I had upgraded my pc to windows 11 but after 2 days my pc is not displaying anything on monitor. It only says INPUT SIGNAL NOT FOUND. CHECK VIDEO CABLE OR VIDEO SOURCE.
I have tried many fixes but got no success.
Tried method :-
1. Checked hdmi cable.It is functioning well on other device.
2.Cleaned the ram stick.
3 Tried removing CMOS battery.
4. Tried removing graphics card.
All these methods could not fix the problem.
