Q: G5 startup light flashes 3 times then after a pause flashes 3 times etc.

Loretta,
I also feel bad about my dying (dead?)G5. I bought it from Apple as a refurbished unit and paid $1399 plus tax for it. Over the years I have purchased quite a few Macs: Two Mac II cis, two beige G3 desktops, a G4 Power mac, one G5 power Mac, Two Mac Minis and a Mac Pro. One Mac II ci and one beige G3 desktop were purchased new all the others were refurbished. The Mac II cis and the beige G3s were still running when I took them to the junk yard. All the others are still working except for the G5. I never had to have any repair work done on any of them. What I'm trying to say is that yes you do expect a computer to work flawlessly for many years but then there are going to be times when they don't. That's going to be true for any make of computer. When your computer dies after 6 years you just have to move on. You said that you paid $3700 for your setup. Since the original price for your G5 was $2500 then you must have purchased a very nice monitor at the same time. That monitor will still work with a new computer. If you're mad at Apple then buy a new Gateway, Dell, HP etc. for about $800. It will out preform your old G5. Check out newegg.com. If you still like Apples then consider the new Mac Mini for about $700. You can still use your old monitor, keyboard and mouse with it. I got a refurbished iMac from Apple to replace my wife's G5 but that's because the G5 had a cheap 17 inch ViewSonic monitor. I might add that several of the Macs that I bought were for my kids - I don't use them up that quickly all by myself.
