Hey guys. Lately I've been having this problem with my monitor (or Graphics card, not quite sure at this point) in which there are flashing black bars going across the screen, and I could really use some help. The problem persists usually about every other day, but it has never been quite as bad as this before. Attached and at the bottom of this post is a screenshot of the monitor with the black bars.

I've noticed that this happens more frequently when I play games such as Team Fortress 2 on Steam. The black bars would actually usually start at that point, and I would even find blue pixels laying in spots across the screen at some times. After playing for about an hour the game/screen would either start flickering or a message will pop-up stating, "Input Signal out of range".

I have a second monitor that doesn't have this problem at all, and this all started after I had returned from vacation in Mexico.

Steps I've taken
-Reinstalled and Reverted to old NVIDIA drivers
-Checked for new monitor drivers
-Checked monitor resolution and attempted using the monitor at a refresh rate of 59Hz/s
-Checked and unplugged/replugged monitor cables.

Also, a note: While in some programs (such as Firefox, Office, or Chrome) the black bars seem to have stopped. But going back to the desktop and they're still flashing.

Thanks in advance for any help.

Try connecting that monitor to another known working computer. If the problem persist, bad monitor.
If the problem stops, resolution may be set to high on original computer.
