I am not 100% sure this belongs in hardware as this may not be a hardware problem. If it doesn't notify and move this thread.
I just Finished doing an install of an older computer and the only problem I am having this run through is that the mouse leaves a trail of cursors as it moves. It only occasionally refreshes.
Note: Had to do the alternative install, with the other on I kept receiving ubi-partman failed returned error code 10.
Hard Drive: 640gb (split between two drives 320 each)
CPU: Pentium 4 (I think its an earlier one)
Graphics card: __________________ (I believe the part number is g7700.2 and its a gateway computer)
Note: It was just recently upgraded from 20gb hdd and .5gb ram.
