Hey guys,

I'm having an issue with my PC at the moment, and am unsure of what component/thing could be causing this issue.

Basically, there are some horizontal lines which flicker on my 2 screens (yep, both of them); they are very quick and stay for a split second, before flashing somewhere else a few seconds later. Sometimes, a big chunk of the screen gets cut off quickly, and it is really distracting!

If it is any help I have noticed a few patterns, it only happens a couple of hours into the computer being turned on, and seems to start when I am watching a YouTube video (although I could be wrong).

My hardware if it helps:

AMD FX 8320
RADEON R9 390 - Might be this causing the issue.
8Gb's of Kingston DDR3 Ram. - Might be this causing the issue.
ASUS M5A97 LE R2.0 mobo - Might be this causing the issue.
Corsair 750w bronze PSU
Zalman Case
1tb wd SHDD

One of my RAM slots is dead, so i'm wondering if another is on the way out!

Any help is appreciated! Even just a suggestion :p !

Cheers
