Hello, I just had a new asus a7n8x deluxe MB installed and am having trouble getting my comp to turn on. I also installed a new 350W power supply. My pc will turn on only if i reset the power switch button on the back of the power supply then I am able to push the front power button located on my chassis and my system will turn on. When ever i leave the power supply button in on position and turn off my pc for more than 20 minutes it will not power back on. I get no led light or nothing turns on not even for a sec. Then I must follow the same steps as mentioned to get my pc powered on. But if left off for less than 20 minutes it will turn back on. Weird, I dont know what to make of this . Is this a defective board or is there a setting that may be configured wrong? Note: Once I get my pc on I have no problems and is working fine.
