Ok, long story short, I just had this nice topic all typed up, explaining in detail what I've run into in a friends computer, and the last thing that I typed in was that great big long number that accompanies the BSOD, then the wife wanted to use the computer and closed the window that I had left open with the post in it......this is why I don't take her nice places :thumbsup:

Anyway, per the topic title and description, that's what I'm running into. It loads me directly into the screen where it apologizes for not doing something (starting up or shutting down) correctly, and offers me a few choices as to how to load into windows....safe mode, safe mode with command prompt, last known good configuration, start windows normally (might be another one or two, I can't remember, although they were all listed in my other post that I worked on for 30 stinkin' minutes!).

I went into the bios, and reset it to default-->no help. Here's what I tried/checked thus far: Checked all connnections, inside and outside of the computer...all fine. Checked all fans...all working fine. Tried booting into every option available, then it takes me right to the BSOD no matter what option I choose.

After interrogating the parents and kids (that the computer belongs to), I found out that even though I had set up the machine less than a year ago with 2 accounts, one for the kids and one for the parents, with the kids account having no permssions to install anything or make changes to the OS, and the parents with full admin rights....the silly dad gave the password to the eldest child so he could download music via limewire....less than a week later they had the pleasure of viewing the BSOD. Lucky them....even luckier me :flowers:

I can see the POST screen, and get into the bios and attempt to do a system recover, but the system recovery leads me to the BSOD, and reseting the

So, I'm thinking that it's either a hardware failure that I can't see (maybe hdd?) or they picked up a virus and I'll need to wipe the drive and reinstall the OS (OS=WinXP). I'll post the important lingo from the BSOD below.

UNMOUNTABLE_BOOT_VOLUME

***STOP: 0x00000ED, 0x80EBEBB8, 0xC0000006, 0x00000000, 0x00000000)


So, any and all help I can get with this would be greatly appreciated. I tried to google this, but came up with about a billion pages, none of which I found anything that helped me (ok, ok, ok, so I didn't read all 1 billion pages).

I'm thinking you're correct on the Limewire issue.

If possible, do this 1st:
a. Plug the hard drive into another computer as a SLAVE, and run a virus scan on it. As a matter of fact, run a few different virus scans, And when I say the word virus scan, I personally mean Adware, Spyware and the Virus Scans. All 3 types. Run each of them. Even if you need to run more than one type of scan of each virus category.
Example... you may need to run more than 1 virus scan software, more than 1 Adware software, etc...

b. If the BSOD doesn't subside, and section acomes up clean, what I would do is, backup the hard drive, repartition it, then reformat it and reinstall the OS again. Then reinstall the programs, but MANUALLY transfer each bit of data back to the drive again. and...... scan it again.


[Note] Repartition the hard drive 1st, then format it 1st if you have to b.

I believe the viruses, worms and trojans, etc war is getting to the point of all out war on computer users, especially torrent and peer-2-peer.

All you can do is monitor what your computer (installs), and have a backup plan just in case it decides to go south on you.

If I install it as a slave, won't the virus jump to my computer's master hdd?

That depends on the software you use. [EDIT] It's possible.

when you run virus scan and the like, they automatically scan the operating OS system files, memory and such, so that way, if it detects something, it'll know it's in the memory or such. But if you set it to scan a particular drive (no matter how many drives you have installed), they will just scan the memory and certain areas of the operating OS, and then scan what drive you assigned it to scan.

Before I start pulling it all apart (not that removing a hdd is all that difficult), I'd like to rule out that it might be a stick of bad ram.

I don't think that it is because WinXP actually starts to load...it gets to the "Windows XP" screen where the blue squares kind of scroll from left to right across the bottom of the screen just below the logo like it's actually going to start windows, then after maybe 2-4 seconds, it goes right to the BSOD. If the ram was bad, I don't think it would make it this far, would it? I'm not sure exactly when the computer checks (or knows) if the ram is faulty or not.

If it's not the ram, then I'm sure it's the file system that's been damaged, and will need to be repaired....but I can't even get into safe mode with commandprompt to run checkdisk on it...so I'll most likely end up reinstalling windows if the ram isn't the problem.

I don't have any 2700 lying around the house, but a friend has some that I can kidnap tomorrow night to swap out this stick on the comp with the BSOD (it's only got 1 stick of 256mb).

Can anyone confirm what I'm thinking about for the ram?

The computer will check the ram during the POST. But even if it loads correctly, that still doesn't mean the ram is ok. Chances are, if it does load past the POST, then it found no problems.

You can take out the ram, and try to reseat them. It may fix the problem.

If that doesn't work, you can take out the battery on your motherboard, let it sit for about 30 minutes, then put it back in, and boot up.

If the above doesn't work, then you'll need to plug the hd to another one and do a scan on it. If they come up clean, then it may be time to reformat the hd. There's no telling what those kids walked into and don't know it.

Sometimes the only thing to do when computers get to a point of unbearable actions is to simply back up the data, wipe out the hd, and reinstall everything. It does happen. I just done one of mine yesterday. After years of it running.

I know you hate to do it, but sometimes there aren't too many other choices left.

If you are certain that there is no media in the floppy or disk in the cd, and the hard drive is listed in the boot order, the hard drive may be bad.

Look in the bios to see if the hd is being recognized.

I would then remove the hd, install it as a slave on another computer and begin scanning. Adware will not cause that particular problem, although that is not saying that the drive is not infested with it.
I would be more concerned with viruses at this point.

Run some of the following on-line scans using Internet Explorer only:

and

Ewido Online scan

Windows Security Trojanscan

Parasite scan from Aumha:

or here:

See what you find.

OR

If you are planning to format and do a full install you can skip all the above.
Just use a program that will overwrite the drive completely, like Killdisk so there is no chance of any virus surviving.

After doing that go to the bios and set the boot order for cd first, then do a full installation of Windows.

There is a free memory tester available here: http://www.memtest86.com/

Just follow the directions and let it run for at least 2 hours (overnight is better). Errors generally indicate bad RAM.

Also, most hard drive manufacturer's offer a free, bootable tool for checking their hard drives. Try downloading that to check the status of the hard drive.

Well, I swapped out the ram with a different stick of the same speed/size and it made no difference. I gave the ram that I pulled from the computer with the BSOD to a friend to put in his computer and it was recognized no problem by windows. This sorta convinced me that it was a virus from one of the kids downloading things from P2P networks. Rather than wasting more time (and their money) on pulling their hdd and scanning the crap out of it, I just wiped the OS with Killdisc then reinstalled the OS on it. I'm setting up the admin and user accounts now and will be updating it and installing the drivers for everything so I can get it back to them.

Thanks for all the links Enthusiast. If I wasn't charging them, then I'd take my time and do the scans to find out exactly what the issue was. Of course, I'd like to know that since the system files were corrupt, if removing the virus through a scan would allow the machine to boot normally (would it?). They also said that there wasn't anything on the machine that they needed...they just use it for internet browsing mostly, and a little bit of stuff in wordpad (homework etc.), so wiping it wasn't a big deal to them, as there wasn't anything on there that they needed.

usuama, I couldn't get the memtest to run from a boot disc. I was fairly confident that I was burning an ISO image correctly so that I could boot from CD and run memtest, but it wouldn't work for me. No doubt I was messing that part up, as I've only made one other disc burned as an ISO, and that was killdisc which I still use (burned it a few months ago, well maybe 6-8 months ago). When I swapped out the ram and still got the BSOD, I saw no reason to keep trying to run the memtest when I knew that the ram was good.

Anyway, thanks for everyone's help with this. I do appreciate it. It was nice to figure out what caused a BSOD....but I hope that I don't have to deal with it again. :thumbsup:
