Hello I've got a biiiiig problem with my graphics or something... The problem is that my screen goes black, starts to flimmer alot, that all the pixels in my screen just switch to a random color and I often get blue screens... Sometimes I get a little warning sign that says the picture screen driver "nvlddmkm" has stopped working and has been reset. I tried reinstalling my graphics card several times, both with the drivers from the CD I got when buying the graphics card, and the drivers that I downloaded from the creators homepage. I also tried switching my graphics card to a new one this week but the same problem appears. Please help me, I have no idea what to do!
