so iv had my custom gaming desktop for abot 6-7 months no problems. i tried turning my computer on a few days ago and it turns on for a split second then shuts off (led lights and fans go on then off). after it did that if i tried to turn it on again nothing would happen unless i unplug the computer then plug it back in and press the power butten (then it turns on and off again). after a few more tries it finally booted up and i used it for about an hour until it shut off and a message appeared saying "poewr supply surges detected during the previous power on ASUS anti surge was triggered to protect system from unstable power supply". does this mean i need a new psu? the psu i have now is a LOGISYS PS575XBK.
