About 10 days ago I started to get a random screen flicker or blackout when using MPC-HC. It's super short, but very noticeable - and annoying! I have done everything - restored from a month old Macrium backup, updated codecs, Media Player Classic, NVidia drivers, Intel drivers (Dell 7746 has two video adapters), but the flicker continues and only when using MPC. I've looked in event logs but there's nothing related to MPC. Can anyone offer any suggestions to troubleshoot this problem?
