I have a Sony VAIO SVE15136CN, with Windows 10(x64) installed. I recently formatted it. It worked fine for a few minutes, but crashed on restart. I checked my Hard Drive and recovery media, but they had no errors. I was unable to pin down the error. I formatted the laptop several times, but to no avail. Then I went step-by-step, installing the drivers manually as per the SONY website, not via Windows Update. That was when I figured out there was a problem with my Display driver (AMD Radeon HD 7500/7600M Series). Each time I installed it and restarted, my PC crashed. Even after I installed the drivers, some Windows updates were needed, so subsequently I let Windows Update run to install them. This installed the AMD Display driver also, and my PC crashed while finishing updates on restart.

So I used Windows Disk and Recovery Tools(DART), and via Disk Management, in the Drivers section, I disabled 'amdkmdap' and another similar driver which I can't recall. This has worked so far, but I get the error 'AMD drivers not installed' from AMD Install Manager on every startup. This allows me to use the PC, but unfortunately I cannot adjust brightness.

I used the 'automatically detect driver' and also manually selecting the driver and installing(amd-catalyst-15.7.1-win10-64bit), but to no avail. This is the latest driver. Display driver still keeps crashing.

Can anyone suggest what I should do, so that I can get the 'adjust the brightness' setting back? Maybe a link from where I can download older official drivers of my AMD graphic card?

    Have you used a previous version of the driver to verify the problem is with any AMD display driver or just the current AMD display driver? – Ramhound Sep 10 '17 at 20:33
  • Yes, I had used two other versions - one from the official Sony website for Windows 8(Original drivers for Windows 10 aren't provided), and other from driverscape.com(a 2014 driver). Neither worked. – user635883 Sep 12 '17 at 8:27
