My rig's a Dell/ p4 3.20Ghz with 2 gigs of RAM I keep it really light on programs, basically just used for trading and lightduty surfing and general use. I de-frag regularly along with regular maintenance. Over the past 6 mos. the CPU has been regularly maxing out 100%, even for run of the mill tasks. Example: I downloaded NERO ok, but when I went to install the package, it took nearly an hour with the CPU redlining almost the whole time... this seems to be happening all the time, even with the simplest of applications. And I'm not talking off the internet 'cause the applications have already been downloaded. Also with no other apps running in the background. So although at one time, this was a smoking fast machine, it's not so much anymore. I've never heard of a processor getting "tired" before, but it sure seems like the case. Do I need to upgrade?
