I had my IIsi up and running this morning. I just finished recapping the logic board and PSU yesterday, and everything was working great. Up until this point I have successfully booted it 10 times or so. This morning as it was running, a breaker in my home tripped and took out power to the machine. This particular breaker in our apartment has a tendency to trip for no reason, so I think the trip was probably not caused by the computer. Looking at my power strip, I thought it had a surge protector built in, but I don't believe it does.
After that, when I turn it on I get the startup chime, followed immediately by the death chime. There is no video activity, no HD activity. I removed the NUBUS video card and RAM SIMMs and there was no change - still just the death chime.
Edit: after sitting for a few minutes I tried again, using the internal video rather than the NUBUS card. The machine powered up, but there were evenly spaced horizontal lines on the grey happy-mac screen. It moved on to the Mac OS splash screen, and it looked a bit off, there were some odd artifacts. By the time it loaded the desktop background and got to the "you might not have shut down correctly" screen everything looked fine, though I didn't have a mouse hooked up so I couldn't get past that screen.
I shut turned it off and back on and I get the death chime again, I've tried about 20 times with no change.
Any thoughts?
