Windows 7: The page failed to load.. Dump File Plz Analyze

The page failed to load.. Dump File Plz Analyze

I get the error "The page failed to load" in control panel, but for a strange reason, it only occurs on every 5th attempt at opening a setting.

After this error, explorer.exe will either freeze/crash (and I need to kill it) or it'll just sit there still trying to load the page but allows me to close the window without it crashing.

How I reproduce the error:

1. I open control panel
2. It doesn't really matter which setting I choose to open, but for testing purposes I open "Ease of Access Center"
3. The first 4 times I open Ease of Access Center it loads just fine
4. The 5th time it shows a blank page with that error message centered!?

This seems to happen only on the 5th time and it seems to apply to the majority of the settings in control panel. I am absolutely clueless on the fix. It doesn't do this in safe mode. I suspect it could be a driver or just something in the registry but I'd love to be able to narrow this down and find the culprit without reinstalling clean.

Kudos for the desire to get straight to the debugging phase of troubleshooting, but there's a problem- what you're experiencing is not technically a "crash" in the sense that a process terminated in an abnormal way.

Not every error message constitutes a crash.

As a wild guess, is your UxTheme.DLL "patched" perhaps?

It shouldn't be, as I've never touched that file before. The only theme changes I made was disabling Aero, and changing the colors a bit. I can also replicate this error by creating a second user account (which I believe uses the default Aero theme). I've tried closing every program running in the background and the error still persists, and always on the 5th attempt. I am stuck at figuring this out!

I can start uninstalling some files that effect the context menu as a precaution though. Eraser, WinRAR, 7-Zip, and AntiVir, but these are all widely used software and can't imagine that being the cause. =/
As a suggestion, remove "-noDumpOnFirst" from the command line you used to attach the debugger, and then repro the problem again. Actually, you should reboot first before doing anything else.

Without the "-noDumpOnFirst" switch, you might get some DMP files appearing at the time of the problem.

To cut a long story short, a "first-chance exception" is sort of like a half crash (I hate myself for using that analogy). Normally, first-chance exceptions are of very little interest when troubleshooting "real" (second-chance) crashes, hence the use of the "-noDumpOnFirst" switch, but in this instance it may actually be interesting to see those first-chance exception events.

Tried to use a .Net Cleanup Tool just for the sake of trying it, but it didn't do any good. Also ran "sfc /scannow" and it shows no signs of problems with system files.

Rebooted. Error still exists. Created new dump without "-noDumpOnFirst"

I really appreciate your help, I have my fingers crossed hoping I don't have to reinstall 7.

Hmm, still no dumpy goodness, just text files. We'd probably have to play with the debugger itself, but doing it over a web forum is like keyhole surgery without being able to see what you're doing, and I'm not confident that I'd be able to justify the time we'd spend on the basis of a guaranteed positive outcome.

Anyway, I can sort of see what's happening on a code level from the info in those log files: a COM object that's being called is somehow dying, although I can't tell which COM object without a dump.

From the two 1st-chance exception stacks in the log:

# ChildEBP RetAddr Args to Child
WARNING: Stack unwind information not available. Following frames may be wrong.
00 03c0ee80 77c98f48 800401fd 00000001 00000000 KERNELBASE!RaiseException+0x54

...

And:

# ChildEBP RetAddr Args to Child
WARNING: Stack unwind information not available. Following frames may be wrong.
00 0009e870 77c98f48 80010012 00000001 00000000 KERNELBASE!RaiseException+0x54

04 0009ece8 7773c8b5 00000010 00000005 0009ed20 ole32!WdtpInterfacePointer_UserUnmarshal+0x60d


Those two exceptions map to the following:

800401fd = CO_E_OBJNOTCONNECTED

80010012 = RPC_E_SERVER_DIED_DNE

=======================================

Is there a COM or RPC error/warning event in the event logs at the time of the problem? (Run EVENTVWR to get to the event log.)

I don't see any COM, RPC, or any strange errors/warnings in the event viewer.

Steps Taken:
1. Open Event Viewer
2. Replicated Error
3. Looked within the Last hour under the Summary of Administrative Events
4. No errors within time frame of test. I don't see any COM, RPC, or any strange errors that may be related.

Unfortunately, that makes things more difficult as the limited amount of info doesn't reveal which COM object is going ga-ga.

As a suggestion, test what happens when you use MSCONFIG to specify a "diagnostic" startup and then reboot - can you still repro the symptom in that mode?

Yes, I can still repro the error in diagnostic mode. However, that is very odd because I can NOT repro the error in safe mode.

Another unfortunate outcome.

Diagnostic startup is not quite as sparse as running in safe mode. Hence, the problem in this instance is obviously caused by one of the differences. Suggestions:

1) Test what happens when you disable Aero (pick the Windows 7 basic theme). Is the error reproducible?

2) As a separate test, issue this command on an elevated (run as admin) CMD prompt and reboot:

BCDEDIT /SET VGA ON

After the reboot, you'll be in "basevideo" mode. It would be interesting to know whether the problem is still reproducible because it would mean it's got nothing to do with the video rendering/driver.
