windows xp pro 2002, sp3
pentium 4, 3.4Ghz, 1GB RAM
148GB harddrive, 101GB free space
When I start my computer and get to the desktop it takes about 10 minutes until I can actually use the machine. During this time the harddrive is running non-stop and trying to use a program like IE or Word is so slow that I just wait until the HD stops running. Otherwise, I do not seem to have any problem with the performance of my machine. I cannot detect any programs running in the backgroud during this time: I don't think it is the antivirus, definitely not the backup utility or windows automatic updates. Disabling the AV does not alter performance.
Additionally, at random times while using the computer the HD starts working and this does not seem to correlate to what I am doing with the machine. For example, I may be using Word and typing a document and for no reason the HD starts grinding away but not in response to a task or function that I had performed. This particular HD activity does not affect the performance though and I suspect that it may be the anti-virus. It is annoying as this machine has a particularly loud HD and always has been loud.
Actions to date.
1. run my antivirus: Spyware Dr. with A.V. Also used Malwarebytes and Spybot. I have a clean machine.
2. run startup utility and disabled various programs which has helped speed start up but not eliminated whatever is running in the background as described.
My questions: 1. what is running after the start up? 2. why the heck is my HD so darn loud?
thanks for any insight with this.
