Hello everyone!I have a problem with my first build gaming pc!It keeps turning on and off ,
First I build it outside the box.. I installed the CPU,FAN,GPU,RAM then plug the 24 pin,8pin and gpu pin of the psu. turned it on using a screw diver and I got the same problem, on and off...This is my first build so I have no idea what it is, For starters I ignored it and install it inside the case thinking it will be okay after I plug in everything.I think I plugged in every cables right ,pushed the power button on the case then there it goes again!On and Off!!

Im a newbie but my theory is the problem was either on the motherboard, CPU,GPU, RAM or PSU...since I had the same problem after building it outside the case. Im leaning towards a defected PSU or damaging the Motherboard without knowing.I want to know if anyone out there know what the problem might be..

Here are a few videos of my first build.

I have no idea what a cmos is, It was never mentioned on any tutorials I have watched, what does it do?
after reading the manual I finally find where the cmos was, I think my mobo didnt come with a cmos jumper though. How will I know if my cmos is in the runs position?
 


If you are missing the CMOS Jumper or the CLRTC jumper as labelled by most motherboards then you'll need to come up with one, did you check inside your motherboard box to see if it fell off?

Your motherboard manual shows you which of the 3 pins are the 2 pins that should be jumpered to put the motherboard in run mode, you put the jumper on those 2 pins.
