Explorer.exe crashing randomly a lot

Ah, sorry I had forgotten!
Editing the registry wouldn't do anything different to what the ShellExView program does, so I guess it isn't a shell extension causing the problem this time (normally that would be the number one suspect).

yea.. :( well,i just went ahead and uploaded that crash dump file to mediafire. i dont know why it has to be such a ridiculously huge size like this. I dont know anything about coding and all that stuff so all i ever knew what to try was "analyze -v" ..and getting stupid question marks as i showed in that screenshot earlier.  :(

Hope this helps.
You could try searching on some of the entries. Nothing stood out to me as identifying the culprit here, but I'm not expert at interpreting debug logs either!

yea theres those worthless question marks. :( but i mean, it cant possibly be ntdll right ? cause that's not ever been touched since i've had this computer around 2010. it wasnt ever modified or anything like that.

i also tried searching for like ID 454, but there was no such thing in all the running exe's at the time, explorer was process ID 3916 it said, in the "process list" text file.

I'm intrigued by this entry -

Failed calling InternetOpenUrl, GLE=12029

FAULTING_IP: 
+73
077444f6 ??              ???

What exactly is that?
The last part looks like a mobile phone number.
The +73 code is for Kazakhstan.
Could that be something from a piece of malware?
:dubbio:

Doesn't seem like it cause that number is at the end of the ntdll line as a "hex" value like the other lines.

I have MalwareBytes AntiMalware and i've scanned with that several times this year with the latest defintion update(s) since this first started, and i've always come up clean (0 detections) everytime. :|

I wondered about that "internet open url" but how am i supposed to even know what caused it ? Like i said it couldnt have been the ntdll.dll cause that's not ever been touched... and that article you linked i dont understand anything about it since it's all "coding" related ...not talking about any issues or problems or crashes...so i dont have a clue what i'm supposed to look for then. :(

Does that windbg have any other more advanced commands for seeing exactly what file or whatever those question marks were referring to ?? i dont know anything about debugging stuff besides just the "analyze -v" thing which wasnt useful at all ...cause of question marks.

And as i've mentioned before, these goddamn crashes are purely no way to predict when it will happen.. maybe after a week, month... I dont have any idea how to reproduce it, cause this time it took 4 months for it just happen out of a blue while just casually doing anything like viewing images or videos in my folders, or notepad text's, or any other kinds of programs like playing games, etc etc.  :(

Unfortunately very intermittent faults which cannot be triggered at will are always extremely difficult to pin down.
I agree that ntdll.dll is extremely unlikely to be the culprit, it's recorded as having been involved in the crash, but it probably wouldn't have actually caused it.
I think the only thing you can do is to uninstall the K-Lite Codec Pack and see if the problem goes away, as it seemed to appear after you installed it.
I realise this isn't ideal, as it could be months before you can prove whether the problem has actually gone away or not!

Incidentally, you said you installed K-Lite version 13.8.5.
My understanding is that the last XP compatible version is 13.8.2, which is an update to the last compatible full version which is 13.8.0.
It is just possible that 13.8.5 does in fact contain something which isn't actually XP compatible, and is causing the problem.
I have had 13.8.2 installed for several years, and it has caused no problems, so perhaps trying that version might be an idea.

I suggest verifying if hardware is actually functioning properly. Run Prime95's stress test for several hours. Scroll down to find XP compatible version. Also, if CPU isn't fed sufficient voltage, it can't be expected to operate 100% properly.

The question marks indicate that no memory is mapped at that address or it is otherwise not readable.

ntdll!RtlpWaitOrTimerCallout+0x73

0x73 bytes into this function is the next instruction after a CALL instruction. Its address is the return address pushed onto the stack by the CALL.

IP = instruction pointer

077444f6 seems to be the callback address of the executable code for an event handler.  It was probably in a DLL that was prematurely unloaded.

Ucyborg - I doubt any hardware is causing it, this is a laptop by the way. I've never had any sort of "hard lock" or freeze's where the system would be completely frozen and forced holding power button to turn off for example. "not" talking about BSOD.

And speaking of that, i never have had any "unexpected" BSOD's before for as long as i can remember, only if it's something i know would make it happen like a PC game i cant play cause of this having a "integrated" intel graphics when i'd need nvidia/amd - which is impossible to have for this laptop. But otherwise I don't get any BSOD for reasons that im unaware of or "out of the blue"

Cpu has always been fine. I still doubt that's a cause. It's a "intel core 2 duo T 7600" not like that detail matters. :|

I always look at Event Viewer => System like once everyday or so and dont ever see any errors. only usually just "windows time didnt sync" once in awhile. but it usually always works the next day or whatever (the clock in taskbar)

Dave-H - i had the version 13.8.5 because this page is what it said...is it actually wrong ?? :(

I doubt that page is wrong, as it's the official download page from the K-Lite developers of course, but I'm sure that when 13.8.2 came out, they said that was the last XP version, because I labelled the installation file as such.
It is of course possible that they then changed their mind and produced a further XP version!
All I know is that 13.8.2 has worked for me for several years now with no problems.
It might still be worth trying it if you can find a copy, I doubt that 13.8.5 is very different.
