    Yes, I have the xp card that came from Dell with the machine. But I am not able to boot from it.

  • burkejt Feb 28, 2009

    Even though I have two optical drives, the optical cd drive does not read a dvd. When I bought the pc I asked for a drive that read both cd''s and dvd's, but this isn't the case. The computer only boots from the cd drive and the operating system dvd is a dvd read. Is there a way to get around this?

  • burkejt Feb 28, 2009

    I did change this in the boot menu. Is this the same as the bios screen?. Thanks alot for your patience.

  • burkejt Mar 01, 2009

    I am going to install another dvd optical drive and hopefully I will be able to boot the operating system off of that. Then I will get back to you. Thanks again.

    Hello, I managed to boot from the win xp reinstallation disk and got to a windows c: prompt. I would appreciate you telling me where i go from here, for i did not want to reinstall the operating system and lose all my data.

  • burkejt Mar 03, 2009

    After doing the chkdsk /r, it did not come back with a chance to enter a Y. After rebooting it came back with blue screen with errs.


    IIs there anything else I can try? Thank you for your time.

    I removed the ram memory and reinstalled several times and rebooting, but it didn't help. I am just going to reinstall the operating system and accept my losses. Than you for all you help.

I seem to be a little late, as you've indicated you're going to re-install, but I just had this problem with a Dell Dimension machine. Microsoft says it's probably a RAM issue, but it wasn't in my case. The problem was that the system hive was corrupt. Using a BartPE disk I was able to log in and replace the system hive with one from a few days earlier.
For those who don't know how to do this, but do have access to another computer or a BartPE CD or a UBCD CD, here's the steps:
Once you are able to access the hard drive, using another system and slaving it, or by using a BartPE CD or UBCD, navigate to C:\Windows\System32\config. Rename the SYSTEM file there to SYSTEM.old.
Next, navigate to the C:\System Volume Information folder then to the _restore{blah, blah, bunch of numbers} folder. If there's more than one, use the Date Modified information to pick the most recent one. Next, pick an RPxxx folder, where xxx is a number, that is a couple of days older than when the error occurred (check the Date Modified of the folders), then open the snapshot folder. Copy the file _REGISTRY_MACHINE_SYSTEM. Go back to the C:\Windows\System32\Config folder and paste _REGISTRY_MACHINE_SYSTEM into that folder. Now rename the _REGISTRY_MACHINE_SYSTEM file to just SYSTEM (no extension).
Reboot the system normally - hopefully the error is gone.

You're going to need an XP cd, NOT a restore cd.

When / If you get one, let us know and we'll go from there.

    You've got to change the boot order in the bios screen.

    Usually if you press the DEL key or the F10 key when you startup the computer it will take you into the bios.

    If you look at the bottom of the screen you should see a message that tells you which key to push.

    Once inside you've got to change the boot order so that the CD / DVD drive is the first boot up device.

    Let me know if you have any trouble doing this.

  • RescueTechLA
    RescueTechLA Mar 01, 2009

    Yes, it's the same thing.

    Don't worry about my patience. I'm here to help :)

    Have you had any problems with the cd / dvd drive in the past?

    Can you describe exactly what the CD you're trying to boot up has written on the cd?

  • RescueTechLA
    RescueTechLA Mar 03, 2009

    OK once you're there type:

    chkdsk /r

    press enter

    Message will come up (most of the time) saying disk is locked, blah, blah, blah.

    Press the "Y" key.

    Press enter.

    type: exit

    press enter

    press Ctrl + Alt + Del

    Choose the Shutdown Tab

    Shutdown or restart the computer.

    Let the Disk Check do it's thing.

    Hopefully you'll be able to get back into Windows.

    If you are successful backup your data immediately.

    Let me know what happens.

  • RescueTechLA
    RescueTechLA Mar 04, 2009

    That message usually indicates a problem with memory. Try puling out the memory and then reseat it.

    Boot the computer with just one module. If you get the same message, try the other module.

    Hopefully it's just some bad memory.

    Ahh man that stinks. Try installing Windows over itself when you do the install. That way you'll keep any files you previously had. If it doesn't work a format / re-install might be in order.

    Let me know if you have any other questions or problems.

    Best of luck!

Will not start up

hi , Reuben

I would suggest you try safe mode.
Safe mode is a troubleshooting option for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. The words "Safe Mode" appear in the corners of the display to identify which Windows mode you are using. If an existing problem does not reappear when you start in safe mode, you can eliminate the default settings and basic device drivers as possible causes.
If you don't know the cause of the problem, you can use the process of elimination to help you find the problem. Try starting all of the programs you commonly use, including the programs in your Startup folder, one by one, to see if a program might be the cause of the problem.
Follow the steps to boot the computer in safe mode with networking:
1. Restart your computer if it is powered on.
2. Tap the F8 key after your computer initially powers on.
3. Once you see the Advanced Boot Options menu you can stop tapping.
4. Use the up/down arrow keys to highlight your selection.
5. Select Safe Mode with Networking and press Enter.
6. You should see drivers loading, and then please wait.
7. You should then be at the Welcome Screen.
8. Logon to your computer using an account with Administrator privileges.

What is the difference between windows 7 editions: starter, home basics, home premium,ultimate, professional,interprice?what is the difference between service pack 1 & 2???pc

Since October 31, 2013, Windows 7 is no longer available in retail (except for the Professional edition preinstalled):[6]
Windows 7 Starter Windows 7 Starter is the edition of Windows 7 that contains the fewest features. It is only available in a 32-bit version and does not include the Windows Aero theme. The desktop wallpaper and visual styles (Windows 7 Basic) are not user-changeable. Microsoft originally intended to restrict users of this edition to running three simultaneous applications but this limitation was dropped.[7]This edition was available pre-installed on computers, especially netbooks, through system integrators or computer manufacturers using OEM licenses.[1][8][9] Windows 7 Home Basic Windows 7 Home Basic was available in "emerging markets", in 141 different countries.[10] Some Windows Aero options are excluded along with several new features.[1] Home Basic, along with other editions sold in emerging markets, include geographical activation restriction, which requires users to activate Windows within a certain region or country.[11] Windows 7 Home Premium This edition contains features aimed at the home market segment, such as Windows Media Center, Windows Aero and multi-touch support.[12] Windows 7 Professional This edition is targeted towards enthusiasts and small-business users.[1] It includes all the features of Windows 7 Home Premium, and adds the ability to participate in a Windows Server domain.[1] Additional features include support for up to 192 GB of Random-access memory (increased from 16 GB),[13] operating as a Remote Desktop server, location aware printing, backup to a network location, Encrypting File System, Presentation Mode, Software Restriction Policies (but not the extra management features of AppLocker) and Windows XP Mode.[1] Windows 7 Enterprise This edition targeted the enterprise segment of the market and was sold through volume licensing to companies which have a Software Assurance contract with Microsoft.[1] Additional features include support for Multilingual User Interface(MUI) packages, BitLocker Drive Encryption, and UNIX application support.[1] Not available through retail or OEMchannels, this edition is distributed through Microsoft Software Assurance (SA).[1] As a result it includes several SA-only benefits, including a license allowing the operating of diskless nodes (diskless PCs) and activation via VLK.[14] Windows 7 Ultimate Windows 7 Ultimate contains the same features as Windows 7 Enterprise, but unlike the Enterprise edition, it was available to home users on an individual license basis.[1] Windows 7 Home Premium and Windows 7 Professional users are able to upgrade to Windows 7 Ultimate for a fee using Windows Anytime Upgrade if they wish to do so.[1] Unlike Windows Vista Ultimate, the Windows 7 Ultimate edition does not include the Windows Ultimate Extras feature or any exclusive features as Microsoft had stated.[1] All editions will receive Mainstream Support (new features and bug fixes) until January 2015 and Extended Support (security updates) until January 2020.[15]

How do i turn off the HDD

What happens when entering the sleep mode is the drives will be turned off and the present state will be kept in memory until awakened. While the system is active the power scheme will prevent the drives from idling down after so many minutes with the never turn off setting applied.

With the turn off drives after the default 20minutes of inactivity that doesn't mean all drives turn off at the exact same time. I've never come across any reference for changing the power plan option for individual drives. But I can point you at the guide for the power plan settings with one instruction on drive settings to apply prior to entering the sleep mode.

hope that helps if not let someone here know.

How to enable bluetooth

Your computer has to have a bluetooth radio. You can check
Control Panel > System and Security > Device Manager
Do you see a Bluetooth Radio listed?

If not, you don't have BlueTooth on your computer so you will have to add a BlueTooth device by plugging one into a USB port.

If you have a BlueTooth radio, go to Control Panel > Hardware and Sound > Device and Printers > Add a Bluetooth Device

This option is used to connect a blue tooth device (e.g. bluetooth headphons) to your laptop through your bluetooth radio.

See this Windows web page for more information.
Set up Bluetooth enabled device

I will respond to any additional questions you have.

No disc problem

You would only receive that error if your player in unable to read your disc, basically saying there is no disc in the unit. This problem arises mainly due to the Optical Pickup(laser) probably failing. For more information, please visit my website at Thank you.
