Hello! I recently upgraded to windows 10 because I was kind of careless with my pc that previously had windows 7. Since I was reformatting my system I thought I might as well upgrade it as well. Everything was really easy to set up compared to windows 7, everything seemed great. That is until I get a message on my screen displaying "DVI NO SIGNAL" (May not be those exact words but it conveys the same message). When this occurs I cannot come back from sleep mode, even when pressing my keyboard and mouse attempting to wake it back up, forcing me to restart my computer. There are rare occurrences where it tells me something is wrong with my windows 10 and pops up with an error followed by a disk check on restart. But in the end nothing fixes it and it keeps forcing my computer to go to sleep randomly despite there being activity from even the mouse itself. I've heard this a common conflict many people have who possess a nvidia graphics card which is most likely the cause in my case. I've never had any issues like this with windows 7. I've tried everything from changing the power settings on sleep mode to never, checking if the keyboard and mouse are set to wake up the computer when it enters sleep mode, to cleaning my PC of any dust; focusing mainly on the graphics card, and downloading older nvidia drivers as well. I've read so many online articles and none of them seemed to have worked. This happens a lot when I'm running a game, such as CSGO, but can happen when I'm just browsing the internet. Downloading old nvidia drivers made this happen less frequently but it still happens making it extremely frustrating. If you have any ideas all help is appreciated!
