Upon installing another harddrive in my pc, i inadvertently knocked a tube out of my liquid cooled system. This never leaked until (obviously) under pressure sprayed coolant all over my MB and graphics cards. I immediately powered off, took out and dried off all parts, but once reassembled i'm getting a continous beeping. This i believe means a power issue? I have checked my psu with a tester and all lights except the -5v is lighting up. Does this add up and is it simply a new psu i need? Everything else lights up and powers on fine, but i cannot get onto windows. Any advice would be greatly appreciated!
