    whenever i turn my computer on, it loads as normal, but after it has loaded microsoft windows (the page with the scrolling bar) and the blue XP screen comes up, the different usernames do not come up. instead when it says "windows is loading..." the whole thing restarts and does it again.

    sometimes it comes up with the setup screen (without me pressing delete) but i dont kno what is wrong!!

    Please help,
    Thank You,
    Rich T.

    Enter into Safe Mode on BIOS check screen by tapping the F8 button. Make sure you have a keyboard that has PS/2 connection or USB legacy enabled in BIOS.

    Once in Safe Mode try and run any anti spyware programs or ant virus programs you might have. Some infections reboot the computer.

    Did this problem just start happening or has it been doing this for a while?

    Also, if you have a XP boot disk try using a System Restore Point to see if the problem is fixed that way.

    If all these fixes don't work try repairing Windows with an XP disk.

    SFC /scannow tutorial;
    Scan For Missing/Corrupt System Files...

    Windows XP comes with a wonderful tool called System File Checker (SFC)
    Itscans and verifies the versions of all protected system files after you restart your computer...
    To Do This:
    Click Start menu, and then click the Run icon.
    In the small box that Opens, type the three letters: cmd then click the OK button.
    In the command prompt window that just opened (a black background and white text), type the following command:
    SFC /scannow
    And then click OK
    You must be logged on as a member of the Administrators group to run SFC..
    You will need your Windows XP CD during this procedure if SFC needs to get an original file. Please remember that Windows XP can have multiple instances of a .DLL file and remember which version is for which program.
    Notes....
    I have been asked if it is possible to have a "progress meter" show when SFC runs... This is the registry hack you need. PLEASE do not go messing with your registry if you do NOT know what you are doing!
    System Key: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
    Value Name: SFCShowProgress
    Data Type: REG_DWORD (DWORD Value)
    Value Data: (0 = disabled, 1 = enabled)


    MORE INFORMATION from Microsoft Corporation;
    http://support.microsoft.com/kb/310747

    System File Checker gives an administrator the ability 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 of the file from the cache folder (%Systemroot%\System32\Dllcache) or the Windows installation source files, and then replaces the incorrect file. System File Checker also checks and repopulates the cache folder. You must be logged on as an administrator or as 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, the sfc /scanonce, or the sfc /scanboot commands to repair its contents.

    System File Checker Tool Syntax
    Sfc [/Scannow] [/Scanonce] [/Scanboot] [/Revert] [/Purgecache] [/Cachesize=x]
    • /Scannow: Scans all protected system files immediately and replaces incorrect versions with correct Microsoft versions. This command may require access to the Windows installation source files.
    • /Scanonce: Scans all protected system files one time when you restart your computer. This command may require access to the Windows installation source files when you restart the computer. The SfcScan DWORD value is set to 2 in the following registry key when you run this command:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
    • /Scanboot: Scans all protected system files every time you start your computer. This command may require access to the Windows installation source files every time you start your computer. The SfcScan DWORD value is set to 1 in the following registry key when you run this command:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
    • /Revert: Returns scan to the default setting (do not scan protected files when you start the 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 the Windows installation source files.
    • /Cachesize=x: Sets the file cache size to x megabytes (MB). The default size of the cache is 50 MB. This command requires you to restart the computer, and then run the /purgecache command to adjust the size of the on-disk cache. This command sets the SfcQuota DWORD value to x in the following registry key:

    Welcome to TSG!

    SFC, Spyware and Antivirus scans are all good ideas.

    But also do the following so we can get a better idea of why the system is doing this.

    Tap F8 when the PC starts, but instead of Safe Mode select Disable automatic restart on system failure on the Windows Advanced Options Menu. That's not always an option on all systems though. If not, boot to safe mode, and disable the automatic reboot like this:
    Right click My Computer, click Properties
    Click the Advanced tab
    Under Startup and Recovery click the Settings... button
    Under System Failure uncheck Automatically restart
    Ok back to the desktop, and then reboot. This will let the system stop so you can see the error

    Post the complete error message here.

    May be time to check the internal connections.
    Turn the computer off and disconnect it from the power
    Take off the side of the case and touch the bare metal chassis to discharge static.
    Remove Ram..Video cards from their slots

    Plug in the RAM [one stick at a time].
    Also try different slots.
    Ensure it is seated correctly.
    Reseat Video card.

    Check Hard drive and Motherboard connections [IDE]
    Take them off and reseat them.

    Inspect the case for dust etc.
    Remove the dust..do not use a vacuum cleaner

    Check that the processor fan rotate. Check for dust.

    Turn on and listen for a beep.

    A properly working computer should beep once while booting, and the lights on the keyboard should flash while booting.

    @ Mega Tron... its a recent thing .. .never happened before. my comp is bad but its never been like this.

    finished scanning almost 1,000,000 files and it came up with 5 things:

    Adware:win32/exact.G - alert level High
    Program:win32/PwerRegScheluder - alert level Medium
    Spyware:win32/2Search - alert level High
    Spyware:win32/180SolutionsWebInstaller - alert level Medium
    Trojan:JS/Agent.FA - alert level High

    will delete these 5 now and see what happens....


    Deleted all 5 and upon rebooting my computer it did the same thing yet again... i guess its not caused by a virus...

    time 2 try a 3rd theory

    Thanks anyway... thts 5 viruses gone from my comp =)

    Those infections are worse than you think in my small little experience.
    I would bet you are still infested with malware. and that they may not in fact be gone yet.
    You can start by reading the sticky posts here;
    http://forums.techguy.org/54-malware-removal-hijackthis-logs/
    and go from there.
    Just a thought after you are all done with this, you may want to backup all your personal files to CD-DVD and try a system repair or restore and get your system running fresh again you have a million files on your system thats quite a few and your system is probably running a lot slower than it could.

    If setting the Disable automatic restart on system failure setting didn't get you to a nice Blue Screen Error, it's sure sounding like malware.

    Double check the settings to make sure they "stuck" though.

    If they did, if you can boot to safe mode, choose Safe mode with Networking, that should let you get on line so you can download HJT, or you can download HJT on another PC and copy it over using a Floppy - USB flash/external drive - CD, it's only 793 KiB in size.

    Go to Download HiJack This

    • Click the Download HijackThis Installer link.
    • Save HJTInstall.exe to your desktop.
    • Double click on the HJTInstall.exe icon on your desktop.
    • By default it will install to C:\Program Files\Trend Micro\HijackThis
    • Click Install
    • Click the I Accept button on the License Agreement Window
    • The Main Menu window will open
    • Click on the Do a system scan and save a log file button.
    • It will scan, save the log in C:\Program Files\Trend Micro\HijackThis, and then the log will open in Notepad.
    • In Notepad, click on Edit > Select All then click on Edit > Copy to copy the entire log.
    • Paste the log in your next reply.
    • Paste the entire log into the reply window below your description of the problem.
    • DO NOT have HijackThis fix anything yet. Most of what it finds is required or harmless.

    Give as much information about the problem as you can.
