Help. New build. Connect PSU to mobo and turn on PSU power. Mobo fires without post or boot. Case fans, cpu fan and vid card fans all spin. Case switch does nothing (doesn't even need to be connected). Reset either. True on bench test or in the box. Cant find anything online. Anyone seen this. Im afraid something is shorted in mobo. Thought CPU and memory, but cant see how this would allow power up. mobo is biostar t5 xe cfx-sli lga; i5-760, and antec 750 watt psu.
Yes, i've used two seperate PSUs ... same issue with both.
Haven't tried the PSU alone idea ... will try at lunch. thx.
Did speak with manufacturer tech rep ... advised clear CMOS (did that already before they suggested - nothing changed) and then remove/reinstall/replace mobo bat ... (haven't tried that - but not sure how that might help) ...
