Pull out the PSU and inspect the Q950 board. Make sure there are no burnt traces on the board.
It has onboard Video to connect to a monitor. The Nuvista card was for video processing. Many Q950s ended up in media creation houses but it will run without it. Thing is you need the software and drivers for it. They are great for a lot of things as is, but games, it might be too fast for some games.
The logic board slides out like in the IIcx/ci and LCs - with the front of the machine to you, pull the board towards you and then pull up from the front end. Put it bak together the same way.
I hate Death Chimes. Take all the RAM out of the Q950 and test them on an LC/LCII. If the RAM works, then its the video RAM SIMMs, test that next with the LC/CLCII. I think there is RAM on the board to test it without SIMMs, if not I'm confusing it with the VRAM that is built-in there, just put in 4 SIMMs into "Bank A" to test it (2 on side and 2 on the other). Both RAM and VRAM can give Death Chimes so you have to test what you got. It should be 80ns or faster RAM. I have a video card that gives death chime to any machine I put in it and I have yet to figure out where the problem is.
