I am having a major issue. I and trying to repair an older computer (Dell Deminsion 8400) due to the hard drive crashed. Purchased a WD2500aajs hard drive. I installed the XP sp3 and went through all the processes no problem. After it finishes it reboots. Then i get the BSOD saying the file iastor70.sys caused the issue PAGE_FAULT_IN_NONPAGED_AREA...i CANNOT get into any safe mode..i have tried vga mode, debugging, everything..i cant even get into dos...What could be causing this and how can i fix it. I also installed new ram but still nothing. PLEASE HELP
