    I think I may have fried my motherboard.

    I recently got a new computer case and installed my Asus a7n8xe deluxe into it without using standoffs. When I tried to boot it up, I got nothing. No fans spinning, no beeps, no POST, nothing. When I realized what I had done, I quickly removed it and installed the standoffs. Now, I still get no beeps, however the fans spin (they are geting power from the MB) and the LED on the motherboard lights up and the power LED lights up. Nothing else happens. No POST. No nothing.

    Is this thing toast? Is there any other damage that I may have caused to the machine or its components (hard drives, processor, memory, etc.)?

    Please help

    I would say there is a good chance you broke the board. Just screwing it down without standoffs can break traces and or solder on the board.
    To test it, pull it from the case and try for a post outside of the case.

    Pull everything out of the case. Place the board on a non-conductive surface ie the mb box works well. Connect your power supply. Install your video card; making sure it is fully seated. Have just one ram chip installed along with the cpu / hsf. Connect the monitor to the video card. Power on your monitor and use a small screwdriver or other small metallic item to jump the power switch pins on the board. If it powers up and you get a display, great. If not, you will need to swap each part with a known working part ie cpu, board, ram, video, and power supply.

    Just for future reference here is how you mount a new board or install a new case.
    1 Pull the IO plate from the case.
    2 Place the board in the case and use a sharpie to mark the case where you need to install standoffs.
    3 Remove the board and install the standoffs.
    4 Install IO plate
    5 Place the board on the standoffs and slide it into the IO plate
    6 Secure with the screws provided.

    RMA the MB if it's still under warranty.

    ;) Only if he is very sensitive or standing in water. I have been zapped by 24v when working on a furnace/AC but only when I was either standing in water or working outside in the rain.

    Then again, I am not too sensitive. I have been hit by 240v a few too many times as a "young" fellow. I now double check anything I am working on. I once pulled a disconnect only to find the guy that installed it put both sets of wires on the hot side.

    Can I say electricians helper. :eek: :D

    Thanks for the tips. I tried your suggestion and had no luck. I guess I’ll have to try the RMA route.

    Only if he is very sensitive - Must be me!

    I can feel 12 volts in a case not touching anything and wearing rubber sneakers. Its a slight hum almost (thats how I can decribe it almost like a virbation with a buzz and my hairs start to stand up slightly).

    But then again I make static electricity all the time just standing up guess I am just lucky is all (yeah right).

    Follow the directions about how to install a board in my above post. You should be fine.

    A 12V shock is so little that you'd have trouble noticing it. :D

    My sentiments exactly. I have never felt anything under 24v, and even with 24v I had to be wet. :D

    Well, if I stick a 9v battery on my tongue I feel it. :eek: A bit of a sour taste. :D

    Keep away from high voltage, high amp situations. :D
