So as being said, my computer have been acting up lately, it crashes randomly, in game or watching a youtube video and the screen just blacks out and displays the message "Div no signal" there is still sound but its a constant loop of that one track like "boo boo boo boo" sound. Its been happening for many times and its getting annoying. After it crashes, the only way seems to "fix" it is by taking out and ram and plugin it back in again, after that it works. After the computer boots in to windows, the brightness and display setting resets, that mean the screen is really bright and is not like how I have set it before. So I need a solution to this because its have way too often.
