Hi Everyone,

I have been having some difficulties with my PC of late, I'm not to sure why, but the symptoms go as,

Flash of a black screen - At first it was when I closed a video, Netflix or YouTube (Never with gaming though) i would get about a second of a black screen and then back again. Everything else worked fine, sounds etc. However now its doing it randomly about every 1-2 hours.

Keyboard Randomness - This is a new one, my keyboard is working fine, then all of a sudden the keyboard stops working for a period of maybe 5mins then its back, sometimes not, sometimes i need to restart the PC and its fine. I've tried uninstalling the drivers, updating, other keyboards, seems to remain a problem .

They are both driving me crazy, I am a 3D modeler by trade and this is affecting my workflow like crazy.

Just writing this post the keyboard has caused me to reset twice and wait about 20mins.

Any ideas would be super grateful!

Thank you!


My setup is

B450i Motherboard
16GB RAM
RTX 2060 Super

I've used multiple monitors and keyboards and it has happened on each of them

try this step by step (read until end):
  • Disconnect from internet
  • Uninstall gpu driver DDU (clean and do not restart).
  • Uninstall all the processors on device manager (should be 16 on yours, also when it asks for restart, click on no) like this:

  • Restart the pc to bios, and update to the latest bios. Then go to bios again after update and load default or optimized settings.

  • boot up to windows and install the latest AMD Chipset driver...

  • Restart the pc to bios, and update to the latest bios. Then go to bios again after update and load default or optimized settings.

  • boot up to windows and install the latest AMD Chipset driver, reboot, go to power plan and choose amd ryzen balanced, and connect to internet.

  • Install the latest gpu driver.

    *do this all offline until reboot after installing chipset driver, also you may reboot to bios after all of this to set the XMP (and previous settings you did) and make sure ram is on slot 2 and 4 if you use 2 sticks. Download needed files (highlighted word) before doing step 1, do the step by orders.

  • And check windows update (and optional updates) if there is any and install them (except chipset in optional update). Also enable Hardware Accelerated Graphics Scheduling (available on the latest win 10 update) in graphics settings like this and reboot (available on nvidia gpu for now):

Make sure the psu connected to the gpu is 1 pcie cable per 1 slot (use main cable, not the branches/split) like this:
