(Sorry for not the best english, but it isn't my first language) A few days ago my pc start giving me some blue screens with some errors that that says something about memory management and stuff. I looked on the internet and find out that my hdd might be the problem. I took a program that allows me to check my hdd life and it said that it isn't in such a good shape, so I bought a new one, but the problem now is with windows 10, I can't go to any shop because most of them are close now with corona virus thing going on, so I downloaded windows 10 from their website and make u bootable USB drive and all, I start installing it, making the disk partitions, everything is fine, it finished. I got the same error a few times, so I tried to install all drivers with their updates for video card etc. (I read that the bad drivers can give you blue screens too) , when my windows shut down without giving any sign of bluescreen or something, restarting and then giving me the lockscreen, putting my password in, but after unlocking, everything was black, couldn't make anything on windows anymore. I installed the windows two more times, because the second time i installed it, the windows just installed over the first one, and finally when i finish with the third time installing the windows 10, everything seems fine, until it stoped again for no reason, but this time any of the windows functions didn't want to work, I could see my desktop, but start menu, notification menu, anything from windows didn't want to work. I tried entering in settings, I only could do that trought "personalize desktop" thing because nothing else work. When I opened the settings, task bar didn't show me any icon for setting and when i wanted to see what's going on, the program was named with @sistem and much more words after it. In the end my windows 10 went all black again and now I really don't know what to do. If someone will stay and read everything and can help me, all I can say is thank you.
