HP Recommended
Product: p6-2420t
Operating System: Microsoft Windows 8.1 (32-bit)

I went to restart my computer and got the blue screen message "System Thread Exception not handled (AmUStor.sys)". The computer restarts but always comes back this same screen.  I have tried less invasive System Recovery options like:

 

>system restore (several times): says I cannot complete because it cannot open a file, likely due to and  antivirus program.

 

>using the command prompt: but any command I try to use "is not recognized as an internal or I external command, operable progam or batch file."

 

>I read a solution that involves booting in safe mode, but changing boot options is not listed under advanced options.

 

What to do?
