HELP! Getting random white or pink patches

[Ali Altaf]

Help! my Graphic card is having weird problem. In every game i am noticing several patches in every game in different way...
in GTA IV several white polygon,small box flickering in buildings when moving camera. with ICE Enhancer 3.0 these flickering are even worse.. (i am getting solid 29.3 fps because i set Vsync to standard 1/2 refresh rate and fps limited to 29 in Nvidia Inspector advanced settings) In ICE Enhancer 3.0 MOD i am getting pinkish stars type blocky minecraft like patches flickering around my screen.

in Amazing Spiderman same can be seen as small pinkish box
in Just Cause flickering weird grass type pattern flickering up-scaled fitted to screen when movie forward on the mountain
in Max Payne I can see flickering patches which are very far but looks like that door texture is corrupted.
in Need for speed can't noticed any such flickering because of it's blurry game-play.

These white patches are so annoying i mean this spoils all fun of gaming

I have tested Furmark and can't notice any error or weird thing happening. and used Video Memory Test Stress v1.6 but this software also got no errors. So where is the problem? if there is no flickering in Furmark and VMT test passed then why why i am getting flickering in all the games

Please Suggest me a better VGA testing software to pinpoint the error. because Furmark and VMT failed. No BSOD just weird annoying flickering.

and Yes! My PC had beep beep beep issues.. I mean Intel Beep code (beep beep beep) was playing and PC was not starting up but when i blow dust in my PC casing and i removed my Graphic card and put it back and it's working again but i am getting weird flickering in games... however no flickering in Windows 8.1 desktop, only getting flickering in 3D games!!!

Sound like artifacting. Only way to get rid of that is to get a new card. Were you statically grounded when you removed the card via a wrist strap ground?

Noo... I just opened cased blow dust inside entire casing and then i removed gfx card and put it back. not used anti-static wrist strap. when i did these all things my PC was off with power cable removed from PSU! and yeah this is actually artificating with glitches like small polygon, triangle shape or small box like patches in buildings mostly.. these white or any other color patches are not many in numbers therefore game is playable and i can ignore this patches... however playing with ICE enhancer is horrible, too many patches although i get 27+fps with v-sync 1/2 refresh rate and fps limited to 29. and GPU temp only max upto 75c.
