    Hello!
    First of all sorry for any errors I make while writing this, English isn't my native language and I'm not 100% sure how all those computer-related words are called in English. Also I'm typing this on my phone.

    I have a rather old PC. Intel i3, AMD Radeon HD7700, etc.

    Never had any issues up until now. Earlier I was playing a game and my screen suddenly turned light blue-ish with very faint vertical lines. Couldn't type anything or click anywhere. Forced a shut down and then tried to restart it. Windows logo appeared, but the screen turned black before I could even log-in. Shut it down again, disconnected it from electricity and tried starting it again. Still no luck.
    (Also: my keyboard "shuts-down" too when the blackscreen appears, my mouse too)

    Tried to look up my problem, and read sth about starting the PC in some kind of "safe-mode". This worked and I could access my desktop again, obviously not in the "normal" quality. Since that wasn't the solution I was looking for, I also found something about deactivating all non-microsoft related programs that automatically start when your PC does. Tried that and I'm back to the blackscreen.

    I'm going to try to find more solutions, but I would appreciate it, if someone could help me, since I'm not very knowledgeable in terms of computer related things. If there's anything else you need to know, I would gladly reply as far as I can. (Also if I find a solution in the meantime, veeeery small chance that its gonna happen, I will post my solution here)

    Thanks a lot for your help!

    Since when all non-MS services are disabled and you get a black screen, then there might be a problem within Windows.

    Open a command prompt right click run as administrator. Then type in 'sfc /scannow' And see if any components are corrupted.

    Try inserting the Windows boot media/installation media USB or a Macrium boot USB to see if the boot continues.
    If it does & you reach the desktop then you can try an in-place upgrade repair.

    Thanks for the replies, sadly I couldn't try any of it today, but I'm going to try again tomorrow.

    "Solutions" I've tried since I've created this post:
    - clean autostart (deactivating all non-microsoft/windows related programs)
    - uninstalling GPU driver (-> worked a little bit, was able to log-in at first but after trying to reinstall the driver it stopped working and also shows a black screen after a while when I start it without a driver.)
    - trying to reset (not reinstall!) windows (-> loaded til 100% and then I got the same black screen)

    Next I wanted to try to follow your advices and if nothing works I'm currently preparing one of those usb windows installer.

    I'm guessing the problem is either a faulty GPU or Windows.

    As you can get into Safe Mode, have you cleaned out the dust & made sure all fans are spinning?

    Just to confirm.
    Did you boot the computer with Lazesoft?
    In other words, you insert the Lazesoft boot disk, boot into the bios & change the boot order to boot from the Lazesoft disk.

    No I haven't tried that yet, since I don't have a free USB-Stick or CD/DVD. Only have the Windows Installer USB.


    Tried that just now, but it says it currently can't run it? It loaded until 100% and then I got a "error"-message

    Ok, that I would make a priority, even if you borrow a disk.
