Yep, your PSU may be the prime suspect here, try to check what brand is it.
Secondly, your CPU may be overheating and you would like to check the temperatures. If you see temperature is an issue, try applying a fresh coat of thermal paste, mount the heatsink properly and check the fan is spinning fine. If not invest in an after market heatsink+fan. Good ones are available from Cooler Master and Antec.
If you find your PSU is not of good quality, try getting an 80+ certified PSU (550 watt-650 watt should be fine for your build). Good brands: Antec, Thermaltake, Seasonic, XFX and Corsair.
