So much for my fail safe plan...if the computer at the head of the pack fails Main computer, Abit IS7-M Pentium 4 2.8G 1G 120/160/750 ext, using on board graphics and networking absolutely refuses to boot or anything. Power supply appears to be working, power and hard drive lights are lit steady. MB has a green and red light on simultaneous, no beeps, no flashing lights. CPU and box fan are both operating. Abit's site appears to be down...are they still in business? Any clue is to where to start diagnosis? Systems been rebooting almost nightly, wasn't sure why, but that led to the feeling of needing to increase my backup capability. Recommended replacement? Computer is used for amateur photo processing and storage, general household uses, every other computer in the house is backed up to it. Main printer is attached to it. No real heavy usage, and it has been adequate, until I started doing photos. It has also been rock solid performer for three+ years. I don't think this is the appropriate time to be buying a mac...was seriously thinking about it with my next upgrade, but it's going to have to be planned.
