Windows swap file is damaged

When exactly did you get this error? How often does it happen?

If you have your swap file set at a custom size, try letting windows manage it and see if that makes a difference. Also, run scandisk and defragment your hard disk too to make sure it's not damaged.

Manually change the size of the file to 0MB. While you are fixing the problem your machine should run fine with 512MB of real memory. After manually adjusting the size of the swap file, you will have to reboot.

Then run scandisk (in DOS) and then bott and run disk defrag so that your new swap file will be able to locate in a contiguous section of the hard drive (no fragments).

After running scandisk and defrag reboot and change the swap file back to either letting Windows manage it or to whatever you like. I have always heard 1.5x-2x physical memory. This would be quite a large file for you, 728MB-1.024GB.

If you are unable to change the settings on the swap file, I believe you can still delete the file but I think you haveto do that from a command prompt and no how to identify the swap file, make sure the attributes are set so that it is not hidden,read only, or system. Then delete it.
If the first solution doesn't work then post a comment to get the details.
