My monitor was shutting down every time I would click a link on my browser. The monitor would shut down, but it's power light would remain on.
When I push the power button on the monitor and then press it again to turn it back on, my browser is there with the link that I clicked opened.
It seems to be working now, but I'm afraid it might start doing it again.
By the way, the electric in my house shut down and then came back on while my PC was on right before this happened.
