Hey, everyone. I'm back with another problem. This time, it's in my personal laptop. So, about 3 weeks ago, a friend of mine installed 4 GB RAM into my laptop. After a couple of days with the RAM, I turned on my laptop and find my screen flashing red. Parts of the screen were pixeled red. After backing up my files through safe mode, I brought the computer to the college tech support. They figured it's a driver problem, so they updated my video driver. Into what, I cannot remember. The problem randomly appeared, and that forced me to format and start fresh. So, a new problem arose. As the title suggested, I randomly get the nv4_disp infinite loop BSOD. Sometimes, my screen would just freeze and not do anything. Sometimes, the screen flashes but I can still move my mouse pointer. And it hasn't really been too friendly when I open the only two games I have in my computer in an attempt to see how bad the damage is. I looked up some solutions online, which included uninstalling and reinstalling drivers. After a few attempts of that with the 186.81 update the NVIDIA website provided, I rolled back my driver into driver version 22.214.171.124. So, here are some things about my computer: Model: Dell Latitude D830 System: Microsoft Windows XP Professional Service Pack 3 Computer: Intel(R) Core(TM)2 Duo CPU t7500 @ 2.20GHz 2.19 GHz with 3.5 GB of RAM Driver Details: Currently NVIDIA Quadro NVS 140M Driver Version 126.96.36.199 Personally, I wouldn't mind this problem. But I have a final project for a class where I need a video presentation and I am using Pinnacle Studio 10. I'm not sure if it's just me being retarded and missing a driver to install, but I'm pretty sure I reinstalled everything after formatting my computer. Any help is greatly appreciated. If any more information is needed, please tell me so I can attempt to provide you with correct information (not completely tech savvy for a computer engineering major, ironically).
