Hi everyone! Now here is my problem: first of all I checked as many "black screen of death" threads as I could during these past few days. There seems to be many different versions and solutions for this but none of them worked for me so here I am. Now when I start my laptop, everything goes fine until the welcome screen (have win 7 btw) The welcome screen appears at a lower resolution (1400x1050) while my normal resolution is 1920x1080. After the welcome screen, I see my desktop for like 0.1 seconds (at 1400x1050 again) and then everything goes black. Only ctrl-alt-del works but nothing there works too so I cannot see the task manager if I open it too. This happens 80% of the time I turn on my computer (or I just go to sleep mode and when awakened, most of the time I dont get the black screen) I tried startup repair, reinstalling display drivers, malwarebytes, and some other fix I found on the net, but nothing. Then something came to my mind. Now when at home I always have a HDMI cable connected to my external monitor so I don't use my laptop's monitor. And the resolution I use on the external monitor is 1600x1050. Now I am away from home for a while and this black screen started when I am away (and using the laptop monitor ofc) So I thought maybe this has something to do with this, what do you think? And I am also open for other suggestions too Also sorry for the loong post but I appreciate your help, this is so annoying.
