Hey guys, I have a problem on my Samsung Series 5 Laptop, the laptop was really fast but for unknown reasons it slowed down, I'll tell what happens : Boot time is extremely slow, frequent hangs, cant open most of my programs and my files, disk check stuck at 2%; it happens after i turn on my laptop. How do I fix this? Cant even open the cleaners of my laptop (antivirus,disk scanner,etc.) only the disk check at after i turn on my laptop works and fails 
Edit: Errors always show up when laptop is booted.
