NVIDIA Geforce 9800 GT problems (screen flashing, pixels, etc)

Hi, I recently got a new power supply and a graphics card (NVIDIA Geforce 9800 512 mb GT) installed into my computer. Previously all I had was a ATI radeon 3200 onboard chipset for graphics.

Upon turning it on for the first time, things seemed okay, but graphicsl glitches and errors have happened nearly everywhere. Here is a list of some of them-

-If I drag my mouse over desktop icons or any buttons, sometimes a larger image of that area will appear next to it.

-If I click and drag a desktop icon, sometimes a rectangular area will glitch out, such as a portion of my desktop picture growing larger as it passes over it.

-When I scroll through an internet page, at random frequent intervals the area it is scrolling through will grow huge, though it isn't reall there as I can't interact with any of the larger buttons. When this happens the scroll bar disappears. This happens alot and is even happening as I type this post. Portions of this text are randomly popping up in random spots on my screen, at a large size, as if I was on a small screen resolution.

-When trying to play World of Warcraft, my fps is higher but it just is not rendering 3D anything well. Shapes will flash with color, sometimes the screen will just go black and random glitchy graphical shapes of different colors will appear and flash, making the game unplayable. The enlarging problem happens in game too. If i have the options menu open in World of Warcraft, there will be a huge options menu just above it, large in size but unclickable.

And ohers...

My info-

OS- Windows 7 Home Premium 64 bit
Processor- AMD Phenom(tm) 9650 Quad-Core Processor 2.3 GHz
Installed Memory- 8.00 GB
Graphic Card- NVIDIA Geforce 9800 GT (512 MB, one DVI and one VGA port)
Graphic Card Driver Version- 8.17.12.6099
Monitor- HP w2338h wide LCD monitor, VGA port
750 watt power supply
Directx 11 (Which is a bit of a problem since this card apparently doesn't work well with it, and World of Warcraft usually only needs Directx 9 and/or 10.)

I'll try to print-screen some pictures of what exactly the graphicsl glitches are looking like, though half the time they simply don't appear in the picture at all. A lot of times dead or flashing pixels will appear all over the screen, whether its on the desktop, in an internet window or in world of warcraft, and they get worse if I scroll up or down, but they never seem to appear in a screenshot via print-screen.

Main graphic problems-

-Lots of pixels flashing all over, sometimes around the edges of windows as well.
- Random portions of the screen grow huge or a second larger version of the area flashes over near the original real area, whether it be in WoW, an internet window or the desktop, usually after scrolling, clicking or mousing over something though sometimes by doing nothing.
-Youtube videos randomly growing larger and larger versions of them flashing over the youtube box.
-World of Warcraft 3D rendering problems, making it unplayable.

The only screenshots that actually work are the in-game World of Warcraft ones. Here are some that show some of the graphical glitches.

Looks like a dying graphic card... Do you have a spare? If you do, test the spare, see if the problem persists...

actually if he goes into the bios he might have to disable the onboard that may be the conflict the onboard is on when it should be disabled

Hi.

I have that same card, it's an EVGA one. You can also download Rivatuner, so that you can make sure that your card is being cooled properly and you can set a manual speed for your card to be cooled. Also get Speedfan, too. That way you can monitor your temperatures. PC Wizard works too.

Riva tuner is awesome i used to for my 7300gt

There's already too many apps for that already It would end up being a version of cpu-z with options
