So i have a 2 yo acer laptop and last week i started haveing problems with it : bluescreen all the time shortly after powering it on. I thought that it.s a windows problem so i reformated it but it still has a problem . When i start the laptop sometimes it freezes before the login screen or after login in after a while it starts to freez piece by piece . I mean edge after that the windows bar or any program i have running and i only can see the cursor moving if i do so. And i have to force shutdown the laptop. Or sometimes it just comes up no bootable device. Pls help me.
