Blue screen issue with Windows XP please help.

[btcomm1]

I have 2 HP computers here, they were working fine now not so much. They have very similiar issues. If I boot either into safe mode they are fine. They both have Windows XP SP2.

One of them if I boot into normal windows mode the desktop will come up then about 5 seconds later I get a blue screen that says.

*** STOP: 0x0000007F (0x00000000,0x00000000,0x00000000,0x00000000)

Beginning dump of Phyical memory

Phyical memory dump complete.

I have already disabled all startup items in msconfig and disabled all services including microsoft services and the same thing happens.

The other HP will boot normally will let you sit on the desktop. If you browse web sites it's fine but if you try to download a file when you click save it gives you the same blue screen.

but if you try to download any file you get the same blue screen.

*** STOP: 0x0000007F (0x00000000,0x00000000,0x00000000,0x00000000)

Beginning dump of Phyical memory

Phyical memory dump complete.

If I use firefox it will let me download.

I have already run memtest86 and the ram tests fine. I have done a chkdsk c: /f and still I get the same thing.

If I let the computer sit at the windows login screen it doesn't have a problem.

I tried creating another user account and logging into that but the same thing happens.

Has anyone seen an issue like this before? What could it be?

Well, BSOD is always driver issues or bad hardware. Since something similar is happening on both machines I'm going to go with drivers. Look in Device Manager (control panel -> system -> harwdare -> device manager) to see if any of the devices have an exclamation point next to them or are otherwise indicating an error. You can try disabling devices and then reenabling them one by one, or simply try to make sure you have all the latest drivers installed. If none of that helps then I would do a reformat/resinstall of the OS.

 

[btcomm1]

You might be on to something.

Devices still show up in safe mode right? Well on this computer device manager shows nothing while in safe mode.

 

[bruceb]

I tend to agree ... sounds like a driver issue
Did you let Windows Auto Update do any driver updates ? ?

If you did do a Roll Back to the Prior Drivers and see what happens.
Best if you need to update any drivers is to get them from the
maker of whatever you are trying to update.

Well, I found out that the errors on one of them has been happening much longer and I don't think system restore goes back that far. On this one that has the problem right on boot the problem just started yesterday, however some how system restore got disabled on it so it isn't going to be much help. Maybe I can do a windows repair with the windows CD? If I Do that does it leave the user profile and the user alone or does it make me make a new one?

Also does it require a cd key to do a repair?

 

[Markbnj]

System Restore is often flaky anyway, and I hesitate to use it to go back more than a day or so, say to get rid of a bad patch or something. As for Safe Mode, that disables a large part of the system, everything basically except local i/o and video, so you might not see much. I haven't looked at it specifically when in Safe Mode, but I would expect to still see a few of the system devices.

Unless you're absolutely wedded to irreplaceable aspects of the current installs, I would just blow 'em both out and reformat.

 

[btcomm1]

Would a repair require a cd key?

I checked on another computer and device manager should show devices even in safe mode.

 

[Markbnj]

I don't believe repair requires a key, but a complete reinstall does.

 

[dclive]

Prior to reformatting, which may just put the problem back in place once you reinstall your device drivers, I suggest giving me the (zipped) minidumps, found in c:\windows\minidumps, and also running MPSReports (see my .sig) and sending me the computername_mpsreports.cab file. I can look at the dump and I'll see if I can tell you why your computers are crashing.

Obviously, I'll need both files from both machines, clearly identified as to which is which and when the problems happen with each.

 

[btcomm1]

Should I send you all the dumps or just the most recent?

All.

All. And in all correspondence, please include the URL of this thread. (Yep, ALL e-mails. Please.)

Anyway, I got the one dump you sent (from just one of the two computers having the problem - aren't there two having a problem?

For the one computer you sent, and the one dumpfile you sent, you need to completely remove avg from your machine. Remove it - entirely and completely.

Module[ 71] [C:\WINDOWS\SYSTEM32\DRIVERS\AVG7CORE.SYS]
Company Name: GRISOFT, s.r.o.
File Description: AVG Scanning Engine
Product Version: (7.1:0.407)
File Version: (7.1:0.407)
File Size (bytes): 778656
File Date: Tue Sep 26 08:29:49 2006

is what caused your dump, on that one machine, that one time.

 

[btcomm1]

You are amazing dclive. What do you use to find all this info out from the dump? I have a feeling it is what is causing the problem on the other also but as far as I was aware AVG works properly with windows XP so do you think it got corrupt on both computers? I will send you the files from the other and will send you the rest of the dumps. I'm repairing windows XP right now because I wasn't paintient enough but I will send the files as soon as I can.

 

[dclive]

See my .sig for my brand new (baby! be gentle...) web page on how to open and look at a memory dump. It's very simple at this time; I'll add more if people like it and it's useful to someone.

You ought to read the web page - the example I showed is based on your memory dump. You can easily reproduce how to discover the problem.

 

[bruceb]

Just an opinon, but AVG in my view has been very steady.
You might do as he says, fully remove it, it's folders & reg
keys, reboot, then download the latest version from their website,
reinstall it and update it's definitions file ... then see what happens.
If the computer still has problems, then you will need someother
antivirus

It might be nice to sticky the links to your site about troubleshooting
BSOD ... very interesting read ... and good to know who / where
to go when it happens.

Bruceb:
AVG7CORE.SYS caused his problem. In some systems, AVG isn't as stable as you've seen. Debuggers are very, very good at pinpointing the problem. If it said avg7core (and it did), that's the most reliable and best information we've got that that's what caused the issue.

btcomm1: I suggest keeping avg off until you're convinced that was the cause of the instability, then investigate another AV product. You're running the version from Sept 2006 by the looks of it, so I question if there is a newer update.

 

[btcomm1]

Let me give you an update, this HP did not come with a windows CD, so I used recovery using F10 it took a while, and now it's stuck at the thank you screen! Why can't it just work right? The thing is, even though it's been at that screen now for 30 minutes the hard drive still appears to be doing something.

FWIW I have had AVG wreak havoc on a few XP systems as of late. Some pop up a stop error, others have modules disabled, etc.

Switching to an alternative AV has remedied the problem.

 

[dclive]

I have no idea how HP's F10 recovery partitions work, but you could always call them and ask for CDs.

 

[btcomm1]

You were right DClive, I uninstalled AVG in safe mode and rebooted and no more crash. I have a good feeling that AVG is the cause of the problem on the other computer as well. How could AVG get corrupted on both computers like that and can I trust it in the future? Oh yeah and I found out that device manager didn't have anything in it because in an effort to troubleshoot this computer I disabled all startup services including all microsoft ones. So it seems to be working fine. I was thinking about downloading latest AVG and installing and updating it to see if any problems come up.

So in some systems it's just not stable? You mean because of a hardware configuration they have or something? These computers were working with AVG for a while with no problem.

Ok, here is an update. I just installed AVG, updated it to the newest it was running but I rebooted the computer and now it's back to it's old blue screen again. It's definetly AVG is there something wrong with windows that would cause it not to work?

I mean I have AVG installed on another computer, same version, totally updated and when I reboot I don't get a blue screen.

 

[dclive]

I can't comment on your AVG questions except to say that obviously they've got some work to do.

Did the debugger info on the web page make sense to you? That's your memory dump there.....

 

[btcomm1]

What free anti virus would you suggest instead of AVG?

 

[dclive]

I'd suggest Symantec Corporate Edition. gotapex or techbargains or bensbargains show it on special every so often - 3 licenses for $30 or thereabouts.

 

[btcomm1]

dclive, I just read your website nice. I opened the crash dump with debugger and bam right there showed the AVG file. This will definetly be helpful in teh future. Thank you much.

What were you looking for in the MPSReports though? Is there anything in there that would explain why AVG has problems on these computers yet on others it functions without a problem?

Oh yeah and I tested the dump files on the other computer and wouldn't you guess it AVG is the culprit again.

 

[dclive]

Computers are different, regardless of how much they may look similar, and so the same software can impact them in different ways. Just because a product worked on 1000 computers doesn't mean it will work on the next 1000.

If you really wanted to help AVG, send them those dump files and ask their developers to fix it. Most people don't bother, and they just switch to another product.
