Windows 10 Monitor Turns A Solid Color

I am using a Windows 10 Professional 64 bit machine with a NVIDIA EVGA GeForce GTX 570 HD 2560MB graphics card driving a LaCie graphics monitor and a Dell monitor.

I had my computer shop who I highly trust format the C drive and reinstall Windows due to virus and other issues. I did not experience the trouble explained below before Windows was reinstalled.

The day after I picked the machine up from the shop while using the computer both monitors turned to a solid color. The only way to recover was to power down the machine and restart the machine. The machine booted up fine to the desktop. A few hours later the same thing happened again only the monitors turned to a different solid color. These are not the blue screen of death as there is no message on the monitor when it changes to a solid color. This has happened about 6 times since I picked up the computer from the repair shop on September 3rd.

I thought it might be an old video driver that the new Windows install used. I called NVIDIA support and had them email me a link for the latest driver (391.35 - WHQL, released 3-27-2018) which was older than the driver that the new Windows install used. I installed the new driver yesterday and the screen changed to a solid color twice today when I was using the machine - very frustrating as the only way to recover is to power the machine down which is not a good way to shut a machine down.

I have removed the monitor cables twice to check for bad or bent pins and everything looks good.

As I mentioned earlier this problem did not start until the day after the new Windows 10 was reinstalled.

Before I take the machine back to the repair shop I am hoping someone on the forum has some ideas as to why this is happening.

Thanks for your help - Bill

Bro67 thanks for your response. I will try resetting the graphics card but there shouldn’t be any over clocking because i’m using the video card in a normal way with no high-performance adjustments.
