My system has been in storage for 3 months. I hooked it hotbox week an when I turned it on it shut down after 2 seconds. No post. After 5-6 seconds it tried to power up again but failed. It will cycle like this until I disconnect power. The case fans and ps fans turn on when I turn the computer on. The cpu fan and vc fan don't but they twitch when it powers off. I reseated the heatsink ad checked all the connections. I powered up with disconnecting the 12v atx to the mobo. It started but with no CPU running obviously. Any suggestions?
