Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:

You might want to try and reinstall your GPU drivers manually after you've used DDU. It could be a driver issue but you've been very vague with what you have to work with.
