The service person came on Wednesday I believe it was. Replaced the hard drive and was gone in 5 minutes. I held off reconnecting the machine until today Sat. Same thing happened, which makes me think there is something more than the HD with problems. Calling Dell on the weekend I guess is a fruitless deed. To be specific it just asks to hit f1 to reboot, nothing happens. Keeps repeating. I took a look inside in case the video card or something was loose but it is not like it even has a video card. nothing except the ram looks anything like my machine. I guess I will have to wait til Monday. It is for my Daughter when school starts and this is a pain. I had the machine on my work room table when the guy came and when I went to the web page today with my case number etc, it said I was not home user or something like that. I wonder if the creep who did not check anything said because he saw a computer on its side in a work space that I should be changed to a business acct. I just want to get it set up in time for the new school year. To refresh, It is a 2.3 gig dimension. Home xp if it will work. What the ^%^#$# else could be wrong. It worked fine for a few days, then when left on all night it started acting up. Hit f1 hit f1. NaSa. I love my machine I built myself. Not a problem. Knock on wood. <G>
