Graphics Cards

[walti]

Hi guys, I'm facing a continuous problem with my current setup:

• AMD Graphics Card
  • 8192MB ATI Radeon RX 580 Series (XFX Pine Group): 
• Desktop or Laptop System
• • Desktop
• Operating System
  • Windows 10 64bit
• Driver version installed
  • Radeon Software Edition Adrenalin 2019 19.4.3
• Display Devices
  • HP Standard monitor 1920x1200
• Motherboard + Bios Revision
  • Asus PRIME B450-PLUS (AM4)
• CPU/APU
  • AMD Ryzen 7 2700
• Power Supply Unit  Make, Model & Wattage
  • Cooler Master 850W
• RAM
  • 32 GB Corsair DDR4-2132 (1066 MHz) CMK32GX4M2B3000C15

I've changed my old Sapphire R7 240 4GB video card with a newer XFX RX580. Since then I have had a lot of problems whenever I use any proglam that works with GPU: e.g. Adobe PS/LR, VLC viewing videos, even a browser like Chrome or Firefox when there is some page with embedded videos. My PC starts to show random errors regarding memory access, disk corruption and so on, until ilt crashes with a BSOD (normally with CRITICAL_PROCESS_DIED error).

Also, all diagnostic/benchmarking programs like (but not only) GPU caps viewer does the same disaster... I can replicate the situation all times

In any case, before crash I'm no longer to launch any program, nor ctl-alt-del works, neither shudown completes.

What i did: 

- swapped video card with another one (identical) - no good

- completely reinstalled Windows 10 from scratch - no good

- removed AMD drivers in safe mode: the problem arises also without AMD drivers, just in case... - still no good

Other than swap the card with another one that does not use AMD drivers, there is anything else I can do? Any ideas will be appreciate a lot.

Thanks in advance!
