Q: I just bought a new 19" AOC monitor yesterday, It worked fine all day yesterday until today, where, it won't show the screen although the computer is on. It my be that the computer may have simply overheated, or the video card may be shot, but how come the computer was working fine yesterday ? Would you possibly think this was the work of a virus ? Or do I just need to let my computer relax ?
A: The first thing to try if you have another computer that you can use, will be to connect your new monitor into someone else's computer. If it does not work then you need to take it back and get it replaced. If it works there is a problem on your computer. You will need to get your video card checked, but if you do not have any expertise, just take it to store where you bought the monitor and ask them what is wrong.
