Hello, everyone. Well, I am in real strife. I am asking for help as a last resort because I just can't solve my problem alone. My problem started a couple of days ago, and I cannot use my computer at all in normal start-up mode. The error that is reported in the event viewer is in the title of this thread. The description accompanying the error message follows: The following boot start or system-start driver(s) failed to load: AmdK8 AvgLdx86 AvgMfx86 Fips In addition I am getting a blue screen STOP error 0x000000EA when I reboot normally. It reports that the problem file is nv4_disp. I should add that I had this exact same problem a year or two ago. The solution at that time was as simple as changing some setting (or perhaps a single registry value - I can't remember). I found that solution on the Internet somewhere, and I have spent around 12 hours trying to find wherever I found it last time. My point in saying this is that, on that occasion, there was nothing wrong with my video card/display adapter (NVIDIA GeForce 8500 GT) as many of the threads on the Internet regarding this problem suggest. Can anyone please help?
