okay so i was i bit stupid and connected my hdd/sshd to my computer when it was still on ''note it was unplugged to a sata cable'', when my computer just shut down. when i tried starting it up again i got black screen before the loginn screen, but i was able to enter the bios.
i tried using repair tool to fix my startup. i even tried to recover to a previous date, but this didn't work. so i thought it may be some issue with the power connection on my moab. I unplugged everything inside ''took out the battery for 10 min'' and plugged everything back in again, but this time i got a black screen before bios and i couldn't do anything. I also got the 1 beep Dram error code. so my thought was that something is overexhausting my computer so i tried to start it up with only the basic, 1 ssd, cpu, 1 ram, and my gpu, but with the same result.
i plugged everything back in and removed the ram slot, when i start up i get the long repeating beep post. so my thought there was something wrong with my ram. i took my ram out and connected them one at the time in all different slots, but it didn't work either. so i went to another computer i build for my mom, and borrowed the ram from her computer this didn't work either, i tried her gpu also but with the same result.
since my mobo is up running and i get the post beep, it don't seems like my mobo is dead, hdd is not in fault either. so my thought is maby the psu is at fault, . i have yet to measuring the voltage with a voltmeter/multimeter.
I want to hear you opinion on this before i order new parts to my computer. is there something i have yet to try?

okay, so i checked my psu, and it seems like it was working fine, bought a new mobo and installed it, working fine now, maybe it was the circuit to the ram that was fried i don't know, but replacing the mobo seems to work for me
