I have a dell OptiPlex pc she's an old beast it had xp running on it but as xp is now not supported I tried to upgrade it to windows 8.
All was going well putting the windows 8 disc in waiting for it to go through its loading process, And then it all went down hill from there it was due to do it's restart to load up the win 8 OS and now it appears to be dead.

All I get is the dell load up screen with the options of pressing f2 or f12 and that's as far as it goes I'm stuck with a black screen nothing loads from the HDD or from the dvd in built player or even from the portable dvd writer I have to get it to work even usb doesn't work I'm at a loss what to do or should I just bin the pc all together
