Compaq recovery help

Before I make a big bang boom stunt I need a small. This old ass pc has been being retarded these past days. The keyboard stopped working even though the light still turns off. And F drive stopped working, so I cant burn or upload the recovery cd. The E drive cant really do what the F does. And on top of that it says my sound device is being used by another system or not even installed when I try to listen to music. My control pannel says there are no programs installed to the pc. This all happened after I came home from school, when in the morning it was just fine. Is there still another way to restore the pc?
