Mine is a black screen problem. After doing the removal of everything, pressing power button many times it starts but shows boot device not found, then I need to change the bios settings and other things. I also found in one test that there is error of partition table. PC is working, but the same problem again and again is time consuming. What can I do? Now the system is not starting. this is quite frustrating as I can't blog. I started relying temporarily on online work in covid times, this issue is frustrating me a lot. Dell laptop keeps giving issues. I have tried to list down my problems completely. Few times it started but now it is not starting even after trying numerous things. I will be thankful if dell helps me.
