Black Lines Appear in Browser Window When Scrolling - November 1, 2010
I recently brought a 10 year old XP Pro machine back from the dead with a new motherboard/cpu/memory. Everything was working except in both Firefox and Internet Explorer the act of scrolling caused massive screen redraw problems and black horizontal lines to appear in the browser window. Also, the scroll bars would be out of position and sometimes 2 scroll bars would draw although only 1 would work. I thought this was a video driver problem, but it wasn’t!
This problem was fixed by disabling the dual core cpu so it would only use a single core. In the system bios this was turned off by choosing Advanced->cpu configuration->unleashing mode->disabled. This system uses an Asus M4A77TD with an AMD Sempron 140 2.7GHz and DDR3 1066 PC3 8500 RAM.
