Today, when I booted my pc it hung during the bios boot.  I tried it again several time and it just froze at the exact same point (there’s a percent loaded display and it failed on the same percent every time).  I can feel vibration from my hard drive working, while it’s frozen.  I also tried unhooking the power and waiting a few minutes, to no effect.

Then, since the bios display is where you have the F2 to go to setup and the f12 to go to diagnostics, I tried hitting F2 when it was frozen.  But instead of going to setup, it skipped to launching Windows.  And then the pc seemed to run normally.  I’ve been running virus checks and hardware diagnostics all day, but I haven’t found anything funny.

Oh, I should mention that I haven’t installed anything on my pc lately.  There was a Microsoft update a few days ago (so I have a good backup point, in case this turns out to be software).

I haven’t shut it down in case I can’t get it back up again.  Any ideas?
