@lakisha3336 a complete blue screen would mean that you are not getting a video signal. You need to try every video input to see if it is the same for all different inputs. That would be a main board issue. Since you did not give us a model etc., we can’t provide a whole lot of information regarding the repair.

Check the voltages on the FRC module’s 1117 regulator. (the regulator is the three legged device just up and to the left of the big IC) The reading should be from top to bottom with respect to chassis ground. .6v 1.8v 3.3v If t=he bottom number is not right, either the Main board is bad or check all the power supply voltages.
