DescreteVideo Card Slow-down

[XSainth]

HI! I'm currently trying to get a solution for a problem with my HP 15-db0091ur laptop.

Laptop specs: 

AMD Ryzen 3 2200U 2500 MHz/15.6"/1366x768/8GB/1000GB HDD/no-DVD/AMD Radeon 530/Wi-Fi/Bluetooth/Windows 10 Home

As you can see, there is a hybrid system of AMD Radeon Vega 3 and Radeon 530.  About two with a half months ago a very unpleasant problem appeared. In some applications (games mostly), which use R 530 card as a main GPU, a strange thing happens: the total perfomance of the card drops to very low values on absolute random basis (WIN 10 task manager shows that it falls from 80-100% usage to 15-20), and so the FPS drops. And after a week or two after appearance of that perfomance-drops, happend my first BSOD.

Figured out (found people in the NEt with similiar problems) that the GPU automatically overcloking for better perfomance, but have serious problems with swiching back to normal (From 3D compute to 2D especially. Its enough to just Alt-Tab to desktop to get a BSOD), which results in BSOD's with "Thread stuck in device driver" with problems in "atikmdag.sys" and "dxgkrnl.sys".

Tried to reinstall Video driver, installing older/newer versions, updated BIOS - no result so far. Asked for assistance in service centre in shop where i bought it - the took it to specialised HP service-centre, but no result. Spend a month of waiting and no results at the end.

The solution for now, which prevents my laptop from dying after exiting the games: installed "Clock-Bloker" and set all the rules for "Downclock". But still have that low-perfomance appearance problem so far. Checked a temperature in TechPowerUp GPU-Z, but everything seems normal: temp is the same in the normal and low-perfomance situations (1-2 degrees differnce, its floating after all).

Would be really glad if enyone had met this problem and found a solution!
