My computer shuts down without warning several times a day. I checked Event Viewer, and this error (see pic) coincides with every shutdown. There may be a link here. But why would this cause the error? What should I do? There is no CD-ROM in the drive when this error occurs. Link to picture: http://img131.imageshack.us/my.php?...

First disable XP's automatic restart feature. 0. Navigate to the Control Panel in Windows XP by left-clicking on Start, followed by Settings and then choosing Control Panel. 1. In the Control Panel window, open System. Note: In Microsoft Windows XP, depending on how your operating system is setup, you may not see the System icon. To correct this, click on the link on the left-hand side of the Control Panel window that says Switch to Classic View. 2. In the System Properties window, click on the Advanced tab. 3. Locate the Startup and Recovery area & click on the Settings button. 4. In the Startup and Recovery window, locate and uncheck the check box next to Automatically restart. 5. Click OK in the Startup and Recovery window. 6. Click OK in the System Properties window. There is a possibility that the optical drive is hosed & may need to be replaced - so keep that in mind. However, I strongly doubt chkdsk has anything to do with the issue.

i'd change the power supply. i fixed one yeaterday that did the same thing

Shut-downs can be caused for "all manner of reasons" (including overheating) but this one appears to be pointing to the CD-ROM. I wouldn't rush out to buy a new PSU just yet (see #3) just because it happened to be the reason for restarts on one other machine. DerekW

Hi Try to open your PC and check the CD cable if it is good connected to the motherboard Good Luck

While you are checking the cable in post #4, be sure to get a can of compressed air and blow out your processor fan, power supply fan, motherboard and case vents. Most computers should be cleaned yearly .. those with dual core processors should be cleaned every 6 months. You computer manufacturer generally provide's instructions on exactly how to do this and how often.

Update: I noticed that the main fans on my computer are beneath the laptop, with only half a centimeter space between the fans and the desk. I placed the laptop on a wire cooling rack to give it more space and it hasn't shut down by itself in 2 days. So far so good. Looks like a heating issue.
