So I recently upgraded my Gtx 560 se to a Nvidia Gtx 660 ti for my computer and whenever it is plugged in the computer peripherals will start up really fast. The monitor shows the log in screen for a second then the computer will begin a cycle where it powers on like 10 seconds,(the keyboard and mouse light up, the monitor shows signs that its about to display something) then everything powers down and it restarts.
