Installed new ASUS A8N-E mobo last week and it powered on and worked great!
Now the computer will shut down about 1 second into boot! All lights go out!
I have reset the processor, checked the cooler paste and reset the cooling fan. All fans power on when start button is pushed. Reset the memory (1gig) in the blue sockets. Reset the video (ASUS) card. Checked all electrical connections and plugs at fans, hard drive, CDROM's and neon transformer. All were unplugged and reset.
If I keep pushing the power on button for numerous times, kinda keeping the power to the system, it may start up. Sometimes if it does start, it may "click" and shut down anyway. Then I have to start over again.
Boy, any help on this one would really be appreciated!

With all installed you need to tap delete or f8 during boot to set up BIOS for the display type and other devices, also connect the mobo speaker so you can hear any possible error beep codes before it smokes...
CHECK ALL JUMPER ON THE BOARD AND MAKE SURE THE BOIS RESET JUMPER IS ON JUMPER 1-2, SOUND LIKE A POWER SUPPLY PROBLEM NOT ENOUGH WATT TO RUN THE SYSTEM
2ND OPTION, REMOVE ALL WIRE AND ADDTIONAL CARDS, MIN. MEMORY, LEAVING 1 STICK OF RAM, VEDOI CONNECTION , AND THE POWER TO THE BOARD, CONNECT ONE WIRE AT A TIME AND RESTARTING THE MACHINE EVERY TIME UNTIL YOU FIND THE PROBLEM.
sounds like your system is not booting, that may be, obiusly you just have power but that's it...no boot routine. hope somebody else could help on "how to make sure your system can boot again, then the rest.
Sounds like the power supply is overloaded. Is this a new configuration? Start removing components until it powers up. If it still doesn't power up, check to ensure you don't have a short in any of the connectors that you installed components into. Sometimes when a video card, memory DIMM, or whatever, gets installed, there is a chance that a connector pin will get crushed and short out to nearby pins. If none of those work, you might want to try a larger wattage power supply. Good luck.
