I have a the following problem with my laptop. Suddenly, one morning I went to start it and when it gets to the logon screen, the screen just shows random horizontal lines, totally indecipherable. But I can still log in, and shut it down, by just using key combinations, I assumed it was a hardware problem, but wait... ... I can still see the BIOS screen fine, I can still get to recovery mode, that is also fine. I even can boot into a recovery USB (Hirens), screen still totally fine. So I assume now it is not a hardware problem now but windows. I tried with an external monitor, no change.
Tried rolling back windows to earlier version, but only managed to uninstall last "quality update" no joy. Then I tried to reset windows, twice, both times, screen works fine, but then at some point during install it just prints the weird lines on the screen again. I tried removing one ram stick at a time, either way I still get the same problem when I restart.
Other info:
- the screen garbage looks like the horizontal lines are out of sync, I can see the mouse moving, but it spread out in tiny lines all over the screen.
- Normally I actually only get black screen, the only way to see the garbage is to plug in the external monitor cable, otherwise the laptop screen stays black. Nothing ever shows on the external.
- Acer aspire E 15 (E 571 32nu)
Next things I am going to try are: installing ubuntu or similar, if that works then I will stick with that, really I only need this laptop for Teams, VPN and remote desktop. OR Maybe the windows reset was the wrong method, and it is just reinstalling the same broken/incompatible drivers. Could someone point me in the direction of a how-to, that lets me install earlier version of windows (without losing my licence).
