    Hi,

    I read some posts related to my problem, but until now I was not able to fix it.

    When I turn on my computer there is no video signal in my display adapter. But when I press the RESET button, the signal is established and sometimes I get this message:

    "Overclocking failed! Please enter... F1 or F2...etc", and then, independently of my choice the computer turns on normally.

    The same happens everyday after a small period of time turned off.

    What I have already done:
    - Changed the CMOS Lithium Battery;
    - Applied Clear CMOS;
    - Changed the voltage and overclock in the mobo BIOS;
    - Checked the processor and mobo temperature;
    - Changed the boot priority options for graphic cards (AGP);
    - Updated the mobo BIOS;
    - Cleaned the cards terminals/contacts;

    But the problem is still bothering me.

    Config:
    Mobo: P4S800D-X
    Processor: Intel P4 2.8G HT
    Memory: Two 512 Mb DDR PC3200
    Video: RADEON 9600 256Mb
    CD+DVD
    HDs: Samsung ATA 80Gb and Seagate SATA 250Gb
    Power Supply: 400W - 12V-17A

    Have you tried removing one stick of RAM, testing the RAM, or just trying different RAM? Asus boards will exhibit this symptom if the RAM is not compatible, overclocked, or faulty.

    1. I ran the Memtest86 - http://www.memtest86.com/. And got no errors.
    2. Then I removed one stick, then the other one, and the problem still remain.
    3. About trying a different RAM, this I can't do by now.

    I noticed that my power supply makes a buzz sometimes. Is this normal?

    Thanks for all the help.

    No, it shouldn't buzz. A faulty power supply could be the problem, you'd have to swap it out with a known good one.

    Hi Triple6, Thanks for all the effort helping me. I was lucky to realize that there was a buzz coming from the power supply.

    I changed it and everything is running quietly and smooth. How nice is that?
