From the description it does sound like the hard drive is failing when it is warm and works again when the system has cooled down. You shoud check the fans are working and that there are no obstructions to the air vents on the case. Other than that you may need a new hard drive.
Please refrain from using any P2P program as they are a guaranteed way of infecting a computer.
