Before I start, I doubt it's my moniter going out since it runs EVERYTHING else perfectly fine with no blue lines. It's mainly paint.net especially with the text. To start off I have had these very annoying blue lines on my computer. It really demonstrates itself when I'm using paint.net hovering over the text. (see the photo) It blurs out what I want to see until I scroll down, and it completely disappears when I scroll down too, unless I hover over the text again, then it will start the blue lines. I have a feeling it's a setting somewhere probably in the graphics card or BIOS, but I really don't know... Also this happens on a few other things, for example when I'm installing something and it shows the installation wizard if I hover over the blue bar on top it will act up unless I move the actual installation wizard around. Here's a picture to show you what's going on in paint.net View attachment 245 So if you can see it right, I pointed arrows at the blue lines, it's very weird how it works. The blue lines are also flickering a lot kinda like the refresh rate is messed up, yet I read that the refresh rate doesn't not affect LCD's which I have. If it matters I'm running on Windows XP Service pack 3. It has been bugging me for awhile now and I'm wondering if anyone knows a fix or has had a similar problem.
