I just bought a GeForce 9800 gt to replace my old card and am having some "ghost imaging" on my screen. The same thing happened the last time I got my previous card so I rolled back my drivers and it fixed the problem. For some reason, this time it won't work. I've rolled back the 5 previous drivers and the problem remains. Any ideas? Here are some screen shots so you know what it looks like.
I don't see how that can make small boxes appear on my screen. From what I understand, Clear Type is enabled.
Sorry about that, I had not let the images load when I posted. Those "boxes" look like the artefacts you would get if the VRAM is on it's way out but it could be that your 350w PSU is starting to fail.
