So, when holding the 0 button on a toshiba and then proceding will it remove the os (Windows 7) cant get into my computer as it doesnt pass 'windows starting' straight after, it pops up saying along the lines of windows shut down to prevent damage.
This is happening more and more and im not sure what to do sometimes my computer starts up just fine but then on some occasions itll start up and after 5 mins or so itll show the screen. http://imgur.com/pra5HxI
