Blue screen! Do you know this Index error code?

From Two days i trying to searching in every web and in every languageto try to understand the solution at for my problem!!

And i'm here to please you to save me from this situation where i'm so confused!!

My real problem is that i can't access to system in not any modality because there is an error message (Bluescreen that surely block the loading of someone main functions ...

This is the message reported from blue screen with relative index error (that i'm not succed to understand:

STOP: c00021a {Fatal System Error}
The initial session process or system process terminated unexpectedly with a status of 0x00000000 (0xc0000428 0x00100498).
Report errore Diagnosi recovery tool

How can I to make and to read the dumpings file? I can't acces to login screen?

Of course the sampler solution would be to rewrite windows 7 in these cases (when it goes well!)
Ma ci sono tanti programmi grossi (che uso per lavoro) collegati al sistema che non posso perdere!
I'm trying to study and to learn more possible slight knowledge about function of system's files in order to succeed to resolve these problems, but now I find up sea!
Can someone give a straight one to me in order to orient to me or must be resigned to rewrite or formatingat this time?!

Sorry sorry sorry for my english!
I hope that some word can be understandig!!!
Thanks in advance!

If you have already really tried a "repair install" then all you can do is put in your W7 disc and do a full repair from there. What you need is a boot (if needed by cd-rom) that allows you to do some system and hardware checking and not crash immediately...

1. did you really try a repair install and that did not do anything? Did it not run or did it run with no omprovement?
2. Do you have a W7 disc you can use to boot with?

Just in case: is your Bios up to date and are you NOT overclocking...?
