Hello guys.

I'm putting a new system together. It's the following:
i7 4770k
Asus Sabertooh Z87
Corsair Vegence 1600mhz 16gb
Corsair AX1200i
Corsair H100i
2 HD's (1 Seagate Barracuca 2T and 1 Samsung 500gb)
Windows 7 Ultimate 64

Everything was working fine, but after a couple hours having the system on in order to install my softwares, the card just crashed.

A lot of green and blue stripes come to the screen. At first I thought the card was running hot (besides I was just installing things and I never started a single game with it yet). I restarted the system and the stripes was there even on the boot screen.

I gave time to the card cool dowh, but it didn't help.

The PC isn't jammed. I'm using it right now. But everything is a mess. I have pixels everywhere. The collors are messed up and there are blue, green and red stripes all around.

I tried to move the card to another PCI-E slot, updating the MOBO bios, but everything is the same.

Is there anything I'm missing or is this a card problem?

Thank you.

Eduardo.

So you have downloaded the latest motherboard drivers and bios from asus website? If so how about the card? Alot of these new cards need bios updates done to the gpu. Check with customer support or on the manufacturer website for a gpu bios update.

you sure have enough power with 1200w hehe. you can run 4way sli with that but back to the subject. I think it is a driver issiue. Try installing one of the old drivers from nvidia and see how it goes.

Sounds like bad memory to me time to RMA!

Another thing it could be is a bad cable connection or bad cable from the GPU to the monitor? You may want to examine and try another cable and or another GPU output.

Is all your settings GPU are at stock values and the 6+8 pin is connected to the PSU?

Thank you. I'm going to try to deal with the drivers today, but the problem happening is before the Windows starts, at the boot and bios screens. Would it still be a graphic card issue?

Yes I do. I will check the card bios updating this evening. However I kinda scared about it. I've never heard about updating the card bios before getting this one!

Well, my card demands 2 cables from the PSU. One 8 and one 6 pins. I have two separeted cables coming from the PSU for each card connection. Both cables are PCI-E cables. Both are 8 pins, but one of them having two pins splited to fit the 6 pins conector.

About the memories and the card/monitor cables, when the problem came along my first guess was the memories indeed. I checked them and they seem ok. I tried to start up my PC with the onboard graphic card and another monitor/cable and it's working normally. Maybe will this test put the memories and the monitor cables safe?

its because my answer was selected as best answer. It sounds like a faulty card. Call the manufacturer and talk to their customer service and just RMA it. Sorry you are having issues but their tech support/customer service might know of a fix as-well.
