Booting up this morning, Lab B 19 went into CheckDisk. It eventually completed the bootup successfully, but this may be a sign of a dying HD. Station 21 booted up at 800 x 600, and when I logged in to change it to 1024 x 768, it seemed to lose all communication with the monitor for a couple of minutes before coming back with a wobbly picture, then settling down. Watch this one in case the monitor is on the way out.
