Hello Everyone,

I'm using a Nvidia GT 1030 as my GPU for my PC. It was working all fine until i cleaned my PC for dusting purposes. Then after I'm done with cleaning my PC I switched on my PC & for no reason the monitor didn't detect my GPU though it's working fine inside. The monitor went on Power saving mode & showed nothing thereafter. (I'm using a DVI connection to plug my GPU to Monitor)

After that I tried my onboard graphics with my DVI cable & it worked fine. I've tried dozens of troubleshooting but none of them worked for me.
But i don't like using onboard because I'm a heavy gamer.
I've tried the following.

1. Resetting BIOS
2.Cleaned PCI slots & GPU
3.Disabling Onboard graphics
4.Changing monitor inputs
5.Tried for a HDMI Input

But none of them helped me. Please guys can you give me a asap solution to solve this issue.
Appreciate you all.

Thanks in advance
