You will need to install all your drivers, motherboard, graphics card etc. Did you get a disc with your PC or did you get a repair disc of some sort.I would imagine the F drive you have is a hidden partition which will allow you to reset your PC to when you first got it.
Your user manual should tell you how to do this. It maybe that you had to create your own repair disc when you got your PC. If you did not do this it will mean going to the PC manufacturer's website and downloading the correct drivers.
