I have had a problem with my laptop for a while now and have only just been able to capture the issue on video. The problem started many months ago, perhaps the start of 2015. Bascially the screen flickers very badly and sometimes across the whole screen but it only happens when the main body of colour displayed is black. As you can see in the video, the second I press the windows buttton the flickering disappears. This is why I have been unsure whether or not it was my laptop hardware or software. I would appreciate it if someone knew how to fix this.

To me it appears like the graphics memory of the page areas are changing with content and shouldn't.
- 1st suspect is incompatible graphics driver
- BIOS issue
Why OS was on this before. Not details on whether this is a clean install of Win 8.1 or factory image (but I doubt it is as it sounds like an older machine).

Also, these are the things that I have tried so far.
-Wiped computer completed and started from scratch
-Updated all drivers and software
The problem also doesn't always appear. Sometimes I can use it for weeks without it ever showing. Up until I made this post it hadn't done it in 2 months and now its really bad.

It could be failing memory. Windows 8.1 safe boot has memory diagnostics. Run it also if you have two SODIMS swap them and see if the problem changes (crashes a lot etc) or go to One SODIMM at a time.
It could also be heat related. Graphics chip over heating. Have you cleaned you ventilation system from dust build up (It can plug up the channel)

It what the memory boards are called in notebooks!!! SODIMMS
Anyway, you would have 2-4GB or 1-8GB SODIMM My reference to swapping them only works if there are two modules. Shared graphics memory uses your systems RAM that is why I indicated that. Only if you have descreter graphic such as NVIDIA will there be addition dedicated memory on the motherboard but also likely Optimus controling it.
