BSOD when logging in Windows 7

It looks like your BSOD is being caused by a registry error of some manner, please begin by running th esystem file checker:

SFC.EXE /SCANNOW
Go to Start and type in "cmd.exe" (without the quotes)
At the top of the search box, right click on the cmd.exe and select "Run as adminstrator"
In the black window that opens, type "SFC.EXE /SCANNOW" (without the quotes) and press Enter.
If the program ends and says anything other than "no integrity violations found" run the command two more times.
If after the third run there are still eroors run the SFC command at boot: SFC /SCANNOW : Run in Command Prompt at Boot

Alright try running a check disk from an elevated command prompt:

Code:

chkdsk /f /r

The command will schedule a check disk for the next time you reboot, so after the command has run and the check disk is scheduled reboot the PC

srw after you run chkdsk can you verify if you could do the F8 step please .

Do you have a USB flash Drive ? Also when you tab F8 while the laptop is booting up do you get this option Repair Your Computer inside Advanced Boot Options ?
