Well i have recently bought a new motherboard asus m5a97 r2.0 i installed all components but i got no image and everything inside the pc was working, cpu fans everything i also get a beep code that is 1long beep and 3 short beeps, the manual says thats no VGA detected, that grafic card was working just fine on a different mobo, i unplugged the psu power cord from the pc and waited a minute then i turned on the pc again and it started just fine i installed windows then all the sudden it turned off when i tried to turned on again i got the beep code so inplugged it waited a minute then put it back in and it started again but this time the cpu fan wouldnt go over 3000rpm even though the cpu temp was going over 70º C, i tried a different psu but this one is less powerfull everything started fans everything but got the beep code and no image and couldnt get to boot the pc with the less power psu, i really dont want to buy a new psu if that is not really the problem here, would appreciate any suggestions or advice
My pc spec

Mobo m5a97 r2.0
Amd fx 8150 3.6 ghz
Amd radeon hd 7750
Psu:Extreme power plus 600w
Corsair vengeance 8gb ram (2x4gb)
 
Could there be a loose cable or maybe the video card isn't seated firmly into the slot? Maybe remove it and try reinstalling it physically and see if the problem still happens. Check all the power cables to the motherboard and the power cable to the video card. See if it's loose or anything.

No there isnt any loose cable and the graphic card is firmly inside the slot and i have reinstalled the graphics many times aswell i even try the second pci e slot which is x4 but wont start it will only starts at the x 16 pci e slot, aslo whenever i get the beep code just a little before that the pc kinda power down a bit so i gotta unplug it wait a minute and then plug it back in order for the pc to start, i am also thinking that could be a bad mobo
PD: i can reboot my pc as many times as i want, the problem comes whenever i turned it completely off

Today i took the mobo to the seller to make sure is not the mobo that is broken, my next step if the mobo isnt broken is to get a good psu, hopefully that should fix the problem, else i will post here.

I will keep this thread updated just in case someone is having this same issue.
