I was using my laptop earlier when it crashed. I booted it back up and the hard drive made weird beep sounding fan noise and it sounds like the hard drive is singing. It does this during the time when it shows the Toshiba logo and stops when the logo goes away. After the logo goes away the screen just goes black. It makes normal sounding noises after the logo goes away as well. I have a Toshiba Satellite C675 and a WD black 500 gb hard drive. When I open my boot menu it says in the hard drive slot HDD/SSD: PATA: but nothing else. It also never used to say PATA in the boot menu. If someone could tell me what is wrong with my laptop that would be great. Thanks in advance.
