Tried to install my new P4PE last night, but it would not power up. I tried hooking up mobo outside case in case of a short. Cleared CMOS. Verified in another rig that my Ram, and PSU are functioning. It appears the red AGP warning LED is on. This prevents you from installing a 3.3V Video card. My Video cared is a leadtek Gf4 Ti 4200. should operate at 1.5V. Anyway tried everything won't power up. Any suggestions?
