Solved Is something wrong with my board? Tags: CPUs Power Last response: August 13, 2012 8:38 AM in CPUs Share wolfrahm21 August 13, 2012 2:14:26 AM I am building a new pc, so far i have bought Mobo: gigabyte z77x-d3h Psu: Aerocool strike x m800w Chassis: cm690II a I connected 5 fans to test the psu via paper clip. It worked fine Then I put everything inside the case and when i powered on, it went on a power on/off loop! Is this normal? There is no cpu yet and no ram! Checked by unplugging everything except front fan and 24 atx power, it powered on and then turned off instantly and thats it... If i connect both 4 pin 12v and 24 pin, it will do the loop again! Is the mobo doa? Or is it just looking for a cPu? I read posts here but I am still not sure about mixed answers! I just wanted to test if proper power is flowing on my mobo... I can power it off thru the pwr button if I press it for 4 seconds.

Without a CPU in place, the computer does not have the ability to do the POST. You will need a CPU and ram in place to POST. | Report abuse DJDeCiBeL CPUs Master August 13, 2012 2:40:07 AM ^ Correct. I'm surprised it does anything at all without a CPU, actually. | Report abuse wolfrahm21 August 13, 2012 2:43:26 AM C12Friedman said:That is to be expected.
