Flickering Lines

My old GForce GT9600 512 MB was doing fine. Everything was fine, and no flickering lines on screen. Though, the other socket (left side) has an issue, and there were flickering lines, but I don't plug it. Oh, I am using DVI monitor, and the brand is AOC.

I wanted to buy something newer and faster one. So I bought PALIT GT440 1GB GDDR5. But there's a problem:

-Flickering lines on screen annoy the heck out of me.
-In deviantART, flickering lines appear browsing at dA's homepage, gallery folders, and some pages.
-In Google Chrome, by clicking the "new tab." Flickering lines appear again. (I'm using Pinkie Pie theme. Hey, are you a brony too?)
-Sometimes, flickering lines appear everywhere.
-I think, flickering lines will appear on some websites or maybe more. (And I don't like it).
-all of above, it went black screen for 0.5-2 seconds. And sometimes it went faster to get black screen like 0.5-1 seconds.

Unlike, the GForce GT9600 has the same sockets (Both are DVI but different functions. Left socket has an issue, and the right socket does not). While the newer one I bought has an issue, though it got DVI, VGA, and HDMI. And I don't even have a VGA adaptor.

How do I get rid of these annoying lines on my screen? I don't want black screen and it won't let me see their pictures! Do I need to get a better adaptor, or VGA adaptor, or something?

So please, oh please, reply me back, and tell me what to do!

You might want to check you're not overloading your power supply.

I don't think this will help. I've never overloaded my power supply not even once. It's everything fine on my GForce GT9600 but not GT440. I've downloaded the latest version of Nvidia Graphic driver, but there is still a problem, except GForce GT9600.

Okay, before installing that driver. Do I have to uninstall Graphic Driver too? Because I am afraid to do it, it might blacken my screen, and can't see what I am going to do.

When you install NVIDIA's later drivers such as the 270 and 275, they give you the option of a clean install, which will delete the old driver first.

Can I do it in Safe Mode?

Also, I don't have a PSU Label. I think someone lost it. Not me, because I just bought and used it.

Oh, I did the clean install though, but flickering lines are still there.

I think you really do need to get your power supply checked out. If you're not sure what its voltage/current/wattage parameters should be, check it out on Google.
