*beep - beap - beep - beep* would be graphics
*beeeeeeeeeeeeeeeeeeep* would be RAM or Processor
sometimes for unknown reasons USB items have been known to make computers do that, also CD rom drives can.
First suggestion, reset ur bios. (little jumper on ur motherboard next to the cmos battery move it up two pins count to 15 then move it back to original location)
failing that, throw it at a wall.
