Excellent guide !
Great guide! Powered down computer prior to vacation and came back to find it non-operative. This guide, about 90 minutes, and a $50 replacement power supply off of ebay and it is back up and running. This is a secondary computer we don't use much any more, but I hated to throw it out when it was still working for what we were using it for. Thanks so much!
