@Luckystar, I'm running that scan now... Thanks for the help. Will let you know what happens.
@Hopalong, yep I've tried a system restore already. No joy.
I have a funny feeling that plugging out my PC while it was shutting down caused some damage on the inside of the machine itself. The PC doesn't detect that there is a Windows 7 CD in my drive even when I set my CD drive to boot order number one. The data coming from the hard drive sounds a little funny. Kinda like a stop and go. Also when I'm playing music from either Windows Media player or ableton, the audio starts and stops. As if the data isn't being read in fast enough...
