Hi, I recently Bought an Asus P6X58D Premium motherboard. When I got the motherboard the power & reset buttons on the motherboard light up when the psu is plugged in but when I press the power button it makes a hissing sound & doesnt make any attempt to turn on. The DRAM_LED light also flashes for a second. After it makes the hissing sound if I keep pressing the power button the board does nothing. Ive tried different ram, 2 different working power supplies & clearing the cmos & still have the same issues. Any suggestions?
