I have posted on here before with my Dell Dimension 3000. I have been having a general slowdown that I believe is NOT malware related, but then again with the sophistication of the malware writers, who knows? Anyways, I had/have run multiple times all the antivirus online and system scans possible, both from a safe mode and regular mode, as well as running some of the stand alone boot scans from a cd and nothing was found.
What has happened is that everything was fine until I had about 700 MB left on my original 80gb hard drive. Things took a turn for the slower after I started recieving low disk space warnings. With the price of HD's being low I decided to upgrade to a 150gb drive and clone the old one figuring this would solve the problem, which it has not.
Whenever I try to open and explore my file directory, it takes forever, as well as booting up in the morning. IE, Firefox, and MSSE also seem to peg the cpu at whatever they can steal like 98% if one or the other frees up otherwise they alternate between about 87% between them. The slowness is caused by the cpu running at 100% most all the time, or at least when I execute a program. I am talking a slow factor of minutes, not seconds....Please help...Could there be some setting that needs to be reset to recognise the new and larger hard drive by the OS?
