Black screen after windows 10 install.
My laptop Acer Aspire 5750-6831 worked perfectly for about two years with windows 7 64 bit, and after migrating to Windows 10, now presents the following problem:
Only the blue LED of utility power and the fan turn on. Nothing else works even keyboard or mouse - the screen is totaly black. To turn off, I hold the power button for 5 seconds, it shuts down. It is impossible to boot from CD or USB.
I read somewhere that the problem may be caused by incompatibility of bios. It would then be necessary to use a USB stick with a specific software to boot and install an updated bios. It seems that there is a procedure for doing so. Does anyone know how to do this?
