I have a Toshiba Satellite A300 19P, It was working normally a week ago, today it just won't boot.
After the initial Toshiba boot logo, I get a black screen and nothing happens, I hear the computer buzzing as usual.
I can access the boot menu normally, but the PC just won't boot to the hard drive. Is there a System diagnostics tool out there that I can use to run low-level checkups? Something that I could boot from CD?
Edit: CD won't boot either, I'm only getting a black screen. The only thing I can do is to access the BIOS menu.
Edit: Hard Drive is OK, I found another laptop, plugged the Toshiba's harddrive in and it booted without any trouble, so now I suppose it is a problem with the motherboard or maybe disk/cdrom controller.
