This kind of error point out highly "power supply" problem. If you provide more details related to when the problem occurs(which program running what are you doing etc) this can speed up diagnosis process.
But if this problem occurs when your PC attempt to hibernate or sleep, then your problem is because the size of the hibernation file (hiberfil.sys) size is not large or big enough to save and store current contents loading in the system RAM or memory.
You can easily fix this;
1-Open a command prompt window with elevated administrator privileges. 2-Type the following command and press ENTER:
powercfg /hibernate /size 100
I hope it helps...
