So i decided to fire up my brothers computer that he hasnt used for about 2 years and keep running into the bsod with the error about nvlddmkm.sys for my graphics card, the monitor is also blurred as in the colors are distorted and random colors will blurr to the right or the left of where they should be. I can get it to bootup once i go into safe mode and delete the nvlddmkm.sys but when i try and install the latest driver and reboot the same problem and same error pops up. Any advice on how to fix this error? And I was hoping that by installing the newest driver properly that perhaps the blurry screen will clear up, is that just wishfull thinking or could the blurry screen actually be fixed? The computer is running vista 64 with 4g ram and 750w psu. Thanks for the help guys.
