My computer is in serious trouble and I hope someone here can help me! My computer is in a continuous loop of rebooting itself when it is trying to start up Windows. I cannot get it to Safeboot, last known good configuration or anything like that. I do have the Recovery Console but I don't know how to use it. Right before this started my AVG popped up that I had a virus. My computer did a reboot on its own and it hasn't started Windows since. I have gotten this when I disabled the auto restart: STOP c000021a it terminated unexpectedly with a status of 0xc0000034 (0x00000000 0x0000000) The system has been shut down. Please let me know what I need to do to get this fixed hopefully! This is a Gateway that is about 4 years old. Thanks for the help!

Hi,

That stop error sounds like inaccessible boot device, which could be possible if a virus did wipe the boot record from the drive. Also make sure that you do indeed have Windows XP Recovery Console (in my experience, some users get the Recovery Console and System Recovery options mixed up). Recovery Console is very crippled version of a Windows command prompt and System Recovery (when it actually works) restores your system to what it was when it came from the factory (usually nowadays by re-writing the operating system partition from the hidden system recovery partition).

Anyways, we want the first option, it should load and ask you to select which Windows to load, if you have only one OS, it should be the only one listed so you would select 1, you should now be asked for the system's administrator account's password (This is the password for the built in Administrator account), if it has not been set, press enter as it is usually blank anyway, if you do know the password, enter it in. If your successful, you will end up at a command prompt at the prompt type the following:

fixmbr [hit enter key]

chkdsk /r [hit enter key]

exit [hit enter key]

the system should reboot and hopefully it will work fine.

Note: if you can't get into recovery console (unknown password??) I do have a special DOS boot CD that will allow you to run the Windows chkdsk from regular DOS. It can be found on my site (see signature) and search for 'special boot cd'.

I won't post a direct link to it as that would likely be considered redundant.


Hopefully that will work for you.

Hi Jeffrey! I did all of the steps above. It said that it found and fixed one or more errors. But when it restarted it is just going back into the loop again. Same system error and everything. Is there something that I am missing? or something else I should try? Thanks for the quick reply!

You could try a Repair install of Windows. Insert Windows CD. Reboot computer. Allow the computer to boot to Windows CD. When prompted choose "Install Windows" at the first opportunity. Then at the second opportunity choose "REPAIR" (which is hitting the R key). Then let windows do a repair install. Theoretically this will not affect your data or programs, but I suggest making full backups first anyway, as backups are never a bad idea.

Also please note: Not all versions of Windows install CDs have the option for a Repair install. Let us know if that is true in your case.

NOTE: Choosing 'R' at the first opportunity will give you the Recovery Console and this is NOT what you want. You want to choose 'R' at the second opportunity.

Here's a link to a description of the STOP error: http://aumha.org/a/stop.php#0x21a
As you can see, it's an error that involves security of the system.
Most commonly these are caused by viruses - although I've seen them occasionally with a Windows Update on top of outdated drivers.

The status code that ends in 34 means that the object wasn't found. This is what the program was looking for when the crash occurred.

Since you're not able to get into Windows, the best thing to do would be to slave the hard drive to another system and scan it for viruses there. If it's infected we'll have to take other steps.

If it's not infected, then a repair install is the best option at this point.

Thanks for the advice everyone! I have an older computer that I am on right now but it only has Windows 98. Would it be possible to hook the Gateway computer to this one? Is there a chance I could get my stuff off of the Gateway computer this way? I made "rescue disks" when I first bought the Gateway so is that what I would use to do the repair install? How do I make backups of my system if I can't get in to Windows? Is there a way to do this? Thanks so much!

Missy
