Computer autoshut off during game.

[yojunhao]

I've gotten this issue just today evening. Which is after I click the power button of my cpu, my computer will turn on and run for 1-2 secs b4 shutting off all the way until the main power switch is off. So I decided to unplugged all cables from my cpu and then turning it back on 5mins later and it work. But after playing Marvel heroes for a short 5mins, it shut down by itself again. I did not occur any sudden shut off of my computer before and this evening was my 1st.
Did system restore, did not work.

yes. Those molex connectors. Check whether your psu and cpu heat sink fan are turning.

depend on when u bought the system and from which shop. if within a week or two the shop might not charge any. else i'm guessing might be around $20?
