    Window's xp, when you turn on the laptop it states Compaq then goes to a blank screen with a cursor blinking in the upper right hand corner

  • specialkim Apr 14, 2008

    the blinker in the upper left hand corner, I had already tried the system recovery, but it didn't work. I don't have a start up disk.

    I THINK U HAV SCAN UR DISK WITH ANY ANTI VIRUS... IF THAT THE ANTI VIRUS MAY DELETE CERTAIN NECESSARY FILES THAT ARE REQUIRED FOR OPERATING SYSTEM TO WORK. SO I SUGGEST U TO FORMAT UR SYSTEM

That blinking cursor is the way in which the BIOS is telling you that Windows is missing - its most critical, core files have been corrupted or deleted during the scan. The only thing you can do is to reinstall using the recovery cd or your own Windows install disk.

Computer has viruses, how to restore to factory setting without restoration cd


Impossible unless there is a Recovery Partition on the hard drive.

Boot up into safe mode and try downloading and installing MalwareBytes and run a Quick Scan.

Turn off the computer, then hit the power button to turn it back on and immediately start hitting the F8 key repeatedly until you see SAFE MODE. Take the Safe Mode With Networking option (this will give you internet connectivity) and let it boot up. Safe Mode will look different to you, the screen will be darker and the icons bigger, this is normal. Open your internet browser, then download and install MalwareBytes and run a Quick Scan.



Go to www.google.com and in the search box type: "Download cnet Malwarebytes" (without the quotes). Download and install malwarebytes from the sites download.cnet/malwarebytes. When the site opens up click on the Green Download button on the left. Do not click the Red Download button, that's junk. When it finishes installing the Gui Interface will open up with an offer to Accept a Trial Version or Decline. CLICK DECLINE you want the totally free version. Run a QUICK SCAN. As it scans, if it finds infections the number will be in red. When it finishes scanning, click SHOW RESULTS. A notepad text document will open up showing you the results. You can close the text document and go back to the Gui Interface where you will click REMOVE SELECTED RESULTS. The objects will already be selected for you. When it finishes removing the objects click ok and it will sometimes reboot your machine.


If the problem still exists after the above steps then you might try System Recovery or just Reinstalling Windows.



System Restore will allow you to select a Restore Point (date and time) to set your system back to when it was working ok. It does not delete any of your data, documents, music, pictures, videos or programs (unless the program was installed after the Restore Date you selected).

System Recovery (sometimes referred to as Factory Restore) will set your system back to when you first purchased it. It Deletes Everything. Most times the System Recovery does not work unless there is a recovery partition on your hard drive created by the manufacturer. If you are trying to recover from a set of cd's most times it does not work.

Instead of doing a System Recovery it's much easier to just Reinstall Windows. Look on your computer for the Certificate of Authentication (COA) Sticker. It will tell you what operating system is on your computer and it will give you the Product Key Code (a series of 5 letters and numbers) that you will need to activate windows. If you don't have an operating system disk, borrow one from a neighbor, friend, relative or co-worker. Just make sure it is the same as your COA Sticker's operating system or it will never activate. Also make sure you get the COA Product Key Code for the disk you borrow because sometimes the system will ask for the one that is on your system and sometimes it will ask for the one from the installation disk.



If you have Windows XP do a Repair Install so you won't loose your data if you want it. Boot from the operating system disk in the cd drive, then when it comes up select the option to Install Windows (don't select R to repair on this screen). Windows will then ask for you acceptance to the license and you will press F8 to accept. It will then search your system to see if there is already an existing windows on the disk. It will find your current operating system and this is when you will select R to repair the current operating system. This will allow the system to keep your documents, music, pictures, data, videos, programs, etc.

My laptop has no operating system on it


Borrow a reinstallation operating system disk or an operating system disk from a neighbor, friend, relative or co-worker. Just make sure it is the same as the operating system that your Certificate of Authentication (COA) sticker on the bottom of the laptop or inside the battery case or you will have problems activating it. Make sure you can read your series of 5 letters and numbers on your COA sticker and also get them for the disk you are using on the install. Sometimes when it asks for the product key it wants the one from your sticker, sometimes it wants the one from the cd used to install.

If you COA Sticker says Windows Vista Home Premium, you can't use a Windows Vista Home Basic operating system disc to do the install.

On start up it loads up and after the acer screen, it says dtwzr compressed, press ctl alt del to restart after doing this it dosent get any further in the start up?


Hi

Try to press F8 when booting up and then it will run your computer at safe mode. Then try to free some space or uninstall programs that might corrupted your operating system. Faulty installed software may harm your computer.

Try also to run the SCAN DISK for checking some errors.

Go to START, ACCESSORIES, SYSTEM TOOLS, SCAN DISK FOR CHECKING ERROR AND WILL FIX AS WELL.

I hope it helps solve your problem. Please post comments if you need more help. Regards

As soon as turn computer on it says operating system not found -- i can get it to go to one other thing and it ask for HDD user password which i have no earthly idea what it can be


1. i hope you have backed up of all your data from the HDD.
2. format the HDD and reload the OS - but this time, make sure that you have atleast 2 partitions.
3. keep all your important in the second (non-system) partition.
4.after you have reloaded the OS, please get a good anti-virus and anti-spyware application and scan your computer regularly with them.

Pc,the product key has expired and I can not access my pc full properties and files. please I neeed help.


Hi I hope I can help, is the computer licensed to9 you, if so call Microsoft and have them activate your operating system. You can still get in under safe mode by holding down the f8 key after the initial boot but before the op system starts, that way you can retrive all of your files incase you have to reinstall the operating system, if you bought the computer with the operating system please let microsoft know this so they can re-activate.
If all this fails you may need to purchase a license for you operating system, with saying that If you need a new license you may consider upgrading to windows 7
Have you ever activated the op or have you had a major hardware change like a graphics card as this will trigger a new activation prompt
Good Luck

I have a operating system not found


This issue may occur if one or more of the following conditions are true:
  • The basic input/output system (BIOS) does not detect the hard disk.
  • The hard disk is damaged.
  • Sector 0 of the physical hard disk drive has an incorrect or malformed master boot record (MBR).

    Note Some third-party programs or disk corruption can damage an MBR.
  • An incompatible partition is marked as Active.
  • A partition that contains the MBR is no longer active.
Contact your hardware manufacturerYour best bet may be to contact the manufacturer of your computer or your hard disk. The manufacturer may have a utility that you can use to perform a more detailed scan for damaged areas of the disk and help verify the correct BIOS settings. However, be aware that the damage to your hard disk may be serious. Sometimes this means that your only solution is to replace your hard disk.

here's what you should do.. first, as mentioned, you should backup all your important files in another drive or an optical drive... once you have done it, format your hard drive and perform scans to check the error.. during scan, you will see errors on it and you may not be able to fix it since the drive is internally damaged.. purchase a new one ok? just make sure to backup all your files..
