Hi i had just recently changed my thermal paste and since the laptop has been acting weird as it starter getting stuck at welcome screen and stuff now suddenly the laptop is showing dancing pixels like in the pictures i have posted below. it doesn't occur while booting but as soon as it reaches the moment to show a welcome screen it shows a black screen and some green dots and all of a sudden it show the screen with filled pixels. Im in doubt as it is a hardware problem or a software. the laptop turn on but stucks when tired to open start menu, so i can get access to safe mode and i tried using a hdmi to check a external monitor but the results are same which makes me more nervous and scared as i doubt its a huge hardware problem
I have a battery that requires a replacement , but i fixed the startup freeze by disabling fast startup and as i was changing the thermal paste the servicing guy had not unscrewed a screw and tried while pulling the lower cover and the screw was the one attached with the mother board i heard a squeak does it mean the motherboard has taken some damage ? but it worked just fine after servicing all the temps were balanced.
