Skip to comments.Need computer help from FReeper computer experts (fatal system error c00021a and assorted viruses)
Posted on 10/31/2008 10:12:07 PM PDT by lowbridge
This is a bit lengthy, so please bear with me.
Damn, but I did something stupid and downloaded something I shouldnt have (no, not porn. get your mind out of the gutter :-)). When I downloaded this virus, the cmd screen came up and showed the following: crack.exe, serial.exe, number.exe, keygen.exe AND readme.bat
I panicked, deleted those things, but it hasnt fixed my problem. It seems to have hijacked my internet explorer browser. When I clicked on the IE icon, it brought up the IE browser for all of a second or two before closing. (So, I used Firefox to browse the web, which is working, thankfully) Oh, the IE browser did appear, that is when one of those pop up advertisements comes up. Which I had NO control over. It came up whenever it felt like it, then it stays open untill I close it. BUT I could not use it to browse the web as there are no buttons, tool bar, address box, etc.
And it seemed to prevent me from running/installing spyware. Oh, I was able to download the applications of some spyware programs, but then when I tried to open the application and run them, the damn virus wont let it! I have run a scan with some freeware spy scanning programs and much to my shock they revealed over 250 problems. worse of which are named "spyware.igmonster", zlob, (also spelled out by one scanning program as zlop (with a "p"), trojan.infostealer.bankers
Some spyware programs seemed to be able to download, but when I ran them, they seem to have failed in getting rid of the viruses. (I am using freeware as I do not have any money to buy a good anti virus program) Some seem to do more harm than good as one such program seems to have made me delete some important windows files (a couple of ".exe" files. The spyware program warned me about deleting such a file because it was in my WINDOWS folder, but I chose to delete them anyways as the spyware told me that they were infected) because when I tried to shut down my computer, it gave me a blue screen and an error message (coooo21a). So I had to manually turn it off, but even sometimes that didnt work, so I have to unplug it.
That isnt the end of it.
It was bad enough getting that error message when I tried to shut down my computer, but after another attempted fix of the viruses, it got worse. Now I get that blue screen with the error message when I turn on my computer and try to boot up! I would get a blue screen with the folllowing message;
STOP: c00021a (Fatal System Error) The Windows Logon Process System process terminated unexpectedly with a status of 0x00000000 (0x00000000 0x00000000) The system has been shut down
And the computer wouldnt do anything. It would just sit there with that message staring at me. I would try to shut down the computer by pressing the power button on the tower, but even that wouldnt work! I would have to unplug the computer to get it to shut off!
NOW I'm getting it when I'm trying to start up my computer! I've tried to get around that by starting it in safe mode, but then I just get the above 'fatal error" all over again.
How can I fix this? Can I fix this myself (I'm not computer literate) or do I need the services of a professional (how much do they usuallly charge?)
Just throw it away...
What OS are you using?
windows XP (service pack 3)
Your motherboard is fried.
Sorry for your problems, been there, not fun.
1). reformat the thing.
2). Re-install all software
3). purchase drive imaging software
4). Create image for use the next time you screw your system.
Format the hard drive. Reload XP and start fresh.
How do you know this? And what would it cost for a new motherboard?
When you turn on your computer, hold down the F8 key to get into safe mode. One there, use the system restore to set your computer back to a date prior to your problems. Then reboot and load on some good anti-spyware scrubbing software.
The virus problem is secondary. Trying to deal with this “fatal Error System” has to come first because I cannot do anything with my computer. I boot up, and I get that error message and nothign else. It doesnt go to windows.
The program you downloaded may have come from a cracked version. Like all good hackers...they will place a trojan or several in the serial key generator that comes with cracked software.
How do I reformat the drive? (again I’m computer illiterate)
Your registry files have been altered, so your PC will not boot up likely, but it still should install the freeware to clean out the virus.
They ought to be shot.
I’m no techie but I’ve found that by simply Googling an error code I often get useful advice online. This is what another user was advised on a Yahoo forum:
Do a windows system repair.
Restart the computer with the windows operating disk in the cd rom. When it says “press any keey to boot from cdrom” do so. It will get to a screen that says “ To setup Windows XP now, press ENTER” highlight that option and press enter.
It will ask you to accept the license agreement by pressing F8. Do so and then it will list your o/s choices that already exist on the computer. Highlight your windows installation and then press the “R” key.
Then let windows do its thing. It will look like it is doing everything from scratch, but it is just repairing the system. Make sure you have your license key because during the setup it will ask for it. The system will reboot 1 or 2 times during the process. When all is done you should have everything you started with file wise and hopefullty your stop error will be corrected.
How to boot from cd rom:
Try post # 10. And when you run your whatever flavor of antivirus, update your definitions at least once a day. I run AVG, and haven’t been bugged in 10+ years. Yeah I do visit goofball sites as well.
Spyware and anti-virus programs are junk. They will create more problems than they prevent. I run a 7 node wireless N home network behind simple encryption using Comcast for 8 years now. With 2 little kids who are computer literate. I've never had a problem.
No, seriously, you have Malware. You need to wipe or Fdisk your system and reinstall everything. Your BIOS are fine. So, Wipe it, install it and stop stealing software.
“When you turn on your computer, hold down the F8 key to get into safe mode.”
Cant. I’ve tried to do what you suggest, BUT after getting into safe mode, I STILL get that “Fatal system error” message.
I press on F8, it gives me those several options of starting normal windows, safe mode, etc. I choose safe mode, it goes to the blue screren with the error message.
At this point, I think I would consider whether or not there was anything on your hard drive that you couldn't live without. If not, reformat the drive and reinstall everything from scratch.
If there are files you need to get off, you have some options. You could take it to a repair shop. They deal with this stuff all the time. If it was my computer I would get a new hard drive, install Windows XP on it along with a good anti virus package. Then, I'd install the old hard drive in the machine and do virus/malware scans to clean it up before getting the files off of it. Lastly I would reformat the original hard drive to ensure all the nasties are gone.
Stick the XP OS disk in and follow directions.
I had the same problem many years ago. I went to a website that offered a game I wanted, cracked. The minute I installed it, all hell broke loose. I didn’t know much about how to fix hijacked hard rives and registries, so I wiped the hardrive and reinstalled XP. Now, I could have fixed it.
I too ran into some trouble the other day on a computer that isn’t usually online. I highly recommend a program called ESET Smart Security. I found this to be much better than some of the “top” names. Had me back to normal in a few minutes. Good luck.
“Page Not Found”
Try fixing the problem suggested here before you wipe though. It could be just a virus problem. Do you have recovery disks?
You’ll need to do a full system recovery then. (booting from recovery disk)
If you want any files, use a a Knoppix to get it off to a USB Stick
Don’t try to start it up anymore
You are only making it worse.
oops, sorry, looks like I managed to cut off the end of the link. Try this:
There's nothing really important that I couldnt live without. But how can I "reformat" (and how does one reformat), when I turn on my computer and get nothing but that error screen? I press on alot of buttons on my keyboard, and it just doesnt budge. How can I get anything done, like a reformat, when the computer just wont respond, wont come out of that error?
I dont. M computer didnt come with them. (At least that I can recall). My brother on hte other hand has a windows xp service pack 2 reinstallation disc.
Can you boot from the Operating System CD?
There’s a way to change the drive order that your system looks at as it boots up. Your main hard drive will usually be drive C: & your set up will usually look on C: by default. As you boot up, there will be a screen that tells you to hit F2 to go to setup. You can change to your computer looking for your CD drive letter first.
If you can get your computer to boot from your CD, you can overwrite your operating system files & that might let you get back to booting normally again.
Does your brother’s computer use the same OS as the one you have on your machine?
Yes, were both windows xp. Though my “service pack” is number 3, his is number 2.
That might work. As long as it’s not an upgradeer.
Buy another computer. Seriously.
It may not work with different versions, but it’s worth a try. You won’t be able to install Windows using his CD, because the license won’t work. However, we want to see if we can get past that blue screen, fatal error.
Did you try to start it with your brother’s CD in, after changing boot drive order like I told you to do?
P.S. Only install only ONE anti virus software because if you have two, one will suspect the other.
Dont have the money to buy a new one. I need to do whatever I can to save this one.
stick your XP cd in the drive and set the bios to boot off the drive.
Fair warning: you’re gonna lose everything you had on the disk but at least you’ll have a clean install.
Folks that suggest you use AV to clean it now mean well, but it’s always been best to just clobber the thing, reinstall all software, install AV, and install imaging. Build the image and the next time you goof, just rebuild from the image. It’ll be just like you left it.
“Did you try to start it with your brothers CD in, after changing boot drive order like I told you to do?”
Havent gotten started yet. Its way too late. I’m trying to drink in all this technical info and advice before I can do anything :-)
Trend does have a good online virus scan, but he won’t be able to get to the net until after he’s gotten it running on Windows.
I dont mind losing everything. I had nothing important on my computer. nothing which I couldnt get back anyways. But what is “AV” and “imaging”?
Had the same problem.Took mine to a repair shop and got reformated for less than 40 bucks.They also loaded a lot of free anti virus stuff.
You should have your own set of CD’s for your OS. If your computer came without them, contact the manufacturer of your computer & ask them to send you some.
Buy one at a garage sale or salvation army or watch during trash pickup day. I just threw out about 15 dell optiplexes last week.
