Software constantly crashing

What type of video card do you have and how much memory does it have?

What type of video card do you have and how much memory does it have?

I have a AMD Radeon™ HD 8690A 2GB GDDR5.

So I installed the software onto another computer and again made it through the calibration but then the program crashes again. I can choose the type of scan I want to do, accept the settings, but when I click scan I get the "time remaining 120 seconds" message, but the progress bar does not move and after about ten seconds the program crashes. It seems to me that it is putting a call to the scanner head for something and not getting anything in return, which is causing the hangup. Could it be that my scanner is a lemon? Just has something wrong with it? Could you please let me know if there is a workaround?

If the software crashes before you can close after calibration, I'm not sure the calibration has properly been saved and applied.

I have no evidence yet but stability issues and Radeon cards may be related. ALL of my stability issues were traced back to my video card. I spent many hours diagnosing this so I hope you can benefit from this expended effort.

I am now using an Asus GTX 670 Direct CuII 4GB now and I think it is likely the best board for scanning you can find for the price. This scanner is heavy on graphic memory primarily.

Can you scan in free mode?

I ended up wiping my computer and doing a clean install of Windows 10. I will attempt to install and run the software again tomorrow. I wasn't able to scan in free mode or with the turntable. My computer has two graphics cards, and I am able to dedicate programs to the secondary card (didn't know that was a thing), so I will try that and let you know how it works out. Thank you for the info on the Radeon cards. You never know with these things.
