What's the most common cause of the BSOD, and the most common fix? I am in my car right now, so I can't post the error message.
Any help would be much appreciated!
Just run a sector by sector scan of the drive in disk tools, and look at the report. If there are just a few bad sectors then a wipe will get rid of what ever was causing the BSOD. You can even get a boot disk tool to do this or you can mount it in a portable enclosure. There are tools that will really stress the drive if you want to be sure. Look at MajorGeeks.com for some tools.
Lots of bad sectors? Unscrew the case of the drive and see what it looks like and then throw it away. (they are cool if you have never seen the innards close up)
