have a hp 450f desktop - got blue screen yesterday while working - now cant get computer to boot from disk or anything else - none of the function keys make a difference, the screen remains black - nothing comes up.
Can anyone help me get this thng to boot so I can do a total recovery to manufacturer's settings? I backed up a few days ago, but had to do it by physically moving stuff I wanted to keep - it wouldnt make a shadow copy nor backup any other way.
no choice, how do I get this to even boot up so I can select what to do? thanks, need help asap.
