Computer shutting down randomly

Recently my computer has began to shut down randomly. After i turn my computer on for about 2 to 3 minutes it will just shut down. I know that it is not a problem with the CPU or the heat of the CPU, the ram, PSU, or HDD. If I leave my computer off over night I am able to have the computer on during the day for a couple hours. I do not get any message before the computer shuts down. The north bridge on my Motherboard is hot but it has been like that ever since I had it. If anyone knows a solution to this problem please help me out.
My system specs:
ASUS M2N sli deluxe nforce 570, cooler master 750 Watt PSU, AMD athlon X2 6000+, 3GB ram, nVidia 8600GTS.
 
How exactly do you figure it's not a problem with any of the components you listed? What are your system temps just out of curiosity? You can install a program like SpeedFan or Everest to view them. Also, did you recently install any hardware of software?
 
I used speedfan to see the temps. To find that it was not the processor I put a older Athlon 3200 in and the problem continued. For the ram I put in 1 GB of ram that I knew was in working condition. For the PSU I used a spare 400Watt. My CPU core was at 40 degrees Celsius, GPU 50-60 degrees, chip set usually 70 degrees Celsius.
 
Hi, not sure if this will work in your case. But have a go at it.

Right click on My Computer and select Properties.
Under Advanced, locate Startup and Recovery and click on Settings.
Uncheck, "Automatically Restart".
Click apply and close.
Reboot your computer. Does it shut off automatically now?
 
Well my computer now wont display anything on the monitor(not getting a signal). This is leading me to believe that this could possibly be a graphics card issue. Don't know how that would cause it to shut down intermittently though.
 
70*C Chipset? Wow. That does seem a bit high. Is there a HS on it or is it exposed?

No signal would make me guess a GPU, too. If you haven't already, I'd reset CMOS, then load BIOS's Optimal Defaults.
 
The chipset does have a heatsink. I have reset the bios. A couple of minutes ago I tried switching out the graphics card and I still did not have any signal. The only thing that I could think that it is now is the motherboard.
 
Well, since you already tried the other components, yeah, I'd probably swap out the MoBo next.
 
i reckpn something on the motherboard has gone,

also try reseating the memory and disconnect all hard-drives and cdroms
