Unhappy CPU at 100%, Fan always running, Computer Slow!
I've just joined the Forum as I'm in dire need of assistance. I've wasted too much time on this computer waiting for the screens to appear. OK, enough venting - here's the specs:
I have a Dell Inspiron laptop with a WindowsXP operating system. Over the last few months the system has been incredibly slow, the fan is always running and when I check under the Windows Task bar the CPU is at 100% with the largest culprits being explorer.exe, iexplore.exe and svchost.exe.

I recently purchased an external hard drive and restored my computer to the manufacturer's setting so I could start fresh. I've only added back things I need. I also installed McAffee security. I wondered if I should download a registry scan to see if that will help but I'd really appreciate any suggestions before I head down another unknown path.
Thanks so much!

I don't know about the processor at 100%, I wonder if it is possible that you have malware even after fresh install. Was it from recovery partition or discs? But I did use a vacuum on the inside of my very old computer a couple of months ago because my fan was running constantly, and would only shut off after a restart. After vacuuming out a TON of dust, the fan has stopped running constantly "for no apparent reason" (translation: overheating, i guess)
