Finally I have a problem where I can''t make heads or tails from. I have a very old Pentium II computer, using Windows XP which I use as a music cumputer. It suddenly stoped working. What it still does is booting: it finishes POST operation, checks BIOS, recognises that keyboard and Mouse are attached, it correctly sees my hard drive and cd-rom drive. Then it switches to my hard drive and is supposed to start windows, but it just gets stuck there, giving me an ugly black screens with a blinking cursor and that's all. I've tried reinstalling Windows from CD and that works fine until it restarts and the hard drive is supposed to take over from the CD-ROM. It gives me the same screen. The silly thing is that up until that moment the computer has been copying files from the cd to the hard disk, so the computer is able to work with the harddisk. I've checkdisked the HD and everything was fine. I've placed the HD onto another computer and it was able to read the HD,, so the HD is OK. I've repeated everything with another HD with exactly the same results. So, the computer is working, nothing wrong with the MoBo, the HD is working, cables are fine (I've replaced them as well), computer is able to work with the HD, but it just won't work when windows is supposed to start up. I've a;so made sure that the master/slave jumpers are ok, so that's not the problem either. HELP ME, SOMEBODY!
