My computer's broken =(

I left my computer on while I left to work or overnight, I don't quite remember which. When I tried to use it again, I hit the up arrow to wake it up, and it came on with a screensaver that wasn't moving... So I power cycled it, and it tells me the bios version, checks the hardware, then says Loading GRUB... then goes back to the beginning, checking the bios and hardware again! It makes me sad, I miss my computer. I have a lot of saved settings and such, and in fact the thing I miss most is my RSS reader (Flock) all configured and knowing what I've read and such... My husband is going to try to fix it, mmhmm.
