Computer Completely Freezes, Possibly GPU Issue

[Lammazz]

At seemingly random times my PC freezes completely. It can be whilst playing a game, watching a video or just reading something. The screen freezes and nothing at all moves as if it is a picture, any media such as videos or music stop playing (no audio), my keyboard and mouse can't be used, the lights on my mouse also go out suggesting the usb port was disabled or something. This began happening about a month ago and happens about once every one or two days and the only way to "fix" it is to hold the power button on the computer and restart it. About 3 weeks ago I decided to do a clean install of windows to try and fix the issue and to just clean up my drives, so I believe it is hardware related? I built the computer about 3 or so years ago.
Specs:
Processor: AMD FX-8350 Eight Core Processor
Motherboard: MSI 970A-G46 (MS-7693)
GPU: NVIDIA GeForce GTX 750
Memory: 16 GB DDR3 Dual Channel
Power Supply: 500W

What psu exactly? =maker and model.Ram too ... you can check what ram with cpu-z (freeware) under the spd tab,there's likely a partnr there.

See alot of things that can be the problem.

Two 2400mhz ram is i think too high of a speed for the cpu. Try to run it at 1866 with timings that match.You don't really specify witch ram so can't really say more,maybe just leave timings at auto and lower the speed if it is trying to run 2400mhz now.Look for DOCP or EOCP in the bios,look for a 1866mhz profile and try that.

The motherboard isn't afaik considered a very good one with not very good vrm design which maybe result in overheating of that. Do you also have problems when using the pc with the side panel off? Best would be to point a table fan at it.

The psu isn't also considered a very good series.might well be that this one works fine,but can you test with another one? Maybe from a friend or a local shop ...

The next way gives a decent way to monitor sensors,

download hwinfo32,
install and open it,
check "sensors-only",
click "run".

for cpu temps you'd be better off with AMD Overdrive,look at the thermal margin,the bigger the difference the better.

For better ram specs can you do the next,

open Hwinfo32 =click run (don't check/uncheck sensors only),
close the top window which is the system summary,
in the main window at the left top click "save report",
at the bottom of the next window check "short text report",
after that you'll see what's in the pc,

You could copy the whole of it here by clicking "copy to clipboard" and rightclick+paste in your next respons or just the ram specs.

My ram is running at 666.6 MHz already. I'm unable to test the computer with another psu. The fans in my computer aren't great and I use the stock fan for my cpu. I ran a benchmark for a few minutes with overdrive and hwinfo running to watch temperatures, this is the result http://i.imgur.com/eWNeR0f.png The thermal margin could reach -10 at times sometimes more, plus this is right after booting so over extended use I'd imagine this could rise? When the computer isn't running anything the thermal margin sits around 30. Also included in the image is some information about the ram in CPU-Z.

A minus at the cpu temps isn't good at all.I suggest you reseat the cpu cooler with fresh paste or even better get a decent budget aftermarket cooler for it.A good ventilated case will help too.You already see some cores stay at a lower speed which means throttling.

That ram should be able to run at a higher speed than 1333mhz (666.6x2).

I'll look for a new cpu cooler, thanks for the help.

Okay,seems to be a good choice to me. For the ram could you look at the specs of these and try them in the bios manually,

look at "specs" ->tested speed,latencies and voltage.
