Aziebol :
It's telling me that the thing you said to type into the command prompt isn't correct.
if you just type in sfc into the cmd prompt, it should give you the following output:
Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation. All rights reserved.
C:\Users\(myuser)>sfc
Microsoft (R) Windows (R) Resource Checker Version 6.0

Scans the integrity of all protected system files and replaces incorrect version
s with
correct Microsoft versions.
SFC [/SCANNOW] [/VERIFYONLY] [/SCANFILE=<file>] [/VERIFYFILE=<file>]
[/OFFWINDIR=<offline windows directory> /OFFBOOTDIR=<offline boot directory>
]
/SCANNOW Scans integrity of all protected system files and repairs files
with
problems when possible.
/VERIFYONLY Scans integrity of all protected system files. No repair operati
on is
performed.
/SCANFILE Scans integrity of the referenced file, repairs file if problems
are
identified. Specify full path <file>
/VERIFYFILE Verifies the integrity of the file with full path <file>. No re
pair
operation is performed.
/OFFBOOTDIR For offline repair specify the location of the offline boot dire
ctory
/OFFWINDIR For offline repair specify the location of the offline windows d
irectory
e.g.
sfc /SCANNOW
sfc /VERIFYFILE=c:\windows\system32\kernel32.dll
sfc /SCANFILE=d:\windows\system32\kernel32.dll /OFFBOOTDIR=d:\ /OFFWINDI
R=d:\windows
sfc /VERIFYONLY
youll want to take the sfc /scannow command and add the /OFFBOOTDIR=d:\ /OFFWINDI
R=d:\windows
but the d:\ is going to be what ever drive letter your hard drive is that holds the windows folder. Typically it is your C:\ drive but it could be something else.
A way to find it would be to use cd c: then type dir to list out the folders, if no windows folder is listed then move to the next letter cd d: then type dir. and so on til you find the windows folder.
IF no windows folder is found, then the drive may be dead and youll need to replace it... but since BSOD 50 is typically a bad driver, i would assume that youll come across it.
