There are many reasons a processor runs slow. Mine does slow down often. It was built that way here.
1) If the computer does not need speed it slows down saving electricity. Check power options as Windows can have differing power options and hence slow processor and put disk drives to sleep and many chips on the mother board.
2) dusty processor, the temperature sensors have slowed the processor to stop the chip frying. Dust in the heat sink fins causes this. Solution vacuum it and dislodge dust with a small stiff paint brush.
3) Incorrect setup or incorrect power setting.
4) I assume you do have the correct setup CD/DVD ROM and it is set up and rebooted?
