This problem started this week. Not sure if related to my power plug becoming loose and me having to push the plug into the laptop for the battery to charge. Here's my laptop, its a touch screen device with 360 degree screen movement/tablet mode: https/www.acer.com/ac/en/ID/content/model/NX.G7WSN.001
Anyway whenever I wake laptop up from sleep (since its set to turn off display after a while like usual laptops) I get the screen in the first link. The white lines are all over. The small square is the mouse pointer and moves when i move the mouse. Clicking various keyboard buttons cause some obvious reactions but its still white lines all over the display. Problem disappears when I restart and happens again if the screen wakes up from sleep.
1) Reinstalling Intel 520 driver, it says my manufacturer only allows installing their own driver
2) Installing manufacturer driver but mine is already newer
3) Connecting to external display but same white lines are displayed in the external monitor
I'm thinking this is a software issue and not hardware as its totally fine when I restart. Now I keep my screen awake all the time unless I have to go somewhere. Should I reinstall windows? Or try something else?
Thanks in advance.
