Solved Start up Problems Tags: Power Supplies Components Last response: March 16, 2011 9:42 AM in Components Share PaqMan9 March 14, 2011 9:50:43 PM On Power up, lights come on and fans spin for 1 second, then everything powers down, and starts up normally a second later. This started after I made upgrades including, MB CPU, PSU, OS and RAM Computer: Asus Sabertooth P67 Intel Sandy Bridge i5 2500K Corsair XMS 3 (2x2GB) Corsair 600W PSU nVidia 9800 GT WD 6 Gb/s 640GB HDD w/ Win7 64-bit I am having no performance issues, but I doubt this cycling is good for my PC. Any recommendations? Side note, I received my replacement MB today from Intel. I will be swapping it in the next day or so.

If not, wait for an updated BIOS to come out. PaqMan9 March 16, 2011 9:42:37 AM Thanks. I installed the replacement MB last night and it came with the latest version of BIOS and the hiccup at power-up has gone away. Can't find your answer ? Ask !
