Observe carefully for what type of noises you are hearing. It is quite possible that the CPU heatsink fan is bad. This will prevent the computer from booting. Let us know what happens when you re-boot. m 0 l smokarz March 30, 2011 2:09:24 AM well, i opened up the computer, used a whole can of air compressor and removed a tons of dirt from inside. powered on, and the pc is running as it should now. and really quiet too. my kids probably abused this thing pretty good. thanks for the response ubrales, issue resolved. m 0 l Can't find your answer ?
