I have an Asrock X58 Extreme with Core i7 920 450w power supply geforce 9600 vid card, now I did the build from scratch into a brand new tower everything is nice and tidy etc etc, However After the system runs for a period of time not more then 3min it just turns itself off. Each time it powers up it shuts down even quicker. 1st power up runs 3min 2nd power up runs 1min 3rd power up runs 30sec etc etc. Cmos Posts 00 as code which to my knowledge is Norm to run OS which would tell me its not a MB issue unless I am wrong. I am trying to get a temp reading before the sys shuts off. Any Ideas?
