i have also noticed that the screens flicker between each open programme and don't respond to commands straight away, have to click like 5 times

The first thing I would do is run SFC /SCANNOW Command - System File Checker

Then get your OS and drivers up to date. You're way behind on Windows' updates.

I've already tried the scannow command and i thought it had fixed things but 2 days later back comes the BSOD problems.
