Drastic Speed Differences Between Identical Machines

[bobber205]

We have two IBM ThinkCentre pcs where I work. After doing some routine maintenance, I discovered that one of the computers is ungodly slow.

I thought maybe it had some weird virus, so I did a clean XP install. Was still just as unusably slow.

I even doubled the ram. Barely any effect. What's wrong with this machine?

First hit control, alt, delete and se if anything is pinning cpu use. You can arrange the cpu field with the most % usage at the top by clicking on it at the top where it says cpu.

I'll do that asap.
Right now it's beign installed with a ghost image. I've looked at the cpu usage before and it would typically be under 20% or so.
It's so slow that I could move a window around the screen and the cpu usage would jump to 100%.

Check the BIOS settings. Maybe someone messed with the DMA settings and now all the drives are running on PIO mode lol.

Could be bad RAM too, it might be worth swapping it with some other RAM and seeing if that solves anything.
