Connected it via hdmi but can't get it to switch the display to it using the function keys. It was while connecting it up via hdmi that the laptop screen actually worked for the first time and it took a bit more testing to realise it was just to do with moving the laptop rather than the external connection lol.

You might be right about it being another component as I pressed the mouse button on the touchpad a bit harder than I had done previously as a click hadn't registered and the same thing happened. Looks like i'll have to take it all apart to have a look but got a feeling thee won't be anything visible. Guessing this could be caused the motherboard having a small crack somewhere, from maybe being dropped or something and pressure or a small flex of the board is enough to cause the problem?

I had already tried reseating the memory so it's not that.
