Turning on/shutting down issue

Hello,
I cannot turn on my PC at all until I unplug something, like when I try to turn it on it doesn't work, I unplug the Display port then I turn it on and after it turns on I replug it.
I also have problems with shutting down, I sit the pc down from Windows and it shows me the "shutting down" thing and then it suddenly shuts off like it's been unplugged from the wall.
I have my AC, phone, monitor, router and PC.
And I'm using some extensions and adapters because the wall plug is pretty far.
By the way I replaced my Mobo CPU, ram and GPU because the previous build had other problems.

Thanks in advance.

 

laptop won't turn on

Dell Latitude D800

few hours ago i turned the laptop off by going to start menu, shut down, on an xp machine. the computer shut down normally but now when i try to turn it back on, nothing happens for a good 30 seconds then the HDD lights and power lights come on for a few seconds then turn off.

it's weird becasue, from what i have seen, the lights usually come on right away then turn right off (in similar situations) but this thing doesn't even try to turn on for a bit. What could be wrong?

things i have tried:
-removed RAM, battery, wireless card, HDD... nothing happens
-held power button for 10 seconds with battery in and out of machine while and while nt plugged in
-Different power adapters

i am going to check the cmos battery but if anyone has any suggestions it would be appreciated.

 

laptop shut down while i first turn the power on after upgrading to win10

hello,

thanks for your help,

i follow the first step and didnt find any problem,

and then i boot my laptop in safe mode with network ,

it can successfully be shut down and turn on ,

then i leave the safe mode and turn off the windows fast startup,

now my laptop can shut down and turn on normally like it used to be,

but the problem still exist when i hibernate my laptop,

when i reboot from hibernate state , it still shut down itself after the windows icon shows up.

waiting for your suggestion, thanks!

Best regards,
