Problems with aswrvrt.sys (won't boot)

My Windows 7 laptop will not boot and is having problems with aswrvrt.sys. Every time I go to turn on my computer it crashes when it comes to this point. Does anyone know how I could fix this problem?

Please read the sticky at the top of this forum and follow the instructions under “if a system won’t boot”.

thanks

From the Reatogo desktop confirm that C drive is the one that contains windows then :

Run the command prompt and type in the following :

chckdsk c: /r

On completion try a reboot
If that does not work then run windows system repair two or three times
