GPU Performance Drop?

Hi there,
I have just recently purchased and installed the game Middle-Earth Shadow of Mordor, it was on a deal on the site G2A so i purchased it and installed it. When i first opened the game it crashed and i had to restart. Later when it opened the face of the main character in the menu and the other bits of the main menu were separated into individual pixels, some were purple and some were greeny blue. Then i lowered the graphics to medium and during gameplay the screen started flashing bright green quickly and stopped when it entered gameplay. I was faced with another problem as when it panned out revealing the landscape it froze twice. I lowered the graphics yet again all the way to low, and after a cutscene i looked around and the level was dropping in and out of being rendered. It also happened on CS GO yesterday but stopped and ran brilliantly, so i cannot see it happening on other games.
My Rig is an I5 4670K running at 3.75GHz with 8gb ram an R9 280X with liquid cooling fans 3 TB of storage an SSD and a 650W Corsair VS power supply.
Help would be greatly appreciated as it is a great game and would hate not be able to play it, also i do not want to buy anymore games if it is a recurring problem. Finally i recently cleaned out my computer and it has run much better, i have had problems with crashing before but someone diagnosed it as the fans being clogged up. So overheating is the least likely issue.

Any Help would be greatly appreciated.
Kind Regards,

Let's start discarding possibilities, monitor your CPU and GPU temps with AIDA64 or HWMonitorPro both at idle and load usage.

Test your RAM modules one by one with memtest86+.

Test your GPU with Furmark (at least 30min while monitoring it's temps and usage).

Test your CPU with Prime95 (at least a couple hours while monitoring it's temps and usage).

We'll see what to do next depending on the results obtained.
Also, most likely i think you may have a failing psu capacitor (that psu is a poor quality one with components that can deteriorate quickly), so that's the most likely cause. Try to borrow another psu if you can and see if that solves the issue, if you don't have where to borrow one then do this:

During the first boot, run HWMonitor Pro and enable its log feature, then start your game and sustain it for like 5min during the fps drop, then review the HWMonitor Log, if it's the psu very likely there will be voltage drops either in the CPU vCore or GPU vcore.
