Well I ran accross a Dell Dimension 4400, its pretty new compared to some of the stuff I repair but this one is really boggling me. I can get the BIOS to post but when I try to boot off of an OS CD to install it…I just get a blinking curser in the upper right, than the it freezes. I can get into Fdisk and play around in the BIOS but I cant get an OS to install. I can partially install windows 98se but XP wont right from the get go. I have systematiclly replaced every part I can including trying to boot with only the bare bones but still it wont. I am thinkin its the mobo but that is still a bit strange since I can still play around with basic stuff and format drives. Any help?
