XPS M1710, Vista 32 bit SP2 (all windows updates applied), Nvidea GeForce Go 7900GS (latest drivers 179.48)
Upon boot, my screen would come up with large purple squares for a few seconds, then tiny green blocks littering the screen. Before I got to my sign in prompt, the screen would go black, and I couldn’t do anything (even caps lock wouldn’t change). So I booted into Safe mode, and after a bunch of playing around, finally found out that if I disable my video card in the device manager, I could then get to my sign in screen and thus to regular run-mode. But I still have the little green boxes. The odd thing is, they only seem to be located wherever the color of a window/background isn’t uniform. The dots remain stationary on the display, which I can test by moving a border or image around the desktop.
I tried 3 different nvidea drivers (179.48, 175.32, and whatever is auto-installed via regular windows search). I assumed it might have something to do with the ram, so I also ran a few memtest tests and found no errors. If I use an external monitor, the display is still bad (should rule out a defective laptop monitor video wire), and when I do a screen capture, the dots aren’t displayed in the paste (other than the ones that show up whenever there is a non solid color is on the screen). I currently have the display running at 1280x1024 32bit, but if I put the resolution to 800x600, the green boxes get larger.
Running vista repair did nothing, and AVG antivirus found nothing,
Hmm.. ok thanks. I tried using SI Sandra to test the system, but the program won't work in safe mode, and I can't boot into regular mode with the vid card active, so I haven't been able to test the vram properly yet.
