PC worked fine for almost 1 year. One day it was black screens “no signal detected” on my monitors. The “CPU” and “VRAM” LED lights are lit on my motherboard.

After doing a few hours of troubleshooting with different monitors, cables, ports, CMOS battery, GPU, RAM configuration it seems like the CPU is the only remaining culprit?

The thermal paste looks fine. There is no visible damage on the CPU.

I use an editing software, DaVinchi, which turns my fans up a bit but other than that I don’t do much else on the PC.

Any suggestions or ideas what I can do? Any experience if they will send replacements for their products?
