Graphics Card See's Spots and Flickers Wile in Games

Hi, Let me tell you about my GFX Card,

its a 128MB G-Force 4 Ti 4200, the graphics card it self is an amazing Card, had it 3+yrs now, bought it at its Prime on the high end scale.

over the past yr, its been showing its age, like last yr, it was Summer, and very hot, the GFXC Fan Protective Casing, Melted and warped into a Cone Shape.

so here are symptoms..

White/Blue/Orange Large and Small Dots, sometimes they flicker like a xmas tree, sometimes they only flicker when I move.

Large Segments of Walls Flicker, Dots are shown though the walls, Floors Show flickering Pattens.

Sometimes hole Segments of Walls Disapear showing whats behide the wall.

Reason for the sudden change,

I cleaned out my PC, everything is now dust free, Wile I was fixint some stuff, I put my driver on the top of graphics card and what am thinkin is the top just mashed with the sudden connections to diffrent areas of the card.

I smelt something and then I felt the card, only 1 part of the card was burning so hot I couldn't touchy, I paniced and turned off my PC, the part that was hot was.. if you placed the card in the machine, it would be flat, its was the right, outside part near the hard drive.

normally, nothing else would get hot, only the core.

My Fan Doesn't Really Spin around anymore, I got 2 open the case and give it a nudge with the driver.

I had a major Heat Problem, sys=38c cpu=57c, so cleaned everything, took me 5+hrs, and reorganized it for better Air physics, I'd cut out parts of the Casing, Added New Fan Places, the pc now looks like the day I bought it, with the consideration of the new Look.

now the temp is sys=29c cpu=48c

the cpu is a amd PC2400 clocked at 2.0ghz

think I've given enough info.


anyone know how I could fix this problem? I've installed the new gfxc update for this card, I really don't want to go out and by a new card when this card is still perfect without the dots and flickers.
 
any advice?
