I'm pretty sure my secondary computer still works as it boots up and I can hear it running. But no matter which monitor I plug up, no image shows on the screen. I don't know if it's related to the graphics card or some other issue. Last time I tried to boot in safe mode, the keyboard was not recognized. Any suggestions? Or, is this a lost cause?
This happened to my last laptop before I changed it, and when I brought it to be checked at service center, they told me it had something to do with mother board or something similar. They didn't mention graphic card. But mother board is a serious element so it's rather expensive, I decided to go with a new laptop instead, haha.
I think it is something related to your motherboard graphics card, or you can also have a change of your cable wire connecting the monitor from the CPU.
