pc powers up but will not boot (no beep at all).

I was running Nvidea NTune and it hung up and i had to hard start it. now I get nothing, there should be some thing I can do to reset the pc.

I'm not to savy with this stuff, thats why I ran NTune. I have powered down and pulled the power plug out. Tried to reboot the pc. Can;t get XP to boot with the pc not starting up enough to load BIOS to change CD as start up.

Any help would be cool, any thoughts.

    I cannot necessarily relate running software and the demise of your PC.

    Try the following:
    1. See if you can boot it from a bootable CD. Normally you try to start and press F12 at the same time to get a boot sequence. This is not a BIOS change. Insert a bootable CD and see if it starts.
    2. Something that can work with a laptop: Unplug the PC. Press the power button for 10 seconds. Do this 10 times. Now plug it back in and see if it starts. I do not know if this technique to discharge capacitors used in starting will work on a desktop.

    Accepted Solution

    NTune may have corrupted some of the BIOS settings necessary to boot your system.  Here is what I would try first:

    Remove the AC power cord from the system.
    Open the case.
    Find the flat silver BIOS backup battery.  It will be found somewhere on the motherboard.
    Unlatch the BIOS backup battery and remove it from the holder.
    Wait an hour.
    Put the battery back into the holder.
    Reconnect the AC power cord.

    Deo volens, this should clear all BIOS settings in the system and put the settings back at the factory defaults.  If this works,  the system should start and the BIOS boot displays should come up.  The system may or may not boot to XP, but at least it will then be possible to help you further if the system won't boot.

    Here is a copy of a webpage that shows how to reset the CMOS and details about ntune and the issues that many are having with it.

    Programs that overclock
    There are programs available for download that will automatically overclock your system. While they may seem easy to use, they will sometime push your system faster without notifying Windows, causing unseen conflicts. They cannot be used for extreme overclockability either, since they "obey" the needs of the computer. For a mild overclock, these programs may be used. The EVGA i650 motherboard comes with a program called nTune, which will detect overclockability and run the system at a speed that it deems appropriate. This is counter productive to achieving the highest overclock possible but will likely stress the system less than running at a higher speed.

    I noticed that the nTune program seems to overclock the settings again after I did so in the BIOS once Windows is loaded. I've uninstalled the program and it's still continuing to do so. System properties will show 2.98GHz for a setting (the actual speed) and CPU-Z will read 2.56 for the same settings (what the BIOS thinks it's running).


    Potential Problems

    While overclocking many you will eventually hit some or all of the following issues:

    1. A Blue Screen Of Death during boot indicates a RAM issue.
    2. Rebooting while in Windows or when just about in Windows may be the result of too low a Vcore or overheating due to excessive Vcore.
    3. A system that beeps or hangs when first rebooting likely has multiplier or FSB configuration that exceeds what the system can handle.
    4. Syntax error that comes on screen when booting indicating a file that can't be found or is corrupt is likely due to too low a Vcore"

    Possible Resolution
    1. Try lowering ram settings, timings, or increase ram voltage if it will withstand it.
    2. Check the bios for system health to check for heating issues or use a thermal probe. Raising the CPU voltage slightly may allow for a full boot ,however, the system is likely not to be 100% stable.
    3.Clear the CMOS and restart making changes to the CPU, voltage, or RAM settings. Clearing the CMOS is accomplished by using the onboard jumpers or removing the CMOS battery. Always remove the power cord before clearing the CMOS.
    4. Raise the Vcore or adjust other system settings. Returning the system bios to "Load Defaults" will often result in a sucessful boot. Make a backup of your critial system files and get familiar with restoring corrupted system files using the Windows XP or Vista disk.

    I completely agree with what BabsHere has said above:

    "While overclocking many you **will** eventually hit some or all of the following issues:"

    NTune is probably exactly like GigaByte's system tuner, and that is exactly what that product did to me -- caused the system to fail erratically.
