did the change, problem persist, after the last freeze i decided to check all the instaltion and found this
the person that installed the pc pluged the Northbridge fan to the mobo on the front fan pin, just changed that ,also the fans were conected directly to the PSU and also to te regulator speed of the Lxa s changed that too, also i changed the speed of the cpu fan to 1900rpm iddle so my temps now are 10 C lower,
do u think one of this fact may be the respnsable of this issue ?
im gonna check my sistem for th next days and see how it works.
thanks forthe help again
I do not think the fans connections have anything to do with your freezing problems, except in the rare case where a fan connected on the motherboard would draw a lot of power, but that would usually lead to a component fail on the motherboard and that would be the end of it.
It is a good sign that your temperatures have gone down by 10C, but the CPU temp would still be high. Remove the CPU heatsink (if you have not already done so) check underneath and resit it properly.
