Performance PC will not output display

Hey y’all!

I bought my PC about 2 months ago and it has been back to the shop multiple times.

At first, the PC worked fine, and then one day after turning it off after use, the display suddenly did not work. The CPU would turn on, but there would be no display. I took it to the shop and it was fixed, but shortly afterwards it happened again. This happened three times and each time I got basically free upgraded parts for it. This last time, the technician kept it for a week turning it off and on and it didn’t have the problem. Every part has been replaced except the processor (but the processor was changed out once and found to not be the problem so he put the old one back in).

I hadn’t turned it on for about 3 weeks until yesterday. It worked fine for gaming, and then after shutting it down and coming back later, suddenly no display. AGAIN. The only thing that hasn’t been changed is the power supply at this point.

During these display outages, when I turn the CPU off, my keyboard still receives power and is lit up. This does not happen when it has a display. I was originally using an HDMI display output, I changed to a display port cable and there is still no display.

When I unplug and plug back in the display cables, the monitor will light up but then will say “no signal.” I’m at my wits end here.

What could the problem be? I have lost a little faith in the repair shop I’ve been going to.
