I've seen a few topics about this, but none of those "solutions" helped me. I'll start with the beginning. Been using Win7 for a few months now and the first month was great. The somewhere in october I was suddenly getting flashes in the lower part of my screen. Since then I've been sending and resending my laptop back to Acer. They replaced all of the screen hardware yet I still get these flashes. I've also tried every driver out there. When using Aero I get the flashes a lot but they don't go away if I disable Aero. I'm getting really desperate as I've been without my laptop for 2 months now. System specs: Acer Aspire 5920G 2 Duo Processor T7500 NVIDIA GeForce 9500M GS TurboCache 4GB DDR It usually happens when I run a program, it flashes more often when using heavier programs or games. Kind regards!
