Wazzup everyone, so this pc is from my friend. He said the problem is that there's no display so I then clean up the RAM and it booted fine and ok, but after booting up to windows using it for just a few seconds it will turn off automatically, then I tried to swap my working Power Supply on this computer but still this CPU is always turning off. I really checked inside the case if there's really something wrong or blocking some stuffs, but there's none. So guys can you lend me some help ? I need your suggestions and recommendations if what causes this problem and how to solve/fix this ???

first check the power management it may be set to power down after so many minutes. If that's not it i would go under the hood and look for a loose wire from the power button to the motherboard and if there's no fan on the cpu it may be one of those things that it is over heating. just check out what i have mention above and if there is anymore problems post back.
You might also want to check for viruses/malwares outside of Windows such as a rescue cd (Kaspersky Internet Security, for example). I've seen symptoms like this cause by a shutdown script that autoruns during startup. Running from a rescue cd also adds to the diagnosis of the problem -such as faulty hardware, overheating, etc.
By the way this PC comes without an Optical drive, so I use my own optical drive to this pc and tried to insert a rescue disk on it, it booted up and read the disk but suddenly it turned off directly :( I'm very confuse why is this happening no clues about this problem, because its my first time to encounter this kind of problem. Will it because of the motherboard or what?
Go to BIOS > Power menu > Hardware Monitor - what is the CPU temperature? If it is overheating maybe it needs a fresh thermal paste (old one had dried up). If it is normal, the shutting down maybe caused by some bad capacitors, or capacitor solder joints as bubbatie1 pointed out. Can you see any bulging/leaking capacitors on the motherboard? Likewise, try a known good memory stick.
CPU Temp: 83 degrees Celsius
M/B Temp: 40 degrees Celsius
CPU fan speed: 2721 RPM
Are those results NORMAL ???
By, the way I just remove my old Heat sin/CPU fan on my old cpu and this CPU turns on and it solve the 'sudden turn-off' problem, but the cpu temp seems to be so hot? I just wanna ask if HOW do I re-apply the thermal paste on the processor or in the heat sink/cpu fan ???
