Graphical issues gaming

[ollien1997]

Hi I have been experiencing problems with my PC graphics for the past year, It is so frustrating and I still have found no solution.

When I got the computer, games such as Red Orchestra 2, Chivalry and Rome total war 2 ran absolutely perfectly, until, fo whatever reason I start to experience issues with the graphics, which appear on all games.
When moving a get vibrating or shimmering lines on objects such as trees. I also find that the grpahics reduce quality at distances. Another issue is that objects 'pop' into the screen (draw distance issues).

Here are some examples from another PC but are very similar to my issues.

Here is my specs

Intel Core i5-4570 3.2GHz Quad-Core Processor

Asus H87-PLUS ATX LGA1150 Motherboard

Corsair Vengeance 8GB (2 x 4GB) DDR3-1600 Memory

Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive
£40.00 Buy

Sapphire Radeon R9 270X 2GB Tri-X Toxic Video Card

Zalman Z3 Plus ATX Mid Tower Case

XFX 550W 80+ Bronze Certified ATX Power Supply

Samsung SH-224DB/BEBE DVD/CD Writer

Microsoft Windows 7 Home Premium SP1 OEM (64-bit)

The effects are reduced when I decrease the anti-aliasing, on the games, however it still persists just less obviously (this is 100% not 'just how the games work' as the issue is obvious I can compare the games with my brother who has a worse spec, and although my PC runs the games with better FPS etc, my PC has these noticeable grpahical issues.

I have had this problem for a while and have tried everything I can think of including:

Updating all drivers,
Using different grpahics cards
reinstalling windows
Changing screens, plugs, wires,
Checking power supply (all fine)

Thankyou for any information/help it is very much appreciated and I cannot thank you enough!

You changed video cards and the video corruption still happened?

 

[ollien1997]

yes, several times. Changed monitors also, HDMI leads and DVI. Sharpness on monitor and resolution.

Well, in a situation like this, you have to look at what has NOT changed. And in this case, that would be the motherboard, memory and the power supply.

Give me the brand name, the model number and the capacity (power supply) that you are using.

XFX 550W 80+ Bronze Certified ATX Power Supply. <-- Is this what you mean?
I have checked the memory using memtest and all was fine.

What about the motherboard and memory? Brand and models pls... I cannot see your system. I need you to paint me a picture of what you have.
