Hi~

I'm working on a Dell XPS 200 in which I just replaced the power supply. After installing the new PSU, now neither the keyboard OR mouse respond. The keyboard is responsive when I go into the BIOS setup, but when I get to a logon screen neither the keyboard or mouse works. I have tried:

1) unplugging the keyboard and mouse, unplugging the power cord, and pressing the start button to drain off the capacitors and hooking back up and restarting.

2) checked the BIOS settings

3) replaced the onboard battery

I don't know what else to check. The machine is barely over 2 years old, so I would like to think the MBO is OK (but then again, the PSU went out rather quick). I don't have theoriginal XP install disk, and an enterprise XP install disk I have won't boot (seems like the CD drive will not read it on startup, although I can see it in the BIOS). Do I need the orignal dell disk to do an XP repair, and since I don't havr it, then what?

The BIOS version is A004.

I'm at my wits end trying to get this thing going. Any help?

Thanks
