Ok, in the past few weeks my graphics card (Geforce 7900) has been having some crazy issues. Lil dots on the screen, during games there are major problems like lines, tearing of graphics, sometimes the desktop screen will flash on and off. Now I bought a new PSU cablet o connect to the card thining this will fix it, but it didn't. Its still worse than ever. I put in the old graphics card that came with computer, and all problems went away. However its a fairly low end card, and Id rather fix the problem. What could be causing this? It's not overheating because this does this happens right away. I'm open to any ideas.

The physical dimensions of dell PSU are different from standard power supplies, so a general PSU will not fit inside the dell case.
Why do you want to change your PSU?

It sounds like your PSU is putting out enough for the video card. When you upgraded the card did you upgrade the PSU? What is the max wattage and +12V amperage on the PSU (usually written on the side of the PSU)?

The PSU suggested above would be a good alternative to the one you have now. It won't however power a card much more power then the one you currently hold, the sole reason why your paying a premium for the PSU is because dell PSU dimension aren't standard so there is a smaller market for them, rendering higher production costs.

If I got one of these http://www.newegg.co...N82E16812189003
and connected the vid card so it has 2 cords to the PSU would that make it run better?

No that connector splits one molex connector into two. To power your graphics card you need a 6pin PCIe connector.
