Hello everyone, Recently my mom gave me a laptop which is an Acer Aspire 5570z and it came with Windows Vista Home Premium 32 bit. its an older computer but she didn't want it! and well... I did. I noticed the screen brightness flickers a lot and its annoying and also inter fears with my game (maple story) I don't know if it ever flickered on Vista since I only had vista for about.. 30 seconds. Why does the brightness flicker? and what can I do to fix it? -Thanks!
