My brother has a computer, when he turns it on the monitor has no screen, the keyboard and mouse doesn't light up either, power button doesn't respond unless He turn off the PSU at the back with the switch. Thus he thought his motherboard went defect, so he bought a new Motherboard, CPU, the computer worked for a few days then same issue persists, he currently bought a new GPU because he put his 980TI in my computer and the same issue happened which led him to buying a new GPU... he has tried with a my PSU that is guaranteed working, he has tried reseating everything cable, reapply the CPU and changing RAMs with different working RAMs. Till the point we stumbled that we have no clue what the issue is. If anyone has a slight idea what the problem is then that would be very appreciated!
