When i got to install Windows Vista : it loads the files , then comes up with a bluescreen that says :


** STOP: 0x00000050 (0xCAA9FC4D,0x00000001,0x8515AC58,0x00000002)
 454adb
**           acpi.sys - Address 8515AC58 base at 85142000, Datestamp 549adb7



I dont know why this does this, the only thing i can think of this happening is because the disk has scratches.
