Pc boots but no display

[Yugansh]

What actually happened until yesterday my pc was completely fine and from today whenever i try to boot my pc my graphics card fan goes like a jet plane and my pc does post but i get no video output i have tested the monitor with my laptop it works so what is what's wrong is the pcie slot bad or is my graphics card itself mal-functioning . I have a Core i5 4460 with 16gb of ram asus b85mg and a gtx 1050ti 4gb v ram i have re installed my gpu and the output from igpu is fine and also i have reinstalled ram cleared cmos and more

Because you have tried using the output from your iGPU, you can assume that your graphics card is not the cause. I would check all the power connections on the motherboard.
