|Where was the card when you spilled something on it? What did you spill on it?|
If you spilled anything other than water on it, then you should have washed it off with warm water. You can still do that. No need to wait two months again. Dry it with a hair dryer.
Before you give up on the card, be sure you inserted it completely and firmly. Be sure you connect the TWO 6-pin power connectors.
