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 ???

Hmmm... when turning the cpu ON the cpu heatsink/fan spins as normal ans what do you mean by 'first check the power management' is that on the BIOS settings ?

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?

This sounds like an overheating problem to me. I would replace the CPU fan and heat sink if it were I. They are pretty cheap. Although the fan may be rotating it may not be spinning at a high enough rate of speed to do proper cooling.

off the wall but................ check the solder joints on the caps (this happened to me a year ago) mine was cracked thus shutting down the sys. its a long shot but ya never know

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.

A recent project pic; between the CPU and the fan assembly. 83 is quite high.

Yes it is. I also use a Stanley blade (carefully) first to take off the old paste, clean up with alcohol. It is important for the 2 surfaces to be perfectly clean, no nibs, to perfectly marry up.

Mike

I would not remove the processor unless you have done this before. The most important is the melding of the fan assembly to the CPU.
My pic shows the processor still in situ.

Mike

by the way, should I spread the thermal compound after applying it ?? or should I just leave the 'pea sized' thermal paste and let the heat sink melt it???
