  1. Hi there , ive got a little problem here .

    2 Days ago , before i went to bed i shutted off my computer by the good way , aka the the Shut down button on the computer SCREEN .
    When i woke up the day after , i tried to turn on my computer . No results = /
    My CPU Fan is working , as well as my Video fan , i can feel that my hard drive is rolling too !
    BUT
    That's it . Theres is no beep like usual when the computer starts .
    Nothing on the screen , no light in my mouse happening either .

    Did anyone ever seen/heard about that ? Cause none of my friends did = /
    Any help from anyone would be gladly appreciated
    Thanks

    It sounds to me like the motherboard has given up to the ghost. The reason I'm saying this is because your HDD is firing up, your CPU fan is working, and your GPU fan is firing up. The power supply is clearly working so thats not an issue in my mind. The fact nothing is happening on screen and POST is non-existent makes me think something is wrong with the motherboard.

    If it was me, I would check the manual for the motherboard and clear the CMOS (I think its called that) or move the jumper to reset the motherboard if it has one.

    Then try and boot again.

    I'm not 100% certain though, but I'm sure others will be able to confirm or deny my comments shortly. :)

    As im not a genius at all in computer terms , id like to know what is the CMOS . and how to move/reset the jumpers , or what it looks like lol
    My mother is a Asus P5Q SE

    I was gonna post a picture or a link of it , but apparently i need 5 posts minimum for that lol

    I forgot to say that right now , even tho my computer is not on , theres a green light on my motherboard .

    I've attached the procedure taken from your motherboard manual.

    This will also be of interest to you (taken from Asus website under troubleshooting for no POST:

    No POST


    1 the power LED is on

    1.1 Make sure all cables are connected well

    1.2 Please clear CMOS to have a try(refer to motherboard manual for details)

    1.3 Keep the necessary components ( a CPU, a memory, a graphic card )on board to test

    1.4 If there is still blank screen, please connect the connector of speaker to check if there is any beeps

    1.4.1 If there is no beep, please contact your retailer for a check

    1.4.2 If there is beep, please try to judge from the beep code as the following steps, if the problem still remains after the troubleshooting, please contact your retailer for a check.

    1.4.2.1 Memory issue: Beep (1 long 2 short)

    A Clean the Golden Finger of memory

    B Clean the memory slots

    C Leave only one memory stick to test

    D If convenient, please change different memory to test again

    1.4.2.2 Graphics card issue: Beep (1 long 3 short)

    A. Clean the Golden Finger of graphics card

    B. Clean the graphics card slots

    C. Try to test the onboard graphics card if there is onboard VGA integrated

    D. If convenience, please change different graphic cards to test again

    1.4.2.3 CPU issue: Beep (5 short)

    A. Check whether the CPU is in our CPU support list

    B. Check whether there are any damagers of your CPU or CPU socket.

    C. .Check whether the CPU fan is correctly connected

    D. Check whether the ATX_12V power cable is connected well

    E. If possible try to test with another CPU

    1.5 If the PC could POST after the troubleshooting as the steps 1.3, please plug components back one by one to find out which one may cause this problem



    2 the power LED is off

    2.1 Make sure the power cable which connects to the front panel is well

    2.2 Please swap a power supply for a try if possible.

    2.3 If the problem still remains, please contact your retailer for a check.

    Sorry for the formatting... lol.
