I don't know how to mess with the bios settings or anything... plus it was working good till I installed Windows Vista... OS: Ultimate Vista My "specs" are... Motherboard: Asus M2NPV-VM Socket AM2 Ram: 2X1 (2 of them) A-Data Sticks Video: Came with motherboard Sound: Same Hard DRive : 320 gb. Seagate SATA Drive Dvd Rom: Asus Sata Drive It's a dual processor.. if you need more info go ahead... but here's the problem... You know I stayed up readin' it and installing and got itall down... This mornin' when I was finished I was goin' to install windows, couldn't get to there so I changed the order of the boot drives and I was able to. Now I think this might've been the problem.. I left let the comp do it's thing then it restarted right? I accidently hit boot from disk, and I pressed reset. Changed the setting to boot from the harddrive and well it said "Completing Installation" and then the blue screen came on.... At the topit said somethin'g about the IRQL's like less or more, not equally matched or somethin'... Any help pleasee..
