I had a problem kind of like that on my Win98 system...I had the Bymer worm and I deleted some of the files that were part of the worm. But I believe that I also deleted my wininit file...but somehow I fixed it by also deleting all the files that had to do with that program, like, wininit.ini, wininit.bak and wininit.tmp. I have always heard that your computer woulden't boot without the winini files..but somehow mine did.
