APU : AMD A4 3300 with HD6480G
GPU: AMD HD6750M
OS: Windows 10.0.166299.547
(Yes, it's an old Laptop but for me it's enough)
What happened before;
-I overclocked the GPU a few months ago.
-I started getting a message saying that HardDisk is in trouble.
-Windows has corrupted itself during an update. But it continued to work even though some applications did not open anymore.
-I can no longer do any Windows updates due to this corruption.
What happened during:
I was working on a DirectX 11 application and suddenly the screen froze. I waited a little bit to see if it was working again and since it did not come back, I held the power off button and restarted it.
-When I rebooted, BSOD showed up.
What I have now;
-The laptop has become completely useless.
I uninstalled the drivers, because versions 14.9, 15.2, 15.3 did not work and every time I install the drivers the BSOD appears. The latest version available for my APU is 15.2 and for GPU it is 15.3.
-I needed to reduce the CPU clock, because when the GPU is uninstalled it keeps running to the maximum making the laptop overheat.
-I can not use any DirectX application which is the only thing I need before buying another computer.
I have found no way to make dedicated and integrated GPUs work independently. The two need to be working, otherwise Windows uses the "Basic Display Driver".
What I tried to do;
-I tried installing several versions of the driver. BSOD in all cases. The drivers were downloaded on Windows Update and AMD page.
-At all times I used DDU to uninstall the drivers.
-I tried the "expand.exe atikmdag.sy_ atikmdag.sys" thing. Windows doesn't recognized the drivers.
-I tried to reset the Windows. It did not work because of corrupted system files.
-I tried to restore windows. It did not work and I do not know why.
What I want to know;
-If this is a driver corruption problem, is there anything I have not tried yet?
-If this is a hardware problem, how can I identify which part was damaged?
-The GPU continues to "work" when it is uninstalled making the computer warm up. This is a good sign?
-If the problem is in the GPU integrated to the APU, how can I use only the dedicated GPU?
-If the problem is with the dedicated GPU, can you use only the graphics of the APU?
What I need now;
- That a DirectX application will work until I buy a new PC.
What I can not do;
-Lose all files stored on HardDisk.
