I have an old PowerMac G3 I use for software testing running 10.3.9. Yesterday I was downloading/installing some security update, and the power went out. Today was the first time I went to turn it back on, and nothing happens at all when I push the power button . I tried a few different outlets, but nothing changes. I'm thinking the power supply might be shot, in which I can hopefully buy a cheap one, as I got the Mac for $70 . Any other ideas?
