Finally got around to fixing it!
-Pulled it all apart
-Took the case off
-Took the small PCB off
-Undone the 30 odd screws and took the keys off. (didnt bother cleaning the keys too much work)
-Peeled the green circuit thingy off the metal plate
-Scrubbed the metal plate, It had some sort of gunk on it!
-Gently wipped the green thing on both side with just warm water, Could see an obvious buildup of gunk, got that off!
-Let it all dry,
-Put it back together,
-Plugged it in today and seems to be working fine!!!
Thanks to Iggy_Drougge and koaftder for your help!!
