Screen crashing when idle ?

Try turning the monitor on and off then moving your mouse, or disabling monitor sleep mode altogether and just turning your monitor off yourself. It's a driver bug i believe that is under investigation
my RAM is playing up atm aswell

You obviously know a lot more than me about AMD drivers Matt but is this still a problem from ages ago or is this a new thing? I had this issue with my launch 7970s IIRC. Something to do with idle clocks
I had this problem once. I thought it was just a windows setting issue and kept meaning to get round to troubleshooting it. I would just reset whenever the screen stopped responding until one day it wouldn't respond at all. Turned out to be the GFX card on it's way out, and inevitably it failed. I got it replaced under warranty and the problem has never reoccurred since.
Of course it could be something else in your case, but if you do have a spare GFX card, or on-board GFX you could test then it might help rule this out now.

Don't know mate, does not affect me on my 290's. It does happen sometimes on my second rig though which uses a 7770, i just disabled monitor sleep which is no problem for me.

If it's the sleep bug (card failing to come out of sleep) then it's existed since about as far back as 2010 and there are still complaints today about it. If it's just crashing at idle not during sleep then it could be a number of things, driver bug like LtMatt says or faulty card (unstable card at idle voltage).
