I have this problem since last night and there had no problem from I bought my computer last year until last night. I leave my pc there and I went out somewhere. When I get back, I saw my screen blank, and no responding at all. I force shutdown and restart again, the bios screen didn't show up. But after a while I turn on my pc, I can see the bios screen again and log on to windows. After that I go to event viewer and check what is that error just now, and the error message is: "The description for Event ID 14 from source nvlddmkm cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer." And then I didn't bother that and start to play game. But suddenly my screen went to look like low graphic, many pink pixed, and then went to blank screen. I force to turn off the pc and then turn on again. I searched all over the internet and they asked to uninstall the driver and reinstall again. But still have this kind of problem, even I surfing internet the problem still occurs. I really no idea how to solve it. Is there anyone have this problem also? Does have any solutions for this?
