My Hp Pavilion ZV5000 laptop is acting odd, when I try and boot it up it goes to the Windows Logo/Loading screen and almost directly after that goes to the Blue Screen saying that windows had to shut down in order to prevent damage to the system. It also stated that I need to perform an CHKDSK on my F drive. Only thing is I don't know how to do it. So if anyone can help me that would be AWESOME!!
