This is my first system im building from scratch and for some reason when i turn it all all of the normal light light up for about 7 seconds then everything goes off. the cpu/psu fans spin. i hear the hard drive startng up. ive tryed reseating the ram. ive removed my gpu for extra measures. nothing appears on screan while its starting up.
start with the simple opsies..check that the 4 pin pci power plug is plugged in near the cpu. also make sure you used the motherboard standoffs to keep the mb from shorting out. if you did use the standoffs look to see if the metal fingers of the mb shield are shorting the mb out..on the bottom or in one of the ports. if there a bios rev sticker on the cmos or mb look for it. the stock bios is 1.1 the newest bios is 1.3. there was one update 1.2 for ram. if the bios is old try running with one stick of ram and see if the mb posts. if not try booting the mb outside of the case on the mb box. if it still rebooting..could be two issue...mb does not like the ram or the power supply has an issue. with the ps try plugging one case fan into it and do the green wire tests. (with the mb unplugged from the ps and your drives). if the power supply fan or case fan twitches with the green wire tests..may have bad power supply. if you put in another ram stick and the mb still looping...power off the mb..pull power from the wall and check under the cpu for bent pins.
