I've had this issue since the rollout of nvidias newer software suites 44x.xx
Uninstall your current driver.
Go into Nvidias advanced driver search and download 436.02 ensure you select the correct "Windows driver type" DCH worked for the latest win10 updates.
Install and good luck. Has worked for me for the last 6 months.
I'm running RTX2080 | i7 5820K | AsRock Fatal1ty X99X Killer | 16gb corsair vengeance 2200hz
