Ok so I've been determined to try and troubleshoot this one myself for the past week and it has gotten me nowhere so far. Let me bring everybody up to speed on what has happened. I have a DV9535nr HP Pavillion, specs are in signature, that has an Nvidia 8600M GS display adapter that has stopped working recently and I cant seem to keep it when I shut the laptop off. The other day I opened the laptop lid and it said "Resuming Windows" like normal, and then bamm, everything went to VGAsave on the screen. 640x480 4 bit colors, etc. Just crappy. Naturally I turned it off went to F8 on startup and Last Known Good Config. Booted up ok I figured everything was fine. And I had been getting the all too nortorious screen flicker and blank for about 12 seconds then "display adapter has stopped responding and has recovered" message since day one. But this time the screen went black and the laptop just hanged. So I had to turn it off and back to the 4 bit color crap. SO... read through a bazillion forums on laptopvideo2go.com got a lot of good ideas but none of them have really stuck thus far. Did the whole Driver Cleaner deal with safe mode to remove step-by-step any trace of the drivers. And re-installed them, rebooted. Initially this method worked fine. But when I got to any sort of screen flicker deal...back to square one, and I'd have to do the process all over again. We'll like 3 days ago this stopped working all together. Tried registy cleaner, CCleaner, Drive Sweeper. Nothing. So sometimes I could get the drivers, seemingly anyways to stick but when the adapter stopped responding that was it. And in the device manager it shows Code 43 Windows stopped this device because it reported errors. Not Code 19, cannot load the drivers for this device because it's items in the registry are corrupt, or w/e it goes. I've even tried the newer nForcewares an such with a modified .INF to see if that would fix it. Finally, I backed up everything on my first HDD to my second and reinstalled windows thinking it was a bigger problem than that. At first again, I was able to install the original drivers from HP's website and then when I shut it off, it came back, like it forgot what I did??? And that is where I'm at. If anyone can offer any suggestions other than Buy A New Card it would be greatly appreciated.
