Hi,

I think I'm having a problem with my graphics card. When I start up, everything is normal until I get to the login screen. red, green, yellow horizontal strips made of vertical bars appear all over the screen, making it very difficult to read anything at all. When rebooting, sometimes my monitor gets "no signal". I openned up the computer and made sure everything was conencted securely. I got the same problem. I re-seated the graphics card, didn't fix it. I had the computer off for the weekend and we had a storm that knocked out the power. But the somputer was off and plugged into a surge protector. Any ideas of what could be wrong or what I should do next? Thanks.

You can try uninstalling your graphics drivers in device manager and then reinstall them. If that does not work your graphics card has probably been fried. I have had lightning strike cloes enough that even a surge protector did not prevent damage to a computer. If you check with the insurance companys only certain surge protectors are good enough to where they will cover computer damage by lightning.

I uninstalled the display drivers and everything seems fine. However, all of the drivers I download also have the green bars. Does it make sense that without the drivers it would work and then with the drivers it wouldn't work? Does that support the idea that it could be fried? I've called NVidia and tried their drivers, including the BETA driver, but none worked. Now I'm contacting Gigabyte.
