I dont know if this option is in 2000 but worth a look.
Right-click My Computer, and then click Properties. On the Advanced tab, click Settings under Startup and Recovery. Click to clear the Automatically restart check box under System failure, and then click OK. The error message on a blue screen should remain on the screen so you can record the error information
The log files that Andy SD refers to can be accessed in Windows 2000 by going to Control Panel, Administrative Tools, Event Viewer.
By default (unless you've changed it) a fatal error which causes the computer to reboot should have been logged. Should be under System log in event viewer.
Usually there's a red cross (for error) against it. You can also check the time (think what time it crashed the other night). Double click the item, and see what it says. Unfortunately it's usually gobbledegook, but it may help.
After you've changed the Startup and Recovery settings as suggested by AndySD, next time it crashes, you'll see the blue screen of death with the error message. Write it down (although it will also be logged in System Log).
Hi, my system started doing this while running XP.It had been running faultlessly for months. Turned out to be the my 450watt Qtec power supply! I use to run the PC with the side cover removed and in a fit of tidiness put it back on. The old PS had previously ran with the covers on with no problems, so I though my Qtec with it's twin cooling fans would be fine.....wrong!Once the system was running for about 30mins the bios reported ps voltages were flittering about between 11.2 and 11.8v! I took the case side panel off, voltage stablised at 12.4v and I haven't had a problem since :) I will be fitting a case fan and trying again soon. Took me ages to find the problem, at one point the PC restarted about 6 times in two hours. It might not be your exact problem, but perhaps overheating of somekind is? Have you made any recent changes or even moved your PC?
no, but im wondering about my hard drive. Its an IBM and makes random noises from time to time. But the other night it made one of its noises last night then a few mintes later rebooted. So im gonna go have a nose round the IBM site.
