Corsair 600W, purchased 2 years ago.

I have periodic flicker (hard to describe but its an assortment of random colours for just under half a second) when im playing graphic intensive games, and a few times I have had games like Civilization 5, League of Legends and Rocket League crash with the screen having stripes all with the same colour and the audio going from normal to BUZZZ in seconds.

Another problem which makes me believe its the PSU is the fact that my computer refuses to go on sleep mode lately, I put it on sleep mode and 5-10 seconds later is restarts back to the normal screen. If I leave it to idle it shuts down (when I think its automatically meant to go on sleep mode) and reboots when I press my keyboard

I have a feeling its the power supply as my graphics card seems fine and this crashing has sporadically appeared throughout the lifespan of this computer; occuring both on Windows 7 and Windows 10, however it has recently resurfaced and it is quite frustrating as while im thinking of upgrading my GPU my computer is keeping me on edge by these crashes. Corsair has a 7 year warranty afaik and im not sure if this problem is worthy of a warranty swap or not.
 
Ill ask for an RMA number then, I wasnt quite sure if the PSU was the problem. I was surprised as Corsair had a very high reeputation, but I suppose I might have bought a bad model.
 
Volkswagen own both SEAT & Skoda and Bugatti.

Corsair sell the pretty cheap CS and the quite expensive AX series.
