video card problems

ever since i installed some copper ramsinks on my video card i have been having a few problems. first, i cant play any games without horrible texture corruption and the screen is all broken and such. next, im seeing pink lines when i go to monitor properties and when using AIM the im, chat, and other icons have pink lines. whats going on? i cant even play games and its rather frustrating.

 

any chance you got thermal adhesive where shouldn't be? Other then that, all i can think of is that the heatsinks arn't contacting properly, insulating the heat and the memory is overheating.

 

i used the thermal tape on the bottom of the heat sinks so i don't think its the thermal stuff.

 

Thermaltape is highly prone to trapping air, so its quite likely that TMM's suggestion is accurate.

 

i took the heatsinks off and still same problem. i even blowed the dust out of the agp slot. there wasnt much in there to begin with. i dont know whats going on but its pissing me off
