Default Error code 161 - 0xa1

I have a Dell XPS 420 desktop computer with Windows Vista 32 as its operating system. I began experiencing issues with my pixels scrambling and (ATI 2600) game card crashes after an automatic ATI/AMD update. I also have Kaspersky anti-virus software on my computer. The two had driver conflicts after the update. My game card eventually failed completely after numerous crashes and computer shut-downs. I was advised to run Combo-Fix (with detailed instructions) and during the process of Combo-Fix running, the computer crashed and came back up with a black screen with a white cursor. I cannot access my cd/dvd drive, internet, safe mode, etc. The only thing I can do is go through the F8 feature. Restore points are gone. Last good configuration does nothing. I need to uninstall the old drivers from my ATI/AMD graphics card and install a new GEForce game card, but I don't know how to do it through the command prompt. I downloaded DriveSweeper, DriverDetective, DriverFusion, but I received errors on all of them and they would not install. There are tax files and other files as well as passwords on the computer that I cannot afford to lose. I don't want to reinstall windows if at all possible. Any suggestions? I desperately need help as soon as possible. I am at a complete standstill until I can uninstall the old drivers and install the new ones.

If you have access to another machine you can try downloading a version of Linux such as Ubuntu or Linux Mint, burning it to a DVD and then booting into a live session. You should then be able to access your Windows files and save these to a pendrive.

Another alternative would be the tool provided by AVG which is also Linux based and a much smaller download.

IMO re-installing Windows after this will be the only viable option as the original problems, compounded by the use of Combo-Fix, make it unlikely the system can be recovered to a usable state.

I didn't mention that I converted the Windows Vista repair disk to an ISO file on my flash drive and ran it on the computer. It corrected all errors except the 161. It shows a hardware failure. I know that it is because I could not remove the old drivers from the ATI 2600 card and install the new GEForce drivers for the new card. The computer diagnostics also shows a hardware failure. My problem is how to uninstall the old drivers and install the new drivers via command prompt.

This is an operation I've never performed so can't advise from experience. I did however find these which may help you.

That's what happens when you follow a bad advice. ComboFix is a very strong tool, and is used when you have malware on the system, and that too in situations, where the infection is quite strong, and not removed by normal means.

I don't understand the use of ComboFix here, when there is a driver issue. Clearly, running such a tool involves risks, and that's what happened... you now got an unbootable computer.

Really bad piece of advice. Who gave you this?

What's this feature supposed to do?

Why did you download all these software? What were they supposed to do?

You said they would not install. That means the computer is bootable? Please explain as it's not clear.

From what you wrote in your post, it seems that the computer is not bootable at all. But from what you write about the software, it appears that the computer is bootable, and you were not able to install these software. What's the exact situation?

How did you run computer diagnostics? Which hardware is showing failure?

If it's clearly showing the ATI card as failure, simply take that card out from the computer.. if it's a separate card and not inbuilt into the motherboard, and then try booting the computer.

Unless the computer is able to boot, there is no way you can uninstall the drivers.

Please answer the queries that have been put forward, and then we can advise something, as many things are still not clear.

I believe the tech was trying to eliminate the possibility of any other problems. I will say that he gave very detailed instructions on what to do and what not to do. I will try to be a little clearer in my descriptions. I downloaded the software out of simple desperation. I googled my issue and was directed to several different sites, and I tried most of the suggestions (right or wrong). When I turn my on computer, it comes up to PNY GeFprce 21- PCIe 2.0 Version 70.18.5F.00.00 screen , Dell welcome screen and appears to load windows, then it goes to Intel Matrix Storage Manager option ROM v7.6 screen, then it goes into a loop of the same process. The F8 takes me to the repair options. I tried the Automated repair, Restore (no restore points), Last good configuration (none), Safe Mode, Safe Mode with Networking, Safe Mode with command prompt (same results as when I start out of safe mode), and finally Go to command prompt (which I can do.) If I hit F10 when I start the computer, I can run diagnostics on the computer. F2 I can go into setup. Those are the options available to me. My DVD/CD drive shows a spindle error when I try to change the boot sequence to that drive. I can use a flash drive to install or view files or to boot up from the repair disk. I converted the repair disk to an iso bootable file on the flash drive. I did remove the ATI card from the computer. The GEForce card needs to be installed. The installation is on a disc and I have not been able to install it from the flash drive. I googled changing the cards and it said that the old drivers have to be removed before installing the new ones. I am sure you can tell that I am a novice at this, but I follow instructions well and am willing to learn. Please tell me if I am not clear and I will do my best to clarify it. I may not know the correct terminology, but I will do my best to make you understand. Thanks for your patience with me.

Well, I can surely say that even if the tech gave you detailed instructions, they were for the wrong thing.. and ComboFix should not have been run on the computer, as there was no need. It must have deleted some important system files, or something, because of which the computer is not able to boot properly.

All you had to do was uninstall the driver for the ATI card from Device Manager. It was as simple as that.. since you already knew that the updated drivers were the problem.

Anyways.. can you please tell the model number of your computer?

Also, GEForce is a separate graphics card which you are trying to install? If yes, then I will advise not to do that, and take it out for the time being. Try to boot the system without that card. See if the system boots then.

During booting, or during the boot loop process, are there any error messages, or any other messages that are being shown? Like any messages on the Intel Storage Manager screen?

If your CD/DVD drive is damaged, you can consider buying a new one. They come very cheap nowadays... so, I will advise you to change it. If you can do it on your own, fine, otherwise, please take the help of a technician rather than doing things yourselves.

If you are not able to supply more information, which will help in solving the problem... I will suggest that you get the help of a good technician.. call one at your home, or take the computer to a good tech shop. It's better to get help and spend some money, rather than messing around in the system yourself, which can cause more problem, as you can see.

I agree with your comments on ComboFix, but it I can't undo what has already happened. My computer is a Dell XPS 420. The GEForce is the replacement graphics card which I am trying to install. I will try booting without it and get back with you. There are no other error codes during the look, but I received the following problem signature code 6.0.6000.16386.0.0.0 after running the repair disk.

Well, I am unable to provide any more help, as it's beyond me I suppose. You can wait for anyone else to offer their help here, or, you can try other forums like www.techguy.org.

If not, then you can take the computer to a shop, and get tech help.

Sorry for being unable to provide anything helpful.
