[rundll32.exe - Application Error
The instruction at "0x7c9100e8" referenced memory at "0x01d90010". The memory could not be "read".
Click on OK to terminate the program.]


Hi, I've tried cleaning up/"fixing" my registry with Registry First Aid Premium after this error showed up, to no avail(although it assured me it fixed many many other things). I also "defragged the registry" with the same program.

I'm running XP sp3, last installed MS update was about 3 weeks ago. Memory has shown no issues, is only about 6 months old, and is high-end corsair.

I've tried Malware Bytes, Eset Nod, and checking for rootkits(unhackme)....still get the error.

I've tried inserting the XP sp3 CD(after the above) and running the command to replace rundll32.exe and restarting, still nothing.

I am using an nvidia chipset and the barrage of errors come when I open programs like games which often adjust the resolution, I also get the same error when I attempt to change my screen resolution from the control panel. Sometimes the applications still run, and I just have to close the same error box repeatedly until it goes away, with other programs it will not go away until I force quit the program that it is blocking me from accessing.

I guess I could run a full repair off the XP CD, but I was hoping to find a better solution.
Thanks in advance for the help!

#1 BC staff do not condone using registry editors as they can be more trouble than they are worth
#2 did you do a backup of your registry before you messed with it with Registry First Aid Premium
#3 I think your infected and you need to start by posting in the " Am I Infected " dept and posting a HJT log into HijackThis Logs and Analysis forum.
#4 If you can't work your way around the forums to find these then go to the home page and read :
Step 5: Are you infected with malware and can't get rid of the infections? The stop by our Malware Removal Guides section for a listing of some of the most common infections found today. If your computer is acting weird, and you think you may be infected, then maybe the Am I Infected? forum is the right place to determine if you are.

If life is not an option then why are we not given the option in the first place !

If all incidents are video-related...I think I'd just uninstall the current video drivers and the reinstall the video drivers. The current ones may be damaged, incapable of functioning properly.

Drivers often trigger messages such as you received...when they are poorly written or damaged and need replacing.

Thanks Louis, I'll try replacing the video drivers and let you know what happens.



#1 I ran Registry First Aid(which is far from Registry Patrol and other joke registry programs) AFTER the problem began, so I don't see how whether or not I backed up my registry after the fact pertains to the issue.
#2 See above.
#3 If I am infected it is deep, and I am not getting any other symptoms other than this error preventing some programs from fully launching. As I stated before I ran Malware Bytes, Eset Nod, and a rootkit check...I am familiar with my processes and nothing is acting unusual.
As for the HJT log, it was in my initial post and everything was moved to the "misplaced HJT log" forum, even though I only added the log as additional info for whomever was looking at my issue(which, by what I could tell looked completely innocent and would help rule against infection).
#4 WAT SI A 4UM

HJT log can be found here: http://www.bleepingcomputer.com/forums/ind...p;#entry1498820

*Replaced current nvidia graphics drivers, still get the same error, should I replace the chipset drivers too?

FYI: Any posting of an HJT log in the XP forum...is considered to be a misplaced posting of a malware situation. The XP forum is not designed to deal with malware issues...we try to focus on O/S issues that revolve around Windows XP.

You might take a gander at http://www.bleepingcomputer.com/forums/topic137369.html.

FWIW: If you don't consider it a malware situation, I suggest that you request that someone close your other post in our malware forum. If you intend to pursue it as a malware issue, I suggest that you stop seeking suggestions/advice here in the XP forum...that could possibly compromise the efforts of those attempting to assist you in one of the BC malware forums.

We try to avoid confusion :thumbsup:.

Louis

I would like to persue it as both a possible malware issue and a possible O/S problem..because as of now, both possibilities are on the table until one is ruled out.

I'm leaning toward O/S, but I still have no response to the HJT log to confirm it. If the HJT response confirms nothing suspicious I will request removal of the post.

My situation is analogous to my dog being sick and my taking it to a vet...and the vet telling me to take it to either a canine toxicologist if I think it is poisoned or a canine disease specialist if I think it is sick, but not both. A sick dog and a poisoned dog can have similar symptoms.

Bah...I'll do an XP repair off my sp3 disk and see what happens.

*update*
After reinstalling video drivers and chipset drivers, I have been getting the same error but with 2 other variations of it. The title will now sometimes contain RUNDLL32.EXE(caps instead of lower case) or nwiz.exe before " - Application Error".

I've also run the repair option from the windows XP sp3 installation disk without result.

Whatever the problem is, it is centered around the graphics/display software. nwiz.exe is from nvidia and works with the 8600gts I am using. When the error refers to "memory", could it be the onboard memory of the nvidia card?
