Sounds to me like a bad hard drive or else corrupted system files.
If you're able, I suggest this series of steps:
[ol][li]Remove the hard drive, grab what data off via another computer (if the data is important).[/li]
[li]Put the hard drive back in the laptop.[/li]
[li]Download utlimate boot cd.[/li]
[li]Boot from it, and run various HDD tests to see if the HDD is failing.[/li]
[li]If passes all tests, then it
may be okay.[/li]
[li]If HDD is dead, or if you aren't sure... or if you'd rather just go ahead and get a faster drive anyhow, this is my particular favorite laptop hard drive, currently (assuming yours is SATA and not IDE:
2nd favorite:
Interesting note: price has INCREASED on those drives both at NewEgg and Amazon. NewEgg doesn't currently carry the one with the free fall sensor. Both come with a 5 year warranty.
If you have an IDE hard drive, then any of these should work just fine:
I've installed the 2 SATA drives by WD in 3 or 4 laptops besides my own. I installed the one w/o the freefall sensor in the others, the freefall sensor in mine. The only reason for the difference is that I didn't know there was a model with freefall sensor when I installed the others - oh well. With EVERY install so far, the drive has been extremely quite, run cool (for a fast hard drive), and every system has just JUMPED to tasks - well, not literally of course!

[/li]
[li]Reinstall the OS - easiest fix, anyway, and probably quickest, assuming you don't have TONS and TONS of custom software configurations to carry out.[/li]
[li]In the end, it wouldn't hurt after the reinstall (unless you prefer to reinstall everything manually each time) to use Acronis True Image, or else Norton Ghost, to create a system backup, so you can always just go back to that backup quickly if anything such as this happens again.[/li][/ol]
Oh, on the hard drives, you CAN get cheaper drives, but the absolute most you'll save will likely be $30 or $40, and they'll have a 1 or 3 year warranty vs 5. Choice is yours.
