Hello guys. I have a PC with Gigabyte ga-f2a55m-s1 motherboard. I tried out a video card(quadro 5000) and now I'm facing problems. So i put in the new card and I installed a driver for it downloaded from nvidia site. After that started the problems. I've got black screen without any response from my PC. After that I replaced the quadro card with my GTX 650 that I used before without any problem. The windows started up and I thought that everything is alright. I removed the quadro driver components in windows and then restarted my PC. The black screen and freeze showed up again.I thought that it's a problem with RAM connection or something like this. So I checked it, put out and back in. Now my pc started and I went to the BIOS. 4GB RAM was recognised and my another RAM stick wasn't.(I had 8GB). So I checked it again, after that I've got black screen again. After around 20x tries my PC finally started with 8GB RAM. But I've got the blue screen error in Windows. Then I decided to reinstall my windows and formatting my drives. The installing started but the blue screen error apparead again. Now I have no idea what is causing the problem. I tried to run with just one RAM stick but still got errors or freeze at startup. I also updated my BIOS to the newest version but still nothing. CMOS battery was also removed.I would really appreciate your help.
