I know this has been talked about but this might be a little different situation. I installed the SATA drive and windows xp normalyl and it was going good for a couple months. Then i dsicovered an older monitor that was bigger so i installed it. That same day i was fiddling with the graphics settings and it restarted. Now whenever i start up the computer it wont let me get into windows. Then when i decided that i was going to format the harddrive, i popped in the windows XP disk and it said that there was no hard drive recognized. I tried the whole F6 thing where i install it via a floppy, but that failed. So can anyone help me?
