Pc Randomly Freezing

[Blazedmars]

I just recently built my gaming PC and it randomly freezes so often. For 3 days it will not freeze then after that it will freeze 3 times in a day. I am not that tech savvy. Would appreciate some help. My specs:
Cpu: Amd 8350 Vishera
Mobo: Gigabyte 990fxa-ud3 revision 1.1
Psu: Seasonic 620w M12 80+ bronze
Ram: G Skillz Ares 8gb 2x4 1866 mhz
GPU: Evga Gtx 670 FTW
SSD: Kingston Hyperx 3k 128 gb
HDD: Seagate Barracuda 1 tb 7200
Case: Fractal Define R4 with stock 2x140mm fans
My PC doesn't overheat but I do have no the fans on the top of the case which the CPU cooler points too so I'm wondering if i get fans would that help solve the problem. Currently deciding to get the Corsair Af 140mm fans.

If you monitor all your hardware for temps and voltages, what values do you have (any log files prior to freezes)? Which software told you your PC does not overheat?

What's your OS?

Try poppin' out 1 RAM stick and see how it runs. Have you already ran extensive memory tests?

As stated above, check your RAM one stick at a time and i would also advise re-seating your processor.

I get Whea-Logger ID 19 in windows events.
Yes i can try re-seating my CPU.
What do you mean checking my ram. Like Memtest?
Windows 7 64 bit
My temps are good. Idle temp is 25C and under full load is 60ish C
Also when my PC freezes, everything becomes unresponsive. No Bsod and my fans start to run at higher speeds.

So I re-seated my CPU and replaced my fractal fans with the Corsair AF 140 Quiet edition fans and I am still getting random freezes. My bios is up to date and all my drivers have been updated. Tried Memtest86 and it doesn't recognize both my RAM sticks on it. Says I only have 1 gb in total.

There is your problem. - Reseat these and if it still doesn't work then the RAM is faulty.
