Question 2 GPU's 2 Monitors one Driver, Yesterday it worked.

[skulledave]

So,
I got a Nvidia GeForce GTX 1660 Ti and a Nvidia GeForce GT 520 in my Asus Mainboard.
The 1660Ti is connected with a HDMI to my MSi 144Hz Monitor.
The GT520 is connected with a VGA to my old HP Monitor.

Yesterday i installed the newest Driver for my 1660Ti and Ta-Da, the MSi Monitor was primarly set up to my 1660ti as the Main Monitor and HP Monitor was running with a wonder as my second.

But, Today i restarted my PC like everyday and nothing. Just my MSi with the 1660Ti is working, tried to reinstall Drivers for both GPU's, dis/-enabled in the Devicemgr,

I really dont know what to do, any ideas? Thanks.

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition? Heavy use for gaming, video editing, or crypto-mining?

Disk drive(s): make, model, capacity, how full?

Swap in known working video cables or change video ports between PC, GPUs, and monitors. Start with the VGA connection to the old HP monitor.

Individually test GPU's and monitor combinations to determine if one particular GPU or monitor is the culprit.

Be methodical and change only one thing at a time.
