MSI R9 270x installation troubles

[Grimezy]

I just built my new rig last night and am having issues with the graphics card. My setup is basically:

Case: Aerocool Dead Silence
Mobo: Asus H81m-plus Micro-atx
CPU: i5-4440
Ram: Corsair vengeance LP 8gb
GPU: MSI R9 270x
PSU: Corsair RM550
Windows 7

When I first booted the PC I was worried to see strange white stripes all over the screen, this was in bios, startup screens and on windows. The stripes range from chequered boxes all over to big thick ones all down the screen. I installed mobo drivers as normal and then headed over to AMD to download the latest drivers; it prompts me to restart my pc to finish the installation and now all of a sudden it won't boot up into windows. I kept having to uninstall the drivers in safe mode and then it would work again (display still showing stripes).

I checked all the connections and they seemed fine APART from one of the PSU connections to the GPU. One of the 6-pins would click in nice and easily, the other one required quite a bit of force and despite appearing fully in, would not click. This still did not fix my problem.

I decided to remove the GPU and boot from the integrated graphics which is now working perfectly so it clearly must be something to do with the GPU. I'm currently installing anti-virus, etc but I really want to get this issue fixed ASAP. I'm going to re-install the graphics card and triple-check all the connections but I wanted advice on whether I'm missing anything or if there's something I can do to help? There is a switch on top of the GPU which I'm not sure what it does, would this have any significance? And I'm right in thinking I just need the GPU connected to the PCI-E slot with the 2 6-pin connections and that should be it? I'm not missing anything? (the user guide was pants!)

Any help would be much appreciated, this is my first build and so far everything has been a bit of a pain, I was hoping the GPU would be the easy part....

Thanks in advance!

check to see your running the latest motherboard bios and update it,then try the gpu

the switch on the gpu is probably the bios switch,it has a main and backup bios

Thanks for the advice, I've updated the bios and reinstalled the GPU making sure both connections clicked and that it was properly seated in the PCIe slot. I'm still having no luck though... Screen instantly goes back to a messed up state and as soon as I install the AMD drivers it won't boot into Windows.

Does it sound like a faulty GPU or is there anything else I can try? :\

I've attached some pictures if it helps:











Thanks again

is that through hdmi? do you have dvi/vga ports aswell just to see if it does it on those

tried disabling the igpu in the bios?

does seemlike a faulty gpu tho

Urg I've had that on a gainward and either the gpu or vram was faulty!

Tried on DVI and HDMI with no luck Tried disabling the iGPU as well.

I rang OCUK and they told me I'd have to speak to MSI who aren't open on weekends so I'll have to see what they say tomorrow. I've been using it with integrated graphics and it's ok for things like GW2 but obviously isn't that pretty.

I'm local to the OCUK store next weekend and was thinking of popping in, do you know if I can return items there? I also bought a CPU heatsink that was too big for my build which they're RMA'ing but if I'm nearby I may as well drop it in rather than post it.
