I tested it with onboard gpu still no luck

even though you re seated the ram and GPU, one of those could be faulty. just remove everything and plug in one ram (if u have 2/4 ram sticks) and turn it on to see if it shows something on the display or the indicator light starts functioning. if it works, keep on going by adding one by one until u spot the problem. if the first try with one ram didn't work, try another.
It also may not be any of those. it could be the power supply or that you need to reapply thermal paste

does your motherboard have a small on-board alarm speaker. and does it start beeping continuously or by a pattern when you remove the ram sticks?
