I say you just trade your PC, for your Dad's PC, and to hell with it.
You might to go into your BIOS and see if its doing anything at start up that it doesn't need to be doing. Also check to see what is starting up with your Windows load.

Immortality is your last hope.
For my existence to be true, Hell's Fire must burn hotter then Heaven's Cold Gates can stand.
