dropped my desktop. The processor fan and chip assembly came loose, actually popped off the pins. Re-installed them, there were no pins damaged. computer does nothing on monitor, its black when I fire it up, but the fan is running and I can hear the hard drive working, but not like usual. Could my hard drive be jacked, or could the processor have been damaged? can an impact scramble a processor and a hard drive? Is there anything that I can do to test this or do I just need to carry it to a shop? The local shops are a rip-off!
