So my Toshiba laptop started going black last night. Okay, so I would close the laptop then re-open it and it would turn on fine. But if I let it go too long its like it goes t hibernation mode (it doesn't). So I decided to do a reinstall of the system. I restarted the laptop, put my disc in, the laptop started to put I pressed F8 then the screen went black again. Now whenever I started the laptop, past the boot stage its just goes black.
