i bought this computer(all the components) on October 2013

i know its summer but my CPU case(Cougar Midtower i forgot the name it doesn't matter) has a good ventilation and good fans(Cougar Fans) and all, its not even overheating anyways

My Computer shuts down itself WITH a warming that it will shut down now, but i'm not even playing just random stuff internet surfing etc etc
but now its started to shut down itself WITHOUT a warning and then suddenly the thing shows on
BIOS saying its corrupted now the GIGABYTE trying to install to back up bios and after a few frequently shut downs it finally installed
he back up bios so its running again but then the windows went to recovery startup and then after a few mins of checking the computer shuts downs again
its been pissing me off been trying to find an answer but no luck so far
so i came to this website at Tom's Hardware to find best answers i can get. im really desperate right now and pissed....... oh yeah i forgot this happen alot of times today June 8 2015 before the computer suddenly goes to back up BIOS and shutting down without a warning

I've already checked the wires of my computer its all good

now i'm using my good old buddy my MSI Laptop
 
if the pc fans are shutting down too...your looking at a bad power supply. if your mb in the bios shows the voltage of the power supply check that the 12v rail is holding. if it not the power supply then the mb/cpu is turning off do to an over heat issue. most new mb and cpu if the cpu fan stops moving and the cpu hits a set temp the mb will shut down.
as your mb bios is damaged i would go as a bad power issue. see if someone had a power supply you can use.

The computer randomly shutting down would usually be caused by a flaky PSU but on a two years old system and somewhat decent PSU, that seems unlikely unless the manufacturer dumped a used PSU in your system.

A noisy PSU might also explain errors during boot while checking BIOS integrity.

Today is June 7 2015, so I am a little puzzled about how you can be posting today about a problem that started tomorrw :)
