I own a computer that for no reason at all, will just shut off. What will happen is that when I am doing something on my computer, such as playing a game or browsing this website, my computer will suddenly turn off. I can't turn it back on from the front after it turns off, I have to go to the back, turn the power supply switch off, then turn it back on. After doing that, I can turn my computer back on from the front. Sometimes, it dosen't do this at all. Can someone help me?
