  1. windows is not running, i have got DM bootable cd also, wen i start my computer, it shows error message "operating system not found"
  2. sounds like there are multiple partition on the drive, do you have a low-level format option in your BIOS?
  3. i dont know much about hardware, but i have got DM cd, and i have done zero filling with it, but again showing same capacity. yes there is low level format option in DM cd,but if it cant solve my problem, wts the other solution,coz i am at cyber cafe, tel me the solution so tht i can try it at home.
  4. when i boot my system, bios shadowed,is also shown and then operating system not found error occurs.
  5. Boot off the XP disk, start the setup, remove any partitions on the disk when you get to that part, create a new partition, format it. Finish setup.
  6. I think so anyone cant get my problem, these solutions are not working, please read my all posts in this thread and then give me the solution for possible problem.
  7. What is a DM CD?

    tokencode has given you a place to start. Put in a bootable Windows CD and select the CD drive as the boot device.

    Once the initial setup loads, use it to remove all the partitions. Then continue to reinstall Windows.

    If you cannot boot from the CD, you may have a hardware fault. That will take you through a different troubleshooting path.

    In that case:
    Work systematically through our standard checklist and troubleshooting thread:
    I mean work through, not just read over it. We spent a lot of time on this. It should find most of the problems.

    If not, continue.
    The following is an expansion of my troubleshooting tips in the breadboarding link in the "Cannot boot" thread.

    I have tested the following beep patterns on Gigabyte, eVGA, and ECS motherboards. Other BIOS' may be different, but they all use a single short beep for a successful POST.

    Breadboard - that will help isolate any kind of case problem you might have.

    Breadboard with just motherboard, CPU & HSF, case speaker, and PSU.

    Make sure you plug the CPU power cable in. The system will not boot without it.

    I always breadboard a new build. It takes only a few minutes, and you know you are putting good parts in the case once you are finished.

    You can turn on the PC by momentarily shorting the two pins that the case power switch goes to. You should hear a series of long, single beeps indicating memory problems. Silence indicates a problem with (in most likely order) the PSU, motherboard, or CPU. Remember, at this time, you do not have a graphics card installed so the load on your PSU will be reduced.

    If no beeps:
    Running fans and drives and motherboard LED's do not necessarily indicate a good PSU. In the absence of a single short beep, they also do not indicate that the system is booting.

    At this point, you can sort of check the PSU. Try to borrow a known good PSU of around 550 - 600 watts. That will power just about any system with a single GPU. If you cannot do that, use a DMM to measure the voltages. Measure between the colored wires and either chassis ground or the black wires. Yellow wires should be 12 volts. Red wires: +5 volts, orange wires: +3.3 volts, blue wire : -12 volts, violet wire: 5 volts always on. Tolerances are +/- 5% except for the -12 volts which is +/- 10%.

    The gray wire is really important. It should go from 0 to +5 volts when you turn the PSU on with the case switch. CPU needs this signal to boot.

    You can turn on the PSU by completely disconnecting the PSU and using a paperclip or jumper wire to short the green wire to one of the neighboring black wires.

    A way that might be easier is to use the main power plug. Working from the back of the plug where the wires come out, use a bare paperclip to short between the green wire and one of the neighboring black wires. That will do the same thing with an installed PSU. It is also an easy way to bypass a questionable case power switch.

    This checks the PSU under no load conditions, so it is not completely reliable. But if it can not pass this, it is dead. Then repeat the checks with the PSU plugged into the computer to put a load on the PSU.

    If the system beeps:
    If it looks like the PSU is good, install a memory stick. Boot. Beep pattern should change to one long and several short beeps indicating a missing graphics card.

    Silence, long single beeps, or series of short beeps indicate a problem with the memory. If you get short beeps verify that the memory is in the appropriate motherboard slots.

    Insert the video card and connect any necessary PCIe power connectors. Boot. At this point, the system should POST successfully (a single short beep). Notice that you do not need keyboard, mouse, monitor, or drives to successfully POST.
    At this point, if the system doesn't work, it's either the video card or an inadequate PSU. Or rarely - the motherboard's PCIe interface.

    Now start connecting the rest of the devices starting with the monitor, then keyboard and mouse, then the rest of the devices, testing after each step. It's possible that you can pass the POST with a defective video card. The POST routines can only check the video interface. It cannot check the internal parts of the video card.
  8. You will get the operating system not found if you never installed Windows on the computer, and you never put in exactly what happens when you try to install. List exactly what happens and what you do from when you boot the PC with the XP disk.
  9. I have got my problem's solution from my friend and my own hardwork. Partition was destroyed by a severe net virus. Please help me that, which is best antivirus which can protect my pc from internet virus and spywares also.
  10. Check out Eset Nod32 for a fast and good AV program
  11. Thanks
