First, remove any newly installed programs which could be causing issues. Also make sure to have the latest motherboard and hardware drivers installed, especially updated graphics drivers. (Check for those drivers at the computer manufacturer or device manufacturer's website.)
Next, run "chkdsk /f /r /x" from an elevated command line which should fix any damaged files and file space.
Once that's done, if the problem continues, then it's probably time to perform a clean install of the operating system, all drivers and all programs.
Hope this helps.

I have installed a 2TB into an existing system that does have Windows 10. The problem that I am having and was having prior to the new hard drive, the monitor would give these two messages: Monitor going to sleep and Push Button Lock-on. I have tried multiple times of starting the computer. I have held the power button in for 30 seconds per the recommendations. I have tried two other monitors and get those same error messages. Called Staples to see if they could help but they wanted to charge me $169.99 just for a diagnostic. I know there has to be an easy fix for this, but I am not able to find it. The reason for the new 2TB hard drive was b/c prior to Hurricane Florence, my computer was giving me the blue screen of death so I wanted to upload a new hard drive in hopes to fix two things but it seems as though nothing is working. Please help me on this. It would greatly be appreciated.
