Major Computer Trouble

After many tips and hints sent for me, I've been waiting to takes as many notes as possible. But, my computer is running VERY slowly, and freezes very often, and getting crashed very often. Darn those blue screens of death! The main of my computer problems is my hard drive is not functioning well anymore. So, I'm waiting until practically at the end of the month to buy a new internal hard drive to make my computer running properly again.
