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

If we based our suggestions on your two sentences alone, we'd be running around in circles. Please also mention all that you've tried to rule out a bad PSU or a faulty GPU. TO me it looks like you either changed your display or you got a GPU upgrade.

How many threads do you need to open to garner solutions?

Which slots did you populate the rams in? How are you connected to your monitor? Speaking of which what is the make and model of your monitor?
