Video Card Problem?

by guitardemon / December 5, 2010 10:51 PM PST

I think I am having a video card problem that I cant seem to figure out and was hoping somebody could help me out. When I start up my machine at the nforce 680I SLI screen there are a bunch of dots all over the screen. They are groups of 2 lines with 4 dots that alternate all over the screen. EX:

.... ....
.... ....
.... ....
.... ....

Then after the computer is fully booted up the screen looks normal except the resolution is different than what is was when everything was working and there are only 4 options for screen resolution size. On top of that i cannot access any of the more advanced settings for my nvidea 8800 gt video card.

Anybody have any ideas how to fix this? I tried reinstalling the latest drivers for my video card, but not dice. Did my video card go bad? Im not sure what to do from here any help would be much appreciated.

that it's easier to test another monitor first or test the monitor on another PC if possible. It may be the video cable going bad.

I tried hooking my monitor up to another computer, and it works flawlessly. Also when I use the internet (on the problem computer) if i scroll down it doesn't scroll smoothly, i guess you would say it kind of scrolls down in clumps.

Did you try to disable the onboard? I assume it's a hybrid sli config you have going. If so, it could be the onboard. Try either the onboard or just the card, one at a time, reconfigure for sli, see what happens.

In reply to: How?

If you don't know how, then you didn't try the hybrid sli. Did you take out the card, make sure there is no dust plugging the card, make sure PCIE slot is clear, re-seat the card, boot up, see how that goes.

Unfortunately, it's beginning to sound like the card itself but we'll see.

From here I can only suggest trying another card or trying THAT card in another PC to be sure but I'm fairly sure it's bad at this point.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
