I recently bought an Asus A8V-VM SE Motherboard. It arrived today. I quickly installed it into my case, inserted the new AMD Athlon 64 3800+ X2 (dual core) processor, and heat sink. I connected the cases wires for power button, reset button, HD LED, PWR LED and Speaker to the motherboard. I wanted to do a quick test. (the reason I got the new motherboard was because my old one died...or at least I'm hoping it did)..... I plugged in the power cable to the PSU. The green light of happiness turned on on my mobo. So far so good. I hit the Power button on my Case....and nothing happens....nothing at all...I've double checked to make sure the wiring is correct. it is. I've swapped reset button with power button, just in case. Still didn't work....I even wondered if the motherboard was too clever...So I installed everything else into the motherboard, RAM, GPU, all other cables. etc. Still Nothing. Also got out my old PSU (still workng)...and tried that. The green light on the motherboard came on. but still nothing worked through use of the power button. Should I presume this motherboard is DOA? or is there anything else someone might want to suggest that could help. I've tried to be as detailed as possible. And any suggestions are welcome. Thank You in advance.
