Hi,

I saw another post with the same problem as I have, which is my computer will not start in normal or safe mode. I just get the BSOD and the error code STOP: 0x0000007B (0xB84C7524, 0xC0000034, 0x00000000, 0x00000000). I assume this is a virus of sorts, but I have been getting the BSOD periodically for a while now.

I have taken a few initiative steps to help speed up the diagnosis process and make your job a little easier...I hope.

What I did was follow the instructions of the other BSOD post and created a boot CD with PE Builder and scanned my hard drive with OTLPE from a flash drive.

I have the two files (OTL.txt and Extras.txt) that were produced from the scan and will post them if they are what you are wanting. If not, please let me know what you would like me to do.

Thanks in advance for any help you are able to give.

Point #1: It is never wise...to take specific information given to and applied by one person...with malware...and try to use it as you attempt to correct your own malware situation. The variables are too many to enumerate and it is my opinion that it is dubious that your situation truly parallels that of the person for whom the advice was intended.

Point #2: All malware logs (DDS, OTL, HJT, CF) are not to be posted in any forum other than the BC Virus, Trojan, Spyware, and Malware Removal Logs - http://www.bleepingcomputer.com/forums/forum22.html .

If you wish to post a malware log, please read and follow Steps 6-9 of the Preparation Guide, Before Using Malware Removal Tools and Requesting Help - http://www.bleepingcomputer.com/forums/topic34773.html .

By doing the above, you will get the benefit of those who are trained and experienced in dealing with malware situations...while this is not possible here in the XP forum.

Hello, if you have the OTLPE logs, please post them. Once you do so, I'll move this topic to a more appropriate forum and will have a look at them.

regards, Elise

My apologies for posting in the wrong forum, I didn't realize I had done that.

Here are the log files from my scan.

Thanks for the help! :)

Hi again, please rerun OTLPE, and copy/paste the following text into the "custom scan/fixes" field. Click Run Fix. Afterwards, try to reboot normally.

Hi,

I reran the OTLPE with the fix and the system started, but had some problems. So I restarted the system and I have the same BSOD problem with the same error code.

I tried the fix again and the log shows "dfasdvcx.sys not found".

I'm assuming there are more files there that need to be deleted.

Has the stop code changed?

When you try to reboot in safe mode, what is the last driver you see on screen before the BSOD?

regards, Elise

When I booted up my computer to find out if the stop code was the same, it actually booted to my desktop, but did not have the task bar, or icons, just the desktop. Then I went to check the last driver on the screen when booting into safe mode and it actually booted into safe mode.

I don't know if it's fully functional, but it appears to be.

I have not done anything extra since my last post, so I have no idea why it would suddenly do these things.

Update:

I have a slave drive that I unhooked and my computer now seems to boot as good as it did before. I don't think it was the cause of the first BSOD, but for some reason it is now keeping the system from booting.

As soon as I hook the slave drive back up, I get the BSOD and a stop code as soon as the windows loading screen comes up.

The code is not quite the same as the first one and reads stop 0x0000007B (0xB84CB524, 0xC0000034, 0x00000000, 0x00000000)


Any ideas?

If the slave drive is IDE, make sure the jumpers are set to Slave (and not to Master).

In the BIOS, check also which drive is listed first as bootable device. Does this slave drive contain an (old) windows installation?

I double checked the jumpers and they are set correctly to slave.

I also double checked the BIOS and correct drive is listed first.

The slave drive used to have a version of windows on it, but I deleted it quite a long time ago.

The whole thing was working perfectly fine a couple of days ago...I have no idea why the slave would suddenly act up.

Thanks!!
