Greetings everyone, my pc having some problem, when i start to play game, my pc will shut down and restart automatically without any warning, so i install ai suite 3 to control my fans to reduce heat on my cpu, but it still reboots without any warning, so i noticed this voltages +12v +5v +3.3v then my voltages are on normal except +3.3v i noticed it was marked red because it's 2.9v and i assume its bad because its marked as red. It also marked as red in BIOS monitoring section. My cpu, motherboard and ram are all 2 years old since i bought it, except for the psu (really old like we bought this along with the pc bundle last 2010), we only reused this psu from our old pc until we upgraded it which is what i'm using right now. The psu is only a local brand and it's 500w. My cpu is overclocked btw. This kind of trouble i'm having right now never happened before. Thanks in advance 
Should i buy a new psu? (if so, what psu fit to my spec? oh and btw i'm planning to buy Asus Strix RX480 8gb this December)
or just change anything on my bios?
Spec
AMD A8-7600
Asus A88XM-A
8gb DDR3 (x2 of 4gb ram)
PSU local brand 500w
Components:
x4 LED case fans
x1 LED strip
AIO Liquid Cooler (120mm Radiator)
