    My computer hanged up, I ran safe mode and found out it froze at agp440.sys. I used the recovery console to disable that, but now it hangs at Mup.sys.

    I tried doing a chkdisk, but I am confused as what exactly to type?


    So what I type in recovery console is exactly:


    But it says the command is not recognized? Can somebody please tell me how to fix what I wrote? When I type chkdsk it just tells me the status but I need it to run the chkdsk and recover errors. Thank you so much in advance!!!!

    BTW, sometimes safe mode can take a very long time to load (up to 10 minutes) and only seems to hang at a certain point.
