Extremely slow pc

Dell / DIMENSION 3000
May 14, 2009 at 10:39:02
Specs: Windows XP
I am working on a Dell Dimension 3000. It came to me as being unusably slow. I stripped it down to the vitals and still slow. So I reloaded xp and still the same. I notice the cpu usage pegged at 100%. Any suggestions on what coudl be causing this? Reminder I am working with a newly reloaded os so there are no other programs installed, no virus program or anything. This thing literally takes minutes to respond to a mouse click. Help!

It would help to list your system specs. We have no idea what you have installed.


What did you use to load XP...the Dell CD's or a Microsoft CD?

From what I can see it's a stock 3000. I used a Microsoft xp system disk and downloaded the drivers from Dell.

It is a given some one may disagree but I would first suspect the hard drive.

Taking to long to seek....May not chatter or have any bad sectors but sounds like the seek time is going. ( There is a little arm inside that goes back and forth looking for information)

How long did it take to format when you loaded xp? The format time if too long is usually an indication of future problems.

Then the cables and the memory.

I would transfer the os onto another hd even a small test hd and see if if changes.

Hope this gives you some ideas on working through this.

If you suspect the HDD, run the manufacturer's diagnostic software.

Will "dell online pc check up" work after you've installed a standard version of Windows?

The only other think I can think of is your CPU is overheating. The Pentium 4 will throttle back once it reaches a certain temp. Does the Dell BIOS have hardware monitoring?

Check device manager to see if you are running in a DMA mode on the HDrive controllers. Although that wouldn't explain the slow install.

I can't seem to check anything. Each click literally takes about 5 minutes to complete. I hate to give up but maybe I should tell this customer to junk it. I'm wondering if this cpu overheated at some point would it act like this? I found a bunch of dust on the heat sink when I first got it. I have also tried a known good psu so I seem to be down to the board or the cpu.
