Downloaded and read your Memory Dump.
Do you have the latest BIOS installed for your Motherboard. FM2A68M-HD+
Try installing the AMD ALL in ONE Driver (I believe it also includes the CHIPSET Drivers) from Asrock for the new CPU: ASRock > FM2A68M-HD+
Strange that it works in a linux environment but not in Windows. You should reset your Motherboard BIOS back to "Default" by removing the CMOS battery according to your Motherboard's manual. Make sure you don't have anything Overclocked which might cause BSODs.
When you upgraded the CPU did you upgrade any other hardware like RAM Memory or Hard Drive?
In AMD Download page I don't see a specific AMD Driver for the A8-7680 with R7. So I would download the AMD Driver from the Motherboard which should be compatible with the new APU.
See if the Motherboard's Graphics driver works or not.
Hello, sorry for the rather emotional description of the situation.
Thank you for your answer and your suggestions.
I have the latest BIOS (5.10), because only it supports APU A8-7680 and the second dual core new APU. I updated this latest BIOS just after it was released that year. So far, I had an A4-6320 on board and replaced it with the A8-7680. Nothing else has changed. In UEFI, only the memory clock is set fixed according to their capabilities (similar to the A4-6320). With the A4-6320 both Windows and Linux worked properly. The only difference that appeared in UEFI after mounting the A8 is fTPM (this module works quite capriciously, so I reset UEFI to default settings by resetting from its own level).
After installing motherboard's graphics driver (so it also contains drivers for the southern bridge, PSP, USB, etc.) and restart = BSOD, one more restart OK, another: BSOD, etc.
If Windows starts correctly, everything is stable, even in challenging games. In Linux, the same games running with Steam Play work correctly. Loading Linux with video encoding and graphical benchmark = everything is stable.
I thought this is a BOX processor and will be supported like any AMD product with GCN. However, after your suggestion, it looks like this is more OEM and drivers are on the motherboard manufacturer's website (but do not work properly 
).
I suppose Linux can handle all this probably because amdgpu supports all graphics cards, both mobile and desktop, without any special optimization. And this APU is a quite untypical connection because it has GCN 1.2, Excavator cores and ... DDR3 instead of 4.
My system is based on BeQuiet! Power System 7 400W. The computer includes: Asrock motherboard, which we have already talked about, 2x 4GB GoodRam 1866 MHz Dual Channel, CPU we are talking about, 2x DVD-RW, SSD + HDD. That's all.
The temperature measured on the heatpipe (by thermometer) right next to the CPU in stress does not exceed 40 degrees Celsius. CPU cooling is Cryorig M9A + thermoconductive paste with silver powder.
The error appears most likely when loading the graphics driver, because during one of the Radeon driver installations, just after trying to reload the new graphics driver, BlueScreen occurred.
I have 3 additional drives, so I installed new, clean installations on them: Windows 10 1803 x64, Windows 7 SP1 x64 and Vista x64.
Vista works without any problems, because there is no Radeon driver for R7 (from what I searched for) and runs on the standard driver.
Similarly Windows 7, until the installation of the Radeon driver. After installation, an error message is displayed each time until I uninstall the graphics card drivers in safe mode.
Windows 10 as the only one has built-in, working drivers for my network card, which causes that already during the last stage of installation there was an error as in the attached picture (I suspect that he tried to download drivers from the network, although I haven't met with something like that yet on 10). After installing Radeon drivers, every second restart/start is an error.
I attach a picture of the screen with an error we are talking about.
Thank you very much for your help.
As I wrote earlier on clean, newly installed Windows 10 and 7, without anything, after installing the graphics card drivers from the Windows Update machine, the above mentioned error appears. The computer has changed only the CPU from A4-6320 to A8-7680. I have a different motherboard but A88X, which is not compatible with A8-7680.
I created a new AMD SERVICE REQUEST according to your suggestion.
Additional information after the two OCCT tests:
All graphs in the attachments.
Sorry for the late reply. While running the CPU and PSU stress test, did your computer crash by any chance?
OCCT is showing GPU running quite hot:
I imagine it is referring to the APUs integrated GPU. Most likely a misread by OCCT.
If you said you made a clean Windows installation and as soon as the APU driver starts to load it BSODs.
At another Forum that specializes in BSODs, one of the Windows expert mentioned that if you made a clean installation of Windows and it BSODs that generally indicates hardware problem or failure. Since there are no 3rd party programs installed or drivers except the APU driver, in your case.
Could be incompatible RAM Memory in conflict with the new APU. If your RAM Memory is not compatible with the new APU, it could cause BSODs to occur or your computer not to boot up. I noticed that your RAM is not listed in your motherboard's QVL list: ASRock > FM2A68M-HD+ .
In fact I see only one RAM Memory of 1866 Mhz Speed in the QVL List:
Try using only one RAM Stick on the primary RAM MEMORY Slot and see if it BSODs.
The QVL list is a list that the manufacturer tested the hardware for compatibility and other issues. If it is listed it means that hardware (RAM for instance) is fully compatible with the motherboard and BIOS.
If it is not listed it could mean two possibilities:
1) The hardware was tested and found not to be compatible
2) The hardware hasn't been tested yet for compatibility issues and thus is not listed.
So your RAM Memory would fall into one of the above categories.
Hello,
when it comes to answers:
0. When Windows already running with installed graphics card drivers, there was never a crash. Even during the OCCT test.
1. The CPU has been accepted for warranty claim. I sent the processor to AMD, and so far I re-installed the A4-6320, which works 100% correctly. There is one difference, the controller of this A4 supports memory only up to 1600. However, the same memory used to work with the A10-7800 processor at 1866 clock and there were no problems.
2. As far as RAM compatibility is concerned, in my opinion it has no idea at all. RAM chips meet certain standards at 1866 clock, and the processor itself has a controller that supports them. These are not overclocked memories or, as in the case of new designs, OC versions. I think that memory was not tested by Asrock, because it is a Polish manufacturer, perhaps not very popular outside of Poland.
3. As far as temperatures are concerned, in the case of APUs (and I already had 3 different APUs: A10-7800, A4-6320 and A8-7680) I do not trust what I see, I measure temperature manually. Here is an example:
