I have a Dell Inspiron PC with Windows Vista OS. Recently, my PC began running very unusually slow, and the fan is always on which leads me to believe the harddisk is constantly working, even when I'm not doing anything.
I've run AVG SUPERAntispyware, ERUNT, Malewarebyte's Anti-malware to no effect.
Curiously, when I started the Disk Defragmentation software, six hours later it was still "defragmenting" and it never would finish.
Finally, I ran the Uniblue RegistryBooster which said I had a bunch of registry errors, but doesn't correct them. It seem more interested in selling me something than fixing anything.
Any thoughts of where I can go from here?
