Custom build problems

[mosab109]

I just built a custom pc and tested it. First time it worked like a charm, i got video output and the startup screen and everything. However when I turn it on now it runs for about 5 seconds then turns off for about 2 seconds and then on again in an (to my knowledge) infinite cycle... What to do?

Try reconnecting the 24-Pin cable and make sure it is snug. That happens a lot.

What are your specs?

I managed to fix it through going over every component yet another time making sure everything was snug, and then finally pressing the MemOK! button on the motherboard... Thx for suggestions
