    I went to start my laptop and it started up as normal but then got to the "Starting Windows" screen and is frozen.

    Tried to start in safe mode and when pressing F8 it went into the usual fill loading and then froze half way through the load.

    Pressed and held enter while it is restarting to get to the recovery screen. Choose to do a recovery and it tells me a recovery error. It does not explain what the error is just a recovery error.

    Started again with F2 for the bios setting. Changed the boot order to boot from cd, saved and restarted. It gave me the "press any button to boot from cd/dvd" message so I did. You can hear it booting from cd and the screen is loading files.

    That is the farthest I get it then goes to the "Starting Windows" screen.

    It will not do a boot from cd.

    What CD are you trying to boot from?

    Have you tried the same CD in another system?

    Is the CD surface in good condition?

    I suspect from the symptoms that your hard drive or other item of hardware is failing and either the CD or your CD player are defective.

    Download and burn a Windows 7 DVD on another PC and see if that will work:

    Please go here: Windows 7 ISO downloads and download the version of Windows 7 that matches what you have on your PC.

    If you have downloaded the ISO on a Windows 7 PC right click the ISO file, select Open With, then select Windows Disc Image Burning Tool then follow the prompts.

    For PC's using other versions of Windows you must burn the ISO image to a DVD using an ISO image burner, copying the ISO to a DVD will not work, if you do not have an ISO burner download this free software and follow the instructions below to burn the disc.ImgBurn When you install ImgBurn make sure you uncheck any boxes offering bundled software.

    Install the program and start the application. Select the top left hand option to burn image file to disk and then on the next window click on the small yellow folder icon and browse to the ISO file you wish to burn. Then click on the two grey discs with the arrow in between (bottom left) and leave it to complete the operation.

    I have a new copy of windows 7.

    I have tried it in a different laptop and yes it works.

    In this laptop when I put the cd in and startup you get the "boot from cd screen" push any button and that is when the cd will start.

    On the screen you see files loading and when the files are loaded then it goes right back to the "Starting Windows" screen and freezes.

    Just to clear up a point of terminology, if it is the Windows 7 disc you are referring to as a CD, it isn't, its a DVD.

    As the system is having a problem booting from the hard drive and from a Windows 7 DVD then the first thing I would check is the memory. Do you know how to access the RAM modules, they will most likely be under a cover on the base of the laptop. If there is only one module we will have to try something else but if there are two, remove one of them and try to boot the system, if no change swap them over and try again. Let us know the outcome.

    Yes I see it now. You are right it is a DVD.

    As for the memory, there is only 1.

    Ok, please try and run this test on the memory.

    Download Memtest86+ from here
    If you wish to run the test from a USB flash drive use this link Auto installer for USB key
    When the download is complete right click the file and select Extract Here and burn the image to a CD.

    In windows 7 right click the extracted file, select Open With, then select Windows Disc Image Burning Tool then follow the prompts.
    For all other versions of windows (if you do not have an ISO burner) download this free software. ImgBurn
    Install the program (make sure you uncheck any boxes to stop any bundled software from installing) and start the application. Select the top left hand option to Write image file to disk and then on the next window click on the small yellow folder icon and browse to the ISO file you have downloaded. Then click on the two grey discs with the arrow in between (bottom left) and leave it to complete the operation.

    Testing

    • Boot the PC into the Bios setup and set the CD/DVD drive to 1st in the boot sequence.
    • Insert the disk in the drive then reboot and the disc will load into dos.
    • Leave the test to run through at least 8 passes or until it is showing some errors.
    • If errors show in the test, stop the test and remove all but one of your RAM sticks then start the test again. Repeat the test on each stick until you find the one that is faulty.

    NOTE: This is a long slow test and for convenience should ideally be run overnight.

    The memtest will not be 100% accurate but should easily detect any major faults.

    I need to be able to do a new install of windows 7 and I can't get it to start. CD/DVD player is working but the program will not start

    Your CD/DVD drive may appear to be working, but that does not prove it is reading the disc. Try running the memtest using a USB Flash Drive. You will obviously need to create the bootable Flash Drive on another PC and then set the Bios boot order so USB is in first position.

    Same with USB HDD.

    Sorry to say we have reached a dead end. Without being able to boot the system from any source we can't run any kind of diagnostics or even re-install Windows.

    I can only guess the system has a hardware problem. This PC now needs a hands on approach as there is nothing else we can do from this forum. I can only suggest you now have it looked at by a recommended computer repairer.
