I've had to repair my hard drive on my HP laptop before.  I think it's got some bad sectors.  I thought the issue was resolved.

Until this morning.  When it would boot, go into the OS and then just... hang.  The screen would go black, etc.  I didn't have time to really look at it this morning, but, looking at it now, I'm doing a full virus scan.  But, I'm REALLY anal about doing the virus scan thing so I don't expect to find anything.  An error briefly came up about DNSAPI.dll, so I think I'm back to the bad sectors on the hard drive. 

Argh!  I'll see what I can do to get it fixed.  The bummer is, I'm giving my little Toshiba Netbook to my daughter to take to school with her so I won't have a backup laptop if something goes hinky with my HP. 

Bah.
