I've got a client with a reboot loop. When trying to run from the e-machines XP Media Center OS Disc, I get this message. I check the RAM with MemTest98+. It passed 42 times, so that looks good. I couldn't get Seatools to run on the client's computer because the mouse wasn't recognized in the Seatools GUI. However, I pulled the HD out, and put it in an enclosure, and hooked it up to my computer. When I powered on the enclosure, it sent my computer to the same blue screen (Page Fault In Non Paged Area) When my computer booted back up, the hard disk in the enclosure only showed up as a recovery partition (about 10GB). The drive is 160GB. I check in disk management, and the rest of the 160GB shows up, but there is nothing I can do with it. It won't even show it's properties (says something about refreshing the drive list, which I do, but to no effect). I started up Seatools for Windows, and the drive showed up under "USB" but I'm not sure if it detected the whole drive, or just that recovery partition (Seatools doesn't show any drive sizes). Anyway, I did a short scan and long scan with Seatools, and it came up clean. Not sure how to proceed. By the way, I can't get into the OS on the client's drive with any option (Safe Mode, etc.).
