I have a Dell Dimension 4100 and it started locking up at random times about 3 months ago, and I had XP Pro installed. Since then Dell has had me reinstall ME, tried 2 new motherboards, a new processor, a new power supply and new memory. Nothing has fixed the locking up problem. They keep insisting it must be a software problem, but this thing freezes at the bios screen or even if i unplug the hard drive and boot off of a floppy it just freezes at the dos prompt. I think I have gone thru every software and every hardware option but can't stop this computer from locking up. I have even taken the computer to different locations and tried it there. Is there anything else you could suggest I try?
