Mouse Problem w/ Windows 98 SE

[Santa-Jack]

I recently acquired a few Toshiba Equium 5160D PCs with the following specs:

Pentium 166
64 MB RAM
WD 644A Hard Drive (Some have Maxtor HDs)
Toshiba Floppy & CD-ROM
Integrated Intel NIC/ATI Video/Crystal Sound

I am running a fresh install of Windows 98 SE on them but have run into a problem with the mouse. When the hard drive is being accessed, the mouse cursor moves really slow and jumps across the screen when I move it. I have not been able to figure out exactly what the problem is or how to fix it. Any suggestions would be greatly appreciated! Thanks for the help...

Slow computer and not enough memory.
If the hard drive is being accessed when your not doing the accessing, your running low on memory and windows is now using the swap file on the hard drive.

I am running 98se on an old K5-100 and 32 megs of ram for my daughter's educational software with no mouse problem. Imperion is correct IF you are running any memory hungry or heavy graphics programs. If not, look at IRQ sharing and be sure someone hasn't got the mouse sharing with anthing else.
