Hello. First time post, please be gentle.

I have a graphics card problem; I'll probably try my best to explain the problem and hope someone or anyone can help me find a solution.

At any time I have a game that requires the use of OpenGL, I seem to get these random white flickering of graphics randomly on Icons, Backgrounds, Text, or anything that is an image. Here are some images to such problems if it helps.

Warcraft3; Notice the background is white, and it reguarly flickers to white and back to normal. So do those icons with text on them.

World Of Warcraft; All the icons and some graphics are flickering in this picture.

World Of Warcraft; Same picture, just not when it's exceesively flickering. This is what I would hope it stays like...

The flickering are sporadic and yet very frequent, with 3 or 5 seconds interval. Happens in *every* game I own. I've asked a lot of people, and friends; the most they give me are a tilted head then say, your eyes must hurt.

I am using;
P4 Intel(R)
Celeron(R) CPU 2.80GHz
1GB of RAM
Windows XP (Service Pack 2)
DirectX 9.0c
19" Flat Panel LCD hs94p Sony

nVidia GeForce FX 5700LE
128MB PCI CARD (sorry no AGP slot!)
ForceWare Version 71.89

Things that I have done are;
Updated Driver
Uninstalled Old driver
Cleaned Registry
Tried older versions of nVidia Drivers
Tried different PCI slots
Kicked the computer
Examined the Video card if fan is broken, it's not.
Insulted it, and apologized to it.
Searched Google for almost a week.
Stuck a HUGE fan next to the computer
Latest DirectX installed
Adjusted Frame Rate for games to match desktop's framerate.
E-mailed nVidia, they said to update driver...
Exchanged the video card. Same problem.

Integrated card doesn't seem to have the problem, but this video card does. I either have a double bad luck on fluked video cards or there is something wrong on my half, which I am hoping to find out. Apparently this is the best PCI card I can possibly get without having to upgrade my motherboard for an AGP slot, so I hope I find some sort of solution.

Any help or suggestions (except buy a new computer) are welcomed!
