NavadeHi

Thank you for the confirmation, I've sent an email to the shop where I got the GPU from, but I still didn't get a response, so I guess I'm waiting... :p

I also ran the Windows RAM check and there were no problems found. Now the 1GB bar is removed and I still get the artefacts, I didn't get them with the 2GB bar out, so now I'm going to test if it's the slot, because there were no problems found and I didn't get them with my previous GPU...

Aw, I just saw some artefacts and now I have installed the latest drivers from ATI, not Asus.

I'm pretty sure it's not my monitor, because I can make a printscreen of it. I took out one 2GB bar from my setup (7GB: 2x2 and 2+1) and the artefacts seemed to disappear, because when I inserted it again, the artefacts came back. But I also tried removing the 1GB bar and I haven't seen any artefacts until now, so it seems the problem is that I have 7GB RAM, does anybody know about this? (Maybe a fix or something? It's probably the graphics card, because I didn't have artefacts with this same system and an other GPU) OS: Windows 7 x64 (Ultimate) | GPU: Asus EAH5770 Edit: And I had the problems since I replaced my GPU.

Yeah, it is a printscreen. I have an Asus EAH5770 and do you mean my normal RAM? Should I use Memtest86 in order to test it?

Hi, I joined this forum because I have a problem with my PC (artefacts) and I was disappointed by other forums because they couldn't provide a solution, so I tried to find a more elite forum :p

Hello, I'm having trouble with pink/green stripes trough my screen, I got my graphics card tested and it's fine, it's neither my power supply nor ventilation. Here is a screen, I hope someone has experience with something like this: http://extremetechsupport.com/forum/attachment.php?attachmentid=736&stc=1&d=1267642613 I should also notice that I use Windows 7 x64 - Ultimate and that my PC is not infected. (The artefacts are not always visible) Thank you in advance.
