TwistedI had similar issues but without the video input issues.
Although my problems were related to a faulty ssd.
Use CrystalDiskInfo to detect possible problems (bad sectors for example), it's a pretty small and user friendly program, if it says your storage drive is in good condition, then you don't need to worry about that, otherwise at risk will tell you there's something wrong with it, and below you find the source of your problem.
