A few weeks ago, I had my desktop's 250gb SSD hard drive replaced with a 1 TB SSD drive. I leave my computer on all the time but close all the apps and monitors overnight and have set its power settings so that it never shuts down or sleeps. Recently, when I turned on the monitors some mornings, I found that Windows has closed but the computer light and monitors are on and see a message saying there is a problem and offering a choice of restarting the computer, which I have done. Today, I got no message, the computer light was on, the monitors' message was that they couldn't connect and I had to restart the computer with its button. I ran scannow a couple of days ago and it found no problems. How can I fix this problem? Thanks.
