Where does the noise come from? Did you check the event viewer? Did you recently upgrade any hardware?

The noise you are probably hearing is just the PC freezing which if you're gaming, watching a movie, or listening to music can sometimes put a nasty noise through the headphones or speakers.

Freezing could come from any sort of random issues so it really depends on what you're doing at the time the freeze occurs.

Also extraneous information, when was the last time you've cleaned out your PC, dusted off the CPU heatsink, repasted the CPU heatsink, updated drivers, and searched for Malware/virus?

the computer is pretty dust free, and i repasted the heatsink about 2 days ago, all drivers are up to date, and have not checked for malware or viruses although the OS is a completely fresh install. The noise is just like you said caused by the freezing when im gaming or watching something

Did it do this before you re-pasted the heatsink?

yes it has been doing this since i got the computer, someone told me repasting the heatsink would fix the problem, but it was only temporarily the computer seemed to stay on longer but it still shuts down, i have even taken the graphics card out wondering if it may be a power issue, it again has prolonged the life a little but the computer still shuts down. Maybe i need a bigger PSU?

Do this for me please, locate 450+ watt psu to use or borrow.
Test it for 2 or 3 few days and see if the problem happens again.
If it does please note what you were doing and what time it occured.
Bring back the info you found out.
Once I know that we'll start the rma process or look into getting you a different board.

May I ask what you're specs are ?
CPU-Z provides that info if you don't know right off hand.

Hmm time for a rma service request, call them tomorrow.
Tell them everything that happen state what you tried.
When they ask for the S/N uninstall the mobo look on the back should be a white label.
