Ok i just bought a ecs pt890t v1.0 and a gig of 667/533 and the sytem takes 533 and new pc e video card 256 and a 3.0 775 ht processor. well i have pluged every thing in and i get no video so i thought because i had a old power supply maybe wasn't enough to handle it so i went and bought 450 watt today didn't fix the problem i have cleared c-mos nothing. i know i have had ram that has caused problems with that and figured it out tried to different video card same thing motherboard boots fans kick on cd roms and drives. just wondering if any of you think its the motherboard or the processor or ram but thats new.
