I've been on holiday. I come back, the PC is buggered.
The one that used it while it was gone said my (unused and uninstalled) D-Link wireless network card popped up and installed, but asked for the CD. They turned off the computer, and thats all I know about that.
Ever since, it won't boot up past the Windows XP Splash screen. I've tried a repair off of a Windows install disc, and a Linux live disc can read (although not write/copy from) my NTFS partitions, so I can't easily back the stuff up without wasting a fair few DVDs, and a lot of time. Before going to the XP splash screen it also brings up the boot menu, giving options for Safe mode, Safe mode w/ networking, Safe mode w/ command prompt, Start windows normally, and Start with last known working settings, none of which work. It just reboots after the splash screen and loops around like this till I do a hard reset.
Windows will not boot at all.
Looking for any help before I lose a fair amount of unbacked up stuff through reformatting.
Just noticed its most probably a software issue, but the hardware seems to have died to begin with. Ah well.
