Wrong cpu temperature in pc health

i got the gigabyte GA-MA78GM-S2H motherboard with the athlon 5000+
cpu and the problem is that my system always shuts down as soon as the cpu is running at more then 80 percent workload. Every time i boot my system the pc health shows a cpu temperature of 50°C wich ofcourse has to be wrong because the system is idle at that point. I use the stock settings for my cpu : 2.6 ghz and 1.35 V I noticed when i decrease the speed to 2.00 Ghz and the voltage to 1.15 V only then i can use my system normally.
Is this a fault of the motherboard or is there a problem with the cpu that prevents using the cpu at stock settings? And if the motherboard is the problem is there some kind of bios hack?

list the rest of your specs. we need more info to try and help.

but from what you listed here, the problem might be:

1) cpu is overheating, what kind of heatsink are you using? try reseating it.

2) your power supply is bunk, what brand and wattage is it?

I use one sata 300 harddrive 7200 rpm from western digital and for the graphics
i use the build in 780 G to make my system more enery efficient.
The cpu uses the stock heatsink from amd and my power supply is 350 watt from chieftec (model rev: s1f ) I returned my system before the the local pc shop and
the heatsink has been tested. I touched it before and it is not hot at all !

1) is likely the culprit, your CPU can easily be 50°C at idle if either: your fan/sink retaining mechanism is not fully engaged on all four pins, or your TIM application was ineffective; pull your MOBO; flip it over; check all four pins for proper engagement. Usually, an inner pin expands an outer retaining 'spade profiled' mechanism, and then rotates to lock; four out of the last five people (with similar problems) that I've advised about this have found - oops! - a loose pin (or, in one case - two)! Do not attempt engage the pins sequentially; do the two diagonal corners first, then the other two corners...

i have checked all 4 pins, no problem there ! As for the TIM application, it was already redone when i returned my system to the local pc store to rule out a ineffective application
anyway, thanks all for the quick reply :)  If there is nothing left anymore to do i leave the system running like it is but if anyone can help
me please send me a message.
