Hello, so about a month ago i was using a gtx 980ti gpu until it broke or i should say has some problems with it which didnt allow it to run when i installed drivers. anywho after it broke i pulled apart my PC and gave it a dust clean ( i had accidently forcefully removed my CPU as it was stuck the the liquid cooler heatsink and i wasnt able to move the needle (which you move to insert cpu and remove) I got a new GPU a R9 380 put my CPU back in as well as the new GPU turn my PC on all the fans power up and the GPU turns on as well, however i dont get any signal on my monitor linked through HDMI which the cord. I would like to know if the problem lies in my CPU? i put my old GPU in and i was receiving no signal as well on the monitor. I use a 750w power supply which is more than enough. I have also taken out the ram and put it back in as well as the battery, other than that i have no clue please halp!!
