My system caught a trojan about 3 or 4 days ago. I've had so much trouble with... well... every type of harmful data in existance, that I didn't even bother to try and remove all however many thousands of infections the trojan had instantly downloaded. In any case, one virus got in, it disabled my anti-virus, disabled all my security measures, and disabled my firewall. So... transfered all the files I wanted to keep to a portable HDD, then reformatted the infected HDD.
Fast-fowarding to a short while ago... installed Windows XP Professional. Installed Norton System Works. Installed nVidia GeForce BFG 7800 GT OC drivers, installed nForce 4 AMD series drivers. Restarted to finalize all that. At the "Welcome" screen, the screen goes black for a moment, less than a second, then continues as normal. All's fine then. Every time I click on the nVidia icon in the task bar, the screen goes black for a moment, then returns to normal and the menu pops up. If I click "NVIDIA Control Panel", the screen goes black for a moment once again, then returns. Sometimes the NVIDIA Control Panel pops up, sometimes not. I go online and download the absolute latest compatible drivers for both the nForce 4 AMD Series and GeForce BFG 7800 GT OC Video Card. No difference. Even tried downloading the latest update for the nTune program, just in case, for the hell of it.
I thought this might be due to Norton. Reinstalled Windows XP Professional, followed all the same above minus Norton. Same issue.
So... maybe it's Windows XP Professional? Installed Windows XP Home Edition, followed all the same above minus Norton. Same issue once again.
I have an SLI system. I installed the OS with both video cards installed, but the system doesn't even notice the second video card anyways, never did since the day I bought it, so it acts like it's not there, makes me doubt that that could be causing the issue. I'll post another thread regarding that issue as well...
Summary: Temporary black screen appears for less than a second everytime an NVIDIA graphics-related program is interacted with.
EDIT: I'm thinking this is a driver or OS related issue, not a hardware issue, thus I posted this thread in the Windows XP Home and Professional section.
