New build randomly crashing

So I recently built a computer from the ground up ($500~ minus the monitor and RAM) from an old computer. In other words, I bought the parts one at a time over about a month. I put them into the computer, ran it for a few days, and then got another part, eventually completing the build. But right after I installed the motherboard and CPU, my computer started randomly freezing, which requires a hard reboot to use computer again, or crashing and automatically rebooting (has been crashing for 3~ months now). And by random, I really mean random: anywhere from 1 minute inbetween crashes to a couple days. One time, it crashed, instantly rebooted, and then crashed again so fast that it didn't even show the BIOS startup logo.

 

It is a 64-bit operating system with Windows 7 Professional.

Specs:

AMD FX-6300 6-core Black Edition (overclocked to 4.1GHz; problem still persists at stock speeds)

CoolerMaster T4 Heatsink with dual 120mm fans

Sapphire R9 280 Dual-X 3.0 GB (overclocked; problem still persists at stock speeds)

Gigabyte 970A-UD3P ATX Mobo (BIOS Version: F1, latest)

(don't know brand) Generic 1 x 8GB DDR3 RAM (3+ years old from a pre-built HP desktop)

Brand new PNY 240GB SATA III 2.5" Solid State Drive

Solid Gear BASIX Series 600W

Basic optical/CD-ROM Drive

Corsair Carbide Series Spec 01 ATX Mid Tower Case

 

Crashes are slightly more frequent when playing a game. However, I triple checked all temperatures, and without overclocking, neither the CPU nor GPU core even come close to potentially overheating. CPU average temp under load: inbetween 40-50C. GPU Core under load: 48-53C.

it might be the psu is it 80 plus certified?

This is generally not a power supply case. When a psu goes out it's usually all or nothing, not really a freezing thing. Have you checked your event log? Control Panel>Admin tools >Event viewer. 

If you can't find anything in there that could cause the issue, start with process of elimination. Run a mem test> if it passes run everything at stock speeds with minimal things attached to it. no extras keyboard mouse monitor and network. if still failing pull it from the case and try it outside the case on a "motherboard box" bench.

The event log isn't any help, other than saying that the system had an abrupt and sudden shutdown. Doesn't say why :P

I am currently running memtest86, and it has made it through 2 passes with no errors. I doubt it is the RAM since there is only one stick, but I will definitely look into it.

That last idea is a strange one, but I'm curious: what would that do/prove?

Sounds like RAM to me. Seeing as you don't know the name of it, are you sure you're using the correct settings?

It's not a race to the bottom.

Aha! According to MemTest86, it says that this specific model of RAM is currently set to run at 800MHz. However, after a bit of googling, the speed it is supposed to run at is 1600MHz. Does that mean anything? If so, how would I go about changing that?

The model number is Samsung M378B1G73BH0-CK0

800 Mhz is 1600. Just hasn't taken the double into account (DDR)

Check your motherboards manual how to adjust the RAM timings and speed. It's easy work, but each motherboard is different on where they place it. It's a 5 minute job once you know where to input the settings.

Do you know what settings to change and what to change them to?
