Question about Dell Optiplex 755 Desktop Desktop Computer
I work in a school and a child was messing around with the keyboard on a dell 755 and has managed to blank the screen- when you initially turn it on the normal screen shows and then it turns blank. I know how this can be done on a laptop but I have never seen it done on a pc - it is probably a simple key combination. Please could you help.
i believe this will help you to solve the prolem, make sure you pc is off open your case and remove a RAM from the slot and take it back again where it was on slot 1 [DIMM 1] and swicth on your pc
if mouse is giving you a problem download mouse drivers from dell company
