Videop Card pixel errors

so last week i spilt some soda inside my computer and cleaned it up it was working right then i started getting some pixel discolorations, wasnt my moniter because i hse it with 2 different setups and i screenshotted it so its something with the video card, so i got an RMA number for the return but while running it a few days later right before im going to send it out the blue pixels which were all over my screen are gone. I'm really confused should i still RMA the card, they may find nothign wrong with it and it would just be a waste of money. Suggestions please. My screenshot which i took doesnt have the discolorations in it either i am so lost.banghead
