Laptop all screwed up, need help ASAP!!

GOD AM I PISSED, just when i fixed the DMA mode problem on my PC, my laptop then screwed up. Probably coz Friday 13th it carried on the bad luck till today as well

Anyway i need to fix this ASAP, it's very urgent and is important to me. I was using my laptop yesterday and everything was working fine, i turned it off and came back to it after a few hours and it wouldn't boot past the load screen.

It showed this error message with a BSOD background:

Stop: c0000218 {Registry File Failure} The registry cannot load the hive (file): \SystemRoot\System32\Config\SYSTEM or its log or alternate is corrupted or missing

Or something like that.

So I did some Google and tried these solutions:

http://support.microsoft.com/kb/307545/
http://swatrant.blogspot.com/2005/ [...] se_17.html

but they don't work.


I tried copying the files from cwindows/repair and overwriting it to my cwindows/system32/config folder as well as trying from CSystem Volume Information folder (where it contains System Restore backups) and i used the 2 newest PRX folders which contained the Snapshot folder with the system files in it, but both methods don't work.

Well, it did but i got the same error message except this time it's saying that the SECURITY file is corrupted or missing, i.e it shows this:

Stop: c0000218 {Registry File Failure} The registry cannot load the hive (file): \SystemRoot\System32\Config\SECURITY or its log or alternate is corrupted or missing


basically it's the same error message as the first one i posted above, except this time it's the SECURITY file that's got problem.


The thing is, i copied all 5 system files, not just one. I.E, i copied:

System
Software
Security
Sam
Default

but i just can't get it fixed.........

I have tried Chkdsk /r and Chkdsk /p

as well as FIXMBR and FIXBOOT commands, but they don't fix the problem.



Any ideas guys? I've done exactly everything advised on those sites i've posted, all the other sites i found have the same instruction/solution and i've tried them all. I really don't wanna format because i have important files on it and just way too much stuff, i don't wanna waste time reinstalling everything.....
