I just got my laptop (Acer Aspire TimelineU M5) back from getting its inverter repaired and its motherboard replaced (not sure why they did that part, just troubleshooting I guess). Now, when I use it I am getting flickering artifacts (black bars, faded images of other parts of the screen, etc) whenever the GPU (an NVidia Geforce 640M) is running. I've tried replacing the drivers, and so far that hasn't worked out. The only things that seem to stop the artifacts are safe mode and disabling the GPU entirely.
Acer will take the unit for rerepair, but as their repair center is in a different city, I'd just love for somebody to tell me that this is a software issue which I can fix myself.
Thanks.
Sounds like a failing GPU to me. Probably a hardware issue.

Yeah, that's what I thought... Guess I'll have to ship it out for the third time. I won't be getting another Acer, that's for sure.

Wait, WTF? Reset the computer to factory settings, and no more flickering. It looks like it's a software issue after all... But if it's not the drivers, then what could it be? Or maybe I'm not resetting the drivers properly?
Try using driver sweeper to get rid of drivers when you're uninstalling them
