I'm not seeing anything that's pointing specifically to a hardware failure, so I'd suggest that the problem is likely software. Next step would be to try booting off another source. And external hard drive, or an install disc if you have them. Just boot off something other than the internal hard drive. If it works fine from another boot source, then you will need to backup your data, and reinstall your OS. Note that a faulty hard drive may be the root cause of all this, and may need to be replaced. If is has the same issues even from another boot source, then your issue is hardware, and you'll need to have it looked at by somebody.
