Hi Guys, I am working on a Toshiba Satellite l655 (that was dropped) and I am having an issue, it doesn't boot up. I turn it on and it just stays at black screen with a flashing underscore. I tried pressing F2, F12, F8 and all it does is makes a loud annoying beep everytime I press any key. At first It says there was a problem with the hard drive. It said " A DISK ERROR HAS OCCURED, PRESS CTRL+ALT+DEL TO RESTART." I opened up the laptop, unplugged everything, checked to connections and tried it again, same thing happened. I even connected that HDD to my desktop and it couldn't find it. I bought a new HDD and now the screen just stays black with the flashing underscore. I still can't get the boot menu, can't even get in to the BIOS. Can anyone help me with this issue??
