If you have unplugged your X51 R2 from the power supply and it still turns itself on and then back off within two seconds, you have a bigger problem than just a faulty PC. "Who You Gonna Call..."
Just joking.
I suppose you'll need to debug this from scratch. Did it just stop working out of the blue or was it unused for months before you tried powering it on again?

im sure you re-seated all power cords from PC to wall. (no power strip bull)
all bad PCs can do that, if you google here is 30 years of PCs that all did that, only why remains.
1: a device connected to the PC inside or outside is shorted (called and overload, preventing nasty fire and smoke)
2: the PSU is bad.
3: overheated CPU (fan falls off or dead, or heatsinks fall off, easy. seen vast times myself (shipping damaged)
all PCs do that by design for that reason FIRE.
the ATX spec, for you PSU tells you it can do that in 1 second or less, even 16/1000th of second on my fancy new DPS PSU,
or even instantly.
IT;s a feature.
the cure is stripdown testing ,
start by removing all USB devices, if one shorts out the PC can in fact turn off under 1second flat or hard boot.
then the cover. off and more work. you can't fix bad hardware, staring at it , takes hands on, covers left off.
