I have Windows 7 Home Premium 64-bit, AMD Quad CPU, 8GB RAM, NVIDIA GeForce 9500GT display adaptor, dual monitors (both Planar PL1910M), Qimage Pro v2010.100.
Occasionally the monitors blank out.  Couple of times they stayed off for a few seconds and then came back on.  One time there was a message when it came on about the driver failing and being restored. This last time it did not come back on.  I had to press "Reset" button to restart the computer. A message appeared to "Repair Your Computer".  Startup Repair tests were all completed successfully.
NIVDIA driver is current.
Is there a Win7 version of Qimage?  64-bit version?

I spent 6 weeks getting my system completely usable like you did!

Jack, it is already W7 and 64 bit compliant. V2010-101 sorted out one little W7 problem, we're on 103 now.

Hard to say with any conviction.
After replacing the 9500 withy the 8500 (I am not a gamer person) the machine rand smooth as silk and still is. I have 64 bit W7 in it now and have no video lock ups with W7 either.
That's why I said in the beginning, I don't know if this is a match; meaning whether it will fix your problem or not.
So just keep it in mind, and if all else fails, then change out the 9500 card.

As you say, it is hard for most of us to realize, but the man/company that built my machine went to work to try to locate the problem. He was to run a video diagnostic CD for 24 hours. Yes. 24 yours. It locked up in 14 hours. I asked about the diagnostic disk. It contained a series of very difficult, video intensive game type video switching.
For some reason, that 9500 card broke down. He wanted to try *another* 9500 to see if it was the model of the card or whether it was just that one card.
I already lost the machine for 14 hours testing the 9500, and another 12 hours running the 8500 without incident, and felt I wanted to take the machine home. I could always report back if something went wrong with the 8500 card.
So we never got the answer to that last question.
