The unfortunate incident happened recently as my PC was lying in idle condition for a month or two since my monitor was conked off. I got a new LCD yesterday but when I attached it to my PC it show some garbled colour boxes & thats it. I switched off the computer & opened the cabinet, removed the graphics card only to find a rodent shitting inside my cabinet. It shitted on the back PCB of the graphic card. Though not much but still not the card got greasy. I cleaned the card gently with a soft hanky & then have kept it outside. I will now keep it in sunlight tomorrow to dry up. What else should I do guys? Is spraying WD-40 recommended?
