Ok, I shut down my computer this afternoon to install a new VGA card. I upgraded from an ATi x700 Pro to a Diamond ATi HD2600 Pro SB edition that I picked up off of cragslist for $50. So I shut it down, swap cards, reboot. System hangs @ mobo (press F2 for BIOS) screen. Hear random chirping from the drive. So I unplug it, system boots up fine (the 500 has all my movies, pictures and music on it). I lef tthe power cord hooked up but disconnected the SATA cable, system runs fine, and drive still chrips once every 20-30 seconds or so. Anyeone have any ideas? ANy idea how to save everything?
