I plugged in every one of my cables right into all of my components except the 8 pin CPU power supply cable. i started up the computer and everything started spinning up for like 1 second and shut back down again except for 1 led near the 24 pin motherboard power connector. once i connected the 8 pin CPU power lead after i noticed i was missing it, nothing would start up except for that one led. Is this a power supply issue or a more expensive one like a new motherboard or even CPU?
