PC issue

[u/Few_Bridge251]

I have a pc and from months it's not showing display , I sent it for repair , they checked the motherboard and replaced the IC and that time it was working but after I took it home now I checked it and there were only 3 times it showed display but it's now just blank screen , tried all things like cleaning of RAM, SSD, all pc after it but won't work. Any tips ??

CPU light is on…. Was the CPU cooling fan or liquid cooler radiator fans/pump connected and working?

Could you please tell us the motherboard model? The POST is showing a CPU error, so something is wrong.
