PC Shutting down low temps overclock

[MyGetthoRig]

Hi...I have a problem here...I have a rig that resets it self whenever I try to overclock...sometime the overclock works and sometimes it shuts down after post....my PSU is not blowing out hot air that much..usually if I overclock to 3.2Ghz...the pc just shuts down after post or somewhere in booting sequence, and restarts but shutdowns again after 2sec...then looping again and again....could anyone help me and maybe explain why am i getting such behavior, or mybe there's something I'm not aware of...

 

OH MY GOD.....LUCKY THIS POST IS STILL HERE!!! MY PC JUST SHUTDOWN WHILE TYPING THIS POST....NOT OVERCLOCKED AT ALL

PSU >>> Off brand. I think that answer your question.

 

PS:

If your PC is repeatedly shutting down due to overclocking, don't overclock.

 

PSPS:

I think you have a failed PSU and trying to overclock it with a failed PSU is a no-no, so don't force it.

how to detect a failed PSU? because I just recently bought it... because last time i upgraded my old PSU, tht PSU blows very very hot air since i upgraded my GPU to GTX650....but when I use the new one, its cooler then before, much cooler air blown out

With a system this old, the capacitors are likely failing.

 

If the PSU is as old as the CPU, its power output is likely less than half of its original rating.  As the caps age, noise increases on the PSU outputs and it is likely triggering low voltage protection or is swinging too low to power the CPU/GPU.

 

The same principal applies to capacitors on the motherboard and GPU.

 

Try your old PSU and see if the problem goes away to test the PSU.

Check with your old PSU first.

 

If the problem still happens, replace MB.  OR, look for bulging capacitors on your MB and replace them.

Thanks for the help...I tried with my old PSU and the system stabilize again....now i get it....so if i want to overclock, i need a better psu right, bcuz all the shutting down tht occured was due to insufficient power ie. Voltage i think...
