I own the PC myself. I pressed F8 to go into the options for Safe Mode but when i want to select it the keyboard freezes, it won't let me go up or down to even go into safe mode

. My keyboard only has a USB connection. I tried my old "Dodgy" keyboard where if i use it the mouse freezes!

. So i used the old keyboard, when into F8, went into safe mode, PC starts up but then the mouse has frozen so i can't click my login name
