System has Win 98, when I reboot, microsoft registry checker starts running and proceeds to rebuild the system registry. How do I stop this from happening. Thank you.

This problem can occur if there is defective memory in your computer. A defective memory chip may damage the registry in memory. The Windows-based (or protected-mode) version of Registry Checker (Scanregw.exe) scans the registry in memory for damage.

When this issue occurs, Scanregw.exe detects that the registry is damaged in memory and marks the registry as damaged so that the real-mode Scanreg.exe is run the next time the computer starts. Scanreg.exe may not detect any damage if the defective memory is not used in real mode, and may allow Windows to start normally.

There are two methods you can use to identify whether defective memory chips are causing the problem:

Method 1

Remove or replace memory chips in the computer to see if the problem is resolved.

Method 2

Try limiting the amount of memory that Windows uses. If limiting the amount of memory that Windows uses resolves the issue, the problem is a defective memory chip. To limit the amount of memory Windows uses, follow these steps:

1. Restart Windows in Safe mode. To do so, restart your computer, press and hold down the CTRL key until the Windows 98 Startup menu appears, and then choose Safe Mode.

2. Click Start, point to Programs, point to Accessories, point to System Tools, and then click System Information.

3. On the Tools menu, click System Configuration Utility.

4. On the General tab, click Advanced.

5. Click to select the Limit Memory To <n> MB check box, and set the value to 16 megabytes (MB).

NOTE: Limiting memory to less than 16 MB may prevent Windows from loading. If you are unable to start Windows normally, start Windows in Safe mode and then disable this option by pressing and holding down the SHIFT key throughout startup.

6. Click OK, and then click OK.

7. Restart your computer normally.
