Hey all- Hope I am posting in the correct forum. I just got a new Dell XPS 400 Pentium D out of the box. It came with Windows XP Media. I wanted to install XP pro which I from my last retired PC straight from Dell. I booted to the CD and it did it's normal driver loading etc. Once it went to the next set up screen: Repair - install - quit. I get no keyboard response and it locks up. I went through this a number of times with the same result. I thought it was possibly the PCI-EX video card took that out same results. I TRIED putting the hard drive in another machine with a pentium 4 and it installed without a problem. I did update to service pack 2 then ran sysprep and removed the harddrive installed it back into the original machine and now I am in a reboot loop. I am at wits end. I don't know if this is XPpro issue, a Pentium D processor issue....Has anybody heard of anything similar occuring? Help!
