Emachines T4010 won't start up, says image checksum, and that an image is corrupted


Receiving a bad image checksum error message when upgrading a computer to Windows XP means that a Windows system file such as user32.dll is damaged. This error occurs when any damaged system file is encountered that isn't overwritten during Setup. The repair process for this error involves voiding the damaged dynamic link library file from the DOS command line prompt and replacing it with a new copy from the Windows XP disk.

Insert a clean Microsoft Windows Millennium Edition (ME) or Microsoft Windows 98 Edition startup disk into the computer, and hold the reset button on the front of the computer until the system commences rebooting. Navigate the Windows startup menu with the keyboard's directional keys and select 'Start Computer with CD-ROM Support'. Hit "Enter" to continue. Write down your CD-ROM's drive letter on a piece of paper. At the command prompt, type "Drive:" without quotes (Drive should be replaced with the drive letter on which Windows is installed), and press "Enter." Type "cd windows\system32" without quotes, and press "Enter." Type "ren user32.dll user32.old" without quotes and again press "Enter." This renames your damaged user32.dll file so it is not recognized by the system, but still physically exists as a backup if needed in the future. Eject the Windows ME or 98 disk, and insert the Windows XP disk. At the command prompt, type "extract CDROMDrive:\i386\user32.dl_ Drive:\windows\system32\user32.dll" without quotes, replacing CDROMDrive with the CD-ROM's drive letter that you made a note of earlier, and replacing Drive with the system's drive letter on which Windows is installed. Hit "Enter" to execute the command. This process extracts a new copy of the user32.dll file to your hard disk, from the Windows XP CD. The new file will be found in the Windows/System32 directory. Restart the system by holding the reset button on the front of the tower until reboot commences.

Unregistering DLLs


<p><b>Introduction:</b><br /> <p><b>What are DLL files?</b><br /> <p>DLLs are dynamically linked library files. DLL file contains a list of certain functions that can be used by various applications. Spool32.dll is a great example of how the things work: that file is used by various programs for print control within Windows 95 and Windows 98.<br /> <p><b>Why is it important to unregister malicious DLLs?</b><br /> <p>DLLs may contain information essential for a computer to function properly. Malicious programs may corrupt regular DLL files or they may install new DLLs instead of normal ones.<br /> <p>Deleting DLLs is a risky deal since it can affect computers performance and functionality of many applications. If a malicious DLL is somehow used by a regular application and the DLL file is removed, the application won't work normally even if the deleted DLL is not needed for a program to function. This is why you have to unregister DLLs before deleting them.<br /> <p><b>How to unregister malicious DLL files?</b><br /> <p><b>a) Open Command Prompt window</b><br />Click the "<b>Start</b>" button and select "<b>Run</b>" option. Type "<b>cmd</b>" into the "<b>Open</b>" field and click the "<b>OK</b>" button.<br /> <p><b>b) Unregister malicious DLL file<br /></b>Type "<b>regsvr32 /u filename.dll</b>" into the Comand Prompt window and click "<b>Enter</b>". "<b>Filename.dll</b>" should be the name of DLL file you want to unregister<br /> <p>

When trying to reinstall windows xp, the process keeps failing during setup saying, "The file comct132.dll was not copied correctly. The file Setup on your hard drive is not a valid Windows XP system...


Click start/run Type: cmd
In the Command window type:
SFC /scannow Note the space between SFC and /scannow

You can copy/paste: SFC /scannow

Hit the Enter button
keep your xp cd handy in case you're asked to chuck it into your cd rom

The above should replace missing files and get you to the place where the install can proceed.

Let me know. __________________

Got a virus - cleaned it out- computer would then only connect to internet in safe mode with networking but now won't connect at all


hi, try this

The suspicion of possible errors in system files in Windows, it may be worth a try to run the "hidden" program that comes with just Windows.
System allows an administrator to scan all protected files to verify their versions.

If System File Checker discovers that a protected file has been overwritten, it retrieves the correct version from the cache folder (% Systemroot% \ System32 \ Dllcache) or source files for Windows installation, and replaces the incorrect file.

System File Checker also checks and filling up the cache folder. You must be logged on as an administrator or a member of the Administrators group to run System File Checker.

If the cache folder becomes damaged or unusable, you can use the sfc / scannow, sfc / Scanonce or sfc / scan boot to repair its contents.

To use SFC:

1) Press Start
2) Select Run ...
3) Enter: sfc / scannow and press OK
(Remember that there should be space after sfc)



More info about the System
Sfc [/ Scannow] [/ Scanonce] [/ Scan Boot] [/ Revert] [/ Purgecache] [/ Cache Size = x]

• / Scannow: Scans all protected system files immediately and replaces incorrect versions with correct Microsoft versions. This command may require access to source files for Windows installation.

• / Scanonce: Scans all protected system files once when you start the computer. This command may require access to source files for Windows installation when you start the computer. SfcScan DWORD value 2 in the following registry key when you run this command:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon

• / Boot Scan: Scans all protected system files every time you start your computer. This command may require access to source files for Windows installation every time you start your computer. SfcScan DWORD value of 1 in the following registry key when you run this command:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon

• / Revert: Restoring default scan setting (not scan protected files when you start your computer). The default cache size is not reset when you run this command. This command is equivalent to the / Enable switch in Windows 2000.

• / Purgecache: Purges the file cache and scans all protected system files immediately. This command may require access to source files for Windows installation.

• / Cache Size = x: Sets the file cache size to x megabytes (MB). Default cache size is 50 MB. This command requires that you restart the computer, and then run the command / purgecache to adjust the size of the cache on the disk. This command provides SfcQuota DWORD value of x in the following registry key:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon

Run Commands


Do you use the Run feature in Windows?

Many computer users, don't even know that, there exist hundreds of commands, which can enhance your experience using computers..... and they are even useful to impress others with your knowledge in computers.

Nearly all of the Run Commands Correspond to a particular Control Panel Item or any utility or tool or task that can be accessed through Windows.

There are, however, tools and utilities that I bet you never knew you had that can be accessed through the Run feature.

I cannot start-up a Dell Optiplex GX260 in normal mode


I recently had a problem that sounds similar to this - A virus was causing a fake validation window to pop up when I booted my computer and blocked all other functions. 
Start your computer in Safe Mode and go to Start>Run>type msconfig and hit ok. Go to the Startup tab, make sure you can see everything in the Command column, and uncheck anything that doesn't sound fimilar. Hit ok then restart and see if the validation window pops up again after a normal boot. If it goes away you can prpbably clean away the rest of the virus with a simple virus/adware scan.

Do not know how to install software


How to install a software program can depend on the operating system being used and the program being installed. Because of all the different possibilities, we have created the below steps as guidelines for installing programs in each of the major operating systems.
Notice: This document has been created as a basic overview on how to install software programs, games, and utilities on your computer. If errors are encountered during the installation, this document will not cover those errors.
General Tips
Microsoft Windows 95, 98, NT, ME, 2000, and XP users
MS-DOS Users
General Tips
  • Make sure your computer meets the requirements of the program, game, or utility you are attempting to install.
  • The manuals for the program or the readme file located in the same directory as the install commonly contain exact instructions on how to install a program.
  • After installing or during the installation, a program may need to install other programs, files, or utilities before it is able to run. If this is the case, the program will commonly prompt you to install the program or you may need to run a separate install before the program can be fully used.
  • When installing a program, utility, or game, it is always a good idea first to close or disable any other programs that are running.
  • After installing a new program if it prompts you to reboot the computer, do it.
Microsoft Windows 95, 98, NT, ME, 2000, and XP users Many software programs, games, and utilities have an AutoPlay feature that will automatically start the setup screen for the software program when the CD is placed in the computer. If your program, game, or utility contains this feature, run the installation through the screen that appears after inserting the disc.
If you are installing a program, game, or utility that does not contain this feature or you are installing a program from a floppy diskette, follow the below steps.
  1. Open My Computer.
  2. Within the My Computer window, open the drive that contains the installation files. For example, if the files are on a floppy diskette, open the A: drive. If they're on a CD or DVD open the D: drive or the letter of the disc drive.
  3. Within the drive that contains your files, locate either a setup or install file. Double-clicking on this file should start the installation for the program, game, or utility. If you see multiple setups or install files, try to locate the Application file or double-click each of setup or install files until you find the file that starts the installation. Many times the icons associated with the installation files have the same name.
An alternate method of starting the installation in Microsoft Windows
  1. Click Start and Run.
  2. In the Run Window, type x:\setup or x:\install where x is the letter of the drive you wish to start the installation from. For example, if you are attempting to install a program from the floppy disk drive you would type a:\setup or a:\install.
MS-DOS Users Users installing a program from Microsoft DOS should have a basic understanding of the MS-DOS commands. If you are unfamiliar with any of the commands listed below, click the link to get additional information and examples on the commands.
  1. Before installing a program in MS-DOS, you must switch to the drive and/or directory that contains the installation files. If you are installing a program from a CD or diskette, switch to that drive. Additional information about switching drives in Microsoft DOS can be found on document CH000515. If the installation files are located in a different directory, use the dir command to list the directories and the cd command to switch into the appropriate directory.
  2. Once you are in the directory or drive that contains the installation files, run the executable for the setup. Many times this can be done by typing setup or install at the prompt to start the installation. If both of these commands give a bad command or file name error message, type dir *.exe or dir *.com or dir *.bat. These commands will list any executable files; if any files are listed, attempt to execute these files to run the installation or setup of the program. If no files are listed when typing all three of the above commands, it is possible that either you are in the incorrect directory or drive letter, or that the program.
Additional information about running an file from MS-DOS can also be found on document CH000598.
Additional information:
  • Information about problems that can occur after an install can be found on document CH000123.
  • See document CH000506 for information about how to extract a file that you've downloaded before installing a program.

Turn on computer- Wont boot Please Help!!!


Borrow an XP install disk from anyone. Since you are not installing a new copy you don't need a keycode or serial number.

I am willing to bet however that you are going to need to do a re-install having lost this file to corruption. The source of the corruption is the unseen elephant in the room. Be aware that if you can get the computer running move any personal files to new new folder on the C drive. One that you create and not in 'My Documents' or any other windows created folder. When re-installing windows any/all windows folders are deleted and new, empty ones are created resulting in your loss of everything.

1. Boot the laptop;
2. press F12 to go to boot menu;
3. Selected CD/DVD-RW Drive;
4. Press any key to boot to CD; worked fine...
5. Press R to repair;
6. At the recovery console, selected 1: C:\WINDOWS and hit enter;
7. This brought me to C:\WINDOWS> prompt;
8. Typed this C:\WINDOWS> EXPAND -R D:\I386\c_437.nl_ C:\WINDOWS\system32\c_437.nls

type exit

9. And got the error message: The parameter is not valid. Try /? for help.

IF the disk is in the D drive then use this command instead: expand d:\i386\c_437.nl_ c:\windows\system32\
