Okay, so i posted here 2 months ago about my problem with Newegg. The first time I got a defective motherboard so I sent in for RMA. And now I'm lost with two more problems. My pc will start and at random times it will shut off completely, no warning and no blue screen. (as if the plug was pulled). And if it doesn't shut off, I will surf for around for a couple of minutes and it will freeze for ten minutes and return back to normal, but then after awhile it will shut off.

Computer Parts:
Cpu - AMD FX-6300
Gpu - MSI R9 270X GAMING 2G Radeon R9 270X 2GB
Psu - EVGA 500 B 80 PLUS BRONZE Certified 500W
Mobo - ASUS M5A78L-M LX PLUS
Ram - Crucial Ballistix Sport 8GB Kit (4GBx2) DDR3
HDD - WD Blue 1 TB Desktop Hard Drive: 3.5 Inch

Things I've Done
- I did a memory test - OKAY (No Errors)
- Hard Drive Test - OKAY
- OPened up the case (no dust because it's only 2 months)- OKAY
- Idle Checked the temperatures - VERY GOOD (GPU - 25 Celsius, CPU 30 Celsius)
- Gamming Checked the temperatures - VERY GOOD (GPU - 45 - 55, CPU 50 - 60)
- I've checked the wires to see if they were loose.
- I've checked to see if the fans were spinning.

Can anyone give me some insight on what the problem is?
