Guys, need help. I have a flashed MSI Radeon 6950 Twin Frozr II (not OC), and it worked well for at least 1 year, but suddenly crashed, causing black screen after windows loading every time I turned on my pc. I deleted all drivers with Driver Sweeper and this solved the black screen problem, but it appeared every time I tried to install drivers (the installing process was always finishing with warnings). GPU-Z showed me some strange numbers - 768 shaders, gpu clock 150 and 250 memory. So, I decided to reflash it and that's it - now it won't pass POST, no beeps from computer, nothing at all, just black screen. Tried flashing with 2 cards and different bioses, still no progress. If anyone knows what can cause the problem or how to solve it, I will really appreciate your help. Thanks.
