As I posted in the windows help thread, I cannot install an os onto my computer. I'm currently booting using BartPe, but am desperate to re-install windows xp. I ended up having to resort to getting a copy off my cousin of windows xp pro, as I only had a factory shipped recovery cd for my computer (its an advent). Now, I've ran diagnostics on my harddrive, it seems fine, the temperature seems okay, nothing seems to be wrong (I have the same hardware that the computer has been using for a year and a half) The problems began whenever I was restarting my computer, I was getting the 'your computer was not shut down correctly' screens, and no matter what option I selected the computer automatically rebooted...the only way I could get it to work was by turning it off at the mains for 10 minutes. So, I tried overwriting the files in my windows installation from the cd, (dragging and dropping, I was desperate and I'm not very technically proficient)...after that windows would not start at all, saying it was missing a dll or kernel or something. Now, I cannot get my computer to install windows. I've tried about 3/4 different methods of installation, using bartpe, system recovery, setting up from boot, floppys...but every time I either get a BSoD or the computer automatically restarts and I'm at my wits end. I've just tried again there and the message on the BSoD was 'DRIVER_IRQL_NOT_LESS_OR_EQUAL' with : STOP : 0x000000D1 (0x50726289, 0x00000002, 0x00000000, 0xF76D79B8) USBPORT.SYS - Address F76D9B8 base atF76CE000, Datestamp 41107d62 I'm baffled. Usually the installation will never progress past 'copying installation files'. Anyone?
