Pagefile Problem

I have been using win2k for some time.I recently converted my hard disk(20gb) from fat32 to ntfs.After that i get 2 errors when i start the system.

First one says ur page file size is not enough.For this i increased the page file size.Now its 256mb initial and max is 512mb for each drives(4).

Second one says wins can’t be started due to a corrupt database.
In the msg itself there is an instruction to clear the wins directory and restart wins.I tried and no results.
I tried to uninstall and reinstall it but with no results.

Thanks in advance.
