    I am having issues with my PC at the moment; just last week my dual monitors went black and kept displaying the "No signal" message, meaning I had to force restart my computer (hold down the power button) in order to do anything. After this restart, my PC got to the login screen, and after typing my password and the fade-to-black that displays my desktop, my screen stayed black and never displayed it. After 10 minutes of it being black, I had to force restart my computer AGAIN to continue.
    This is when the problems occured, the computer went straight to startup repair, and after selecting the available options to repair my PC, they would all fail until there were no options left. I decided to take my computer to a Pc repair shop, and after "fixing" it, they told me it was most probably a software issue from something I downloaded or a windows update, so they had reinstalled windows. I turned on my PC and everything was normal, and after reinstalling some of my programs that I was using it was still fine.
    Today however, I was browsing youtube and my monitors both go black again, both displaying the "No signal" message.
    I have tried re-plugging the DVI and HDMI cables, but the same message is still displayed.

    Does anyone have any suggestions on how to fix this? I don't want to take my computer back for another repair as I fear the same will happen, and the fix cost a lot of money for just a reinstall. I have posted the issue here as my best guess is that it is a video card problem, but I do not want to buy a new one to find out it wasn't the issue.

    It does sound like a graphics card issue - as you are running twin monitors I would assume that you have a plug in graphics card with both monitors plugged into it as opposed to an onboard chip (System Details as noted by retiredlearner are important otherwise there is a lot of guess work involved :))

    First I would unplug and reseat the graphics card and, if it has a separate power lead ensure that it is well connected (remove & replace). Test

    Then I would run with each monitor singly and see if the issue remains. If you have an onboard graphics chip - highly likely - test out with a single monitor using the motherboard connection. If there is no problem with this arrangement then the graphics card is a likely culprit.
