My Computer started to smoke after a few months. My pc specs are i5 4670k,MSI GTX560ti twin frozr,Corsair CX600M,MSI Z97 Gaming 3 motherboard. It's running on a stock cpu cooler and i didn't overclock it. The pc was running fine for months when i suddenly was watching a youtube video i smelled the smoke and panicked and shut the pc down.I was not heavy multitasking at the moment what could my problem be?
