Hi,
I have the exact same problem.
I have a brand new Acer E1-572G and I updated it from Windows 8 to Windows 8.1
I have read this entire thread.
I note on the Acer website that there are two BIOS files but I do not know which one I should install or should I install both:

In addition, I note that the driver for my adapter (AMD Radeon R7 M265 series) is labelled:
Driver version 13.251.9001.1001 Driver date 4/7/14
I note on the Acer website that the driver they recommend is labelled:
Driver version 13.152.0.0 Driver date 13/10/13
http://us.acer.com/ac/en/US/content/drivers
So my driver is a newer version. Could this be the problem - is my driver too advanced?
If my driver is the problem, how can I uninstall the current driver 13.251.9001.1001 and revert to 13.152.0.0
I would be very grateful for a reply as this is driving me totally mad.
Thank you
