System won't boot after video card replacement
Replaced the GPU in my 24" iMac, following a number of web resources. No the machine won't boot. The pilot lamp (lower right corner) comes on, and at least one of the fans runs, but no screen backlight and (apparently) no HDD action. With the bezel removed, I have one green LED just above the memory slots, so I believe the Power Supply is OK. I've had the bloomin' thing open half a dozen times, looking for something I forgot to reconnect, but there don't appear to be any empty connectors. Any suggestions on what to do next?
Esta é uma boa pergunta?

After reading through a bunch of questions & answers here, I tried the CMD+OPT+Q+R startup and, lo and behold, I got a chime, backlight, and the system looked like it was starting to boot. Went through the grey screen, to the blue one, then... blank again. Do these new symptoms point anywhere?
