Windows Vista won't start up, can't repair itself, no boot cd.

Hey folks. Just went to turn on my Del xps410 desktop running Vista, and it decided not to start up/load. Windows Repair wasnt able to fix the issue, and upon checking out the details, it mentioned Hal.dll was corrupt (only stated that a couple times, other times say it wasnt able to figure out what the problem was).

I don't have a backup disc, so I'm not able to go that route. Any suggestions on how i might be able to fix this without reinstalling windows?

Thanks!

 

Thank you! I'll give those a try and report back asap.
