ok guys update i finally found the cause of it turn out for some reason the psu cable that i got from my own one (coolermaster v750) doesnt suit the psu on my friend one also from coolermaster (CoolerMaster MWE 750W F/M 80+Gold)  once i used his one it worked why does this happen? i thought all pci-e psu cable are the same?   

the pin outs on different PSUs even from the same brand may be slightly different. Sometimes it is different even for the same series but of different generations.

Go step by step to diagnose your problem: Disconnect everything unnecessary for boot (GPU, hard drives, etc) and see what happens when you try and boot. If nothing happens still, your issue is most likely with your power supply or motherboard (or power from the wall, always make sure you haven't blown a fuse somewhere in your house :P). If it boots correctly, reconnect devices one by one to find out where the problem lies.

Desktop:     Core i7-9700K @ 5.1GHz all-core = ASRock Z390 Taichi Ultimate = 16GB HyperX Predator DDR4 @ 3600MHz = Asus ROG Strix 3060ti (non LHR) = Samsung 970 EVO 500GB M.2 SSD = ASUS PG279Q

 

Notebook:  Clevo P651RG-G = Core i7 6820HK = 16GB HyperX Impact DDR4 2133MHz = GTX 980M = 1080p IPS G-Sync = Samsung SM951 256GB M.2 SSD + Samsung 850 Pro 256GB SSD
