After using my 6870 with the AC L2 Plus for around three months, last night while gaming suddenly (without ANY whatsoever previous symptoms) my PC froze and the screen got corrupted with blueish and greyish squares. I did reset the PC and it got no video signal anymore, so I change the DVI cable for an HDMI cable and it works.

Now comes the strange part: If the drivers are installed, is crashes and freezes my PC when it loads the desktop, the only way to use my PC is to not have my GPU drivers installed (what I'm doing right now).

I've tried the following: Installing the GPU on all of my PCE-I slots and fresh Windows 7 install. Both failed.

The temps of the card were 30-40c on idle and 70-80c on gaming load with high ambient temps (30c normally). Also it had a 60mm fan on the VRMs heatsink.

Any ways to find a way around this so I can use my GPU with the drivers for basic usage until I can buy a new one?

After I install the drivers and I reboot, immediately after the "welcome" when it loads the desktop i get the display corruption (horizontal purple lines) and my PC freezes/crashes.
The card is not factory OC'ed.

Hi there,

First I would uninstall current drivers in safe mode, install the drivers from the website of the vendor.(don't download the latest version but maybe the one before that, so you're sure that it's not an auto-update that caused this).

if it doesn't help continue:

Did you check if the fan-ways are clean ? mostly troubles with GPU start with overheating !
If there is dust inside then clean it out !

If you overheated the GPU it could be that some connections came loose from its motherboard.
In this case you need to heat the video-card in a specific way. (but that's a worst case scenario).

Let us know,
Cheers, Louise.
