I turned on my dell this morning, boots up then all of a sudden comes to this blue screen saying:

 

 


STOP:c0000221{Bad Image Checksum}

The image urlmon.dll is possibly corrupt. The head checksum does not match the computed checksum.


 

 

I have no clue what do to. Should I try the windows boot disk? Someone please help!!!!

Try booting in safe mode. Press F8 a bunch, or hold it down, when the comp first turns on.

Then you can at least try to backup anything you really don't want to lose.

My Windows screwed up on me sort of like this a week ago. It just wouldn't boot up anymore, but it eventually couldn't even get into safe mode when I kept trying to do different things to get it going. Using the last settings that worked didn't help, either. Sometimes, Windows just screws up, especially if you have had it on there for a good while.

I eventually found my XP disc and just booted from it and reinstalled Windows.

If you just repair it, instead of formatting, you might be able to fix it. It happened to work for me, for whatever reason.

When I chose repair, it went into DOS mode for some reason, and I couldn't get it to do anything, so I restarted and tried to format and reinstall. However, that time, it came up with a warning saying that it detected an installation of Windows that was already there, and asked me if I wanted to repair it. It worked there, for whatever reason.

I only had two issues, and they were both easily resolved.

The first was that it made me get a new confirmation ID, as the disc I used did not come with my computer and the key does not work for it. It wouldn't let me log in, except in safe mode with no networking. You just call the number it gives you though, and someone will just tell you a new one.

The second issue is that it left some aspects of SP2, like the firewall, but they would not work, and it took a long time to completely boot up once it got to the "Welcome" screen. I ran MS Update right after I reinstalled, but it didn't get SP2 the first time for some reason, and I didn't catch it for a few days.

All is fine and dandy now. Good luck!

Us computer guys usually call this "the blue screen of death". There's usually no way around it.

 

I would re-install windows.

 

If you wish to use that as a last resorts (because of important files being lost) I would contact somebody near you to look at it.

 

In my experience once you get this, you're done. But that's not saying there's no other way..That's just what I've seen.

 

Good luck.

Unless you need it to open saved Word files, which I'm not sure if it can do or not, you can download Open Office for free. It's pretty good:

 

http://download.openoffice.org/index.html

 

It's kind of funny, because it's basically MS Office with everything organized differently. If you use the help function, it tells you what the MS Office program functions are called in Open Office and where they're located in the menus hehe.

:confused:



reinstall the modem drivers?

did you make sure you set up the connection properly?

if you cant connect, why are you here? LOL

do the simple things first...uninstall and reinstall the drivers, and check to make sure the connection is set up correctly.

Bleh. I didnt see that. What a horrible option to have to do. I hope you didnt reinstall it over itself and instead formatted and started fresh. Otherwise you are going to have so many possible problems with file versions for DLLs and Device Drivers etc etc.

All you have to do is try to replace the file or check your RAM.


A checksum is basically a number generated by treating all the data in a file of whatever type to generate a number based on some irrelevant algorithmn (usually MD5). It will generate a consistant unique checksum for any data. If the data changes, even by one bit, then the checksum will change...usually drastically. Windows is telling you that when it compared the saved checksum of that DLL (dynamic loadable library - used by application that share common routines so that save memory resident space when executed. basically if two programs both use the exact same function, instead of both programs using X bytes in memory to store that function, the function is stored in a shared memory space so that both programs may use it) the new checksum and the old do not match, so the file has changed is is probably due to corruption.


Reasons this might happen? Something called data rot. Common in Windows and the quick and simple explination is that File Allocation Tables are prone to errors. When a file is made up of non-contiguious data, it usually points to the next block that contains the continuing data. Sometimes these pointers get screwed up for whatever reason and you lose pieces of the file. Another common reason is because of bad RAM. Everything that is executed by the CPU has to pass trough RAM. (exceptions are ofcoure opcodes and register data). When you edit a file, you are editing a copy of it in RAM. When you close the file, the copy in RAM is written to disk. Whatever was in RAM replaces your file. If your RAM is bad, you might get bad data saved back to disk. The same applies when stuff is stored in RAM for execution. Your CPU has only a VERY finite space to hold data that its executing. Gerenally what cant fit inside a register (32 or 64 bits on Intel processors) is first attempted to be stored in L1 cache, very fast RAM. You generally have no more than 1K of L1 cache (but 1k is a TON of space for a executable file), what it cant fit in L1, it has to store in the RAM thats external to the CPU. Thats the stuff you stick on the MB and can upgrade. When the CPU requests data from L1, and its not there, it gets if from the external RAM. If the DLL that the CPU needs is not in ext RAM, it copied it from disk and feeds it to L1 cache and to the CPU. What may have been prefectly fine on the disk, when copied to a bad Memory Module, can end up as corruped data when it gets to L1 cache. THis is why it says that it may be your RAM. If replacing the file doesnt work, then there is a chance its the Memory Module.


cheers

 

 

You rock!

 

Unfortunately, I've never met a user with a broken box, that had 1/1000 the patience to read through that. Everybody wants instant gratification, with no investment of understanding.

Appreciated Squealie. I do programming and admin for a living. As long as I am not on the clock, I enjoy solving computer problems. ;)
