I just got a new computer from Dell this week and I am having issues already.
On my screen I get little boxes after having the internet up, or a picture or anything. The boxes are pink, green, purple, etc. See the picture below.
I have installed new drivers, uninstalled them, updated them, etc. Then I called Dell support and they did they same thing. When that didn't work they told me to do a full system restore- that didn't work either.
The video card is a nvidia 8600gt and I downloaded the drivers from website as of yesterday. I have also tried multiple DVI cables.
I read that bad memory elsewhere can cause issues like this or that it is strictly video card issue.
Any help? Dell said I might have to send it back to them and I want to avoid doing that if I can.
That looks like a video card artifact. If you see them in the desktop like that, it's usually means 2D clocks are unstable. Since you probably didn't OC your vidcard, I'm guessing that the card itself can't handle the speeds.
One way to test if this is indeed the problem is to get a OCing tool, such as Rivatuner and ATI tools. Learn how to use them, and then down clock the 2D clock speeds and see if the problem goes away. If it does, the vidcard is defective.
Well Dell inhome tech came today only with a new motherboard. Sweet... If I would have known he would have come so soon with the Mboard, I would have told Dell to send the Vid card at the same time. Of course he changed out the motherboard and what a surprise, we still have the same problem. Hopefully the Video card will be here monday or tuesday.
I received 2 new video cards yesterday. Thankfully I got 2 because one of the replacements looked beat. Anyway, I installed the better looking card and updated the drivers from NVIDIA's website. So far everything seems to be going well, for now. Thanks everyone for your help, your knowledge is invaluable.
