That's the sound of my PSU frying as I turned on my gaming PC last night :(
Have a new one ready to be fitted later tonight, but just crossing my fingers that the cpu and motherboard have survived. If not it's going to be an expensive week and no Civ 5 or AoC to see me through either!
Update: All is now working fine. Replaced the psu and luckily everything else seems to have survived!
