PC IS ON BUT NO DISPLAY

[thatayushhh]

So recently i encountered a serious problem of my pc's display suddenly going off but my is still running, the fans move, the keyboard and mouse works, the audio works and everything. It happened to me yesterday but it switched back on fine after a few restarts. Today when I was gaming, the incident happened again. I reset my RAM. I reset the CMOS battery. I checked the cables, my PSU and everything.

 

But when I connected the HDMI cable to my motherboard, it worked. But with GPU, it showed the same error. I waited a few minutes and turned my PC back on (plugged to the GPU). It turned on for a minute and then again no display. After an hour switched on my PC again. It worked fine for almost an hour and then same issue. What can be the cause of this??

 

CPU: Ryzen 5 7600

 

RAM: 1X16GB DDR5 5200MHz

 

Motherboard: B650MK

 

GPU: MSI Ventus RTX 3070Ti 3x

 

PSU: Deepcool DQ750-M-V3L 80 Plus Gold

 

I have been using this PC for the past 2 years and nothing like this happened until now.
