So, not an antique by any means, but being an i5 is what made me suspect that it may be an AVX2 issue. Recreate the problem then open Windows Event Viewer and seem if an error was logged under Application or System messages It's an i5-3570, but running Windows 10 64-bit. If there is a job running look for and review the log

What stage of operations does the error occur? Is there an encode running?
