bit firefox is causing it? Update: For some reason its working fine now. WTF? Category:Tech
