I spilt a can of coke all down the inside of my PC while it was on (I leave my case open for switching hard drives). Switched it off straight away, dried the motherboard and cards, worked fine. The only thing I had grieve with was the Hard Drive, seems like the coke was heating up, gwetting sticky and jaming the disks. Soaked it in 110% alcohol, left it for a week. Brand spanking new.
