I was told to come here from the malware guys
I'm using an old Toshiba Satellite L300D-01N. It's been working fine for a while. Suddenly last night, it just randomly powered off on me (It didn't just go black, like it actually went to "Windows is shutting down etc..)
I had assumed it was out of power (even though it was plugged in) so I let it charge for the night using the same charger it always used. Now when I try to turn it on it shows the Toshiba loading screen, then the Windows Loading screen for a couple seconds, then a sort of blue box flashes and it goes back to the Toshiba loading screen.
I tried starting windows normally, and starting from last known working state or whatever its called, but the same thing still happens.
I reallly need this working again!
EDIT: Actually its more like 2 blue boxes flash at each bottom corner of the screen after a very brief few seconds of the Windows load up screen.
