Weird problem when playing video games.

[Tyler Fretwell]

I am a IT student so you can use technical terms to help me out.

I have a weird problem, whenever I start certain games my computer will restart, no BSODs no Beeps nothing. It basically is like me hitting the restart button.

Before I go through what all I have tried so far here are the specs:
Mobo: P8P67-M
CPU: Intel i7-2600K
GPU: MSI GTX 760 (brand new)
PSU: 750 watt
CPU Cooler: noctua nh-d14
Case: Cooler Master HAF X (new generation)
RAM: 8GB 2-2gb, and 1 4gb stick.
HDD: Random Hitachi Hard drive (I know don't even say it)

So first off by no means this is a heat issue of any sorts HAF X along with Noctua nh-d14 is kind of over kill.
(Also I monitored heats when it restarts and they never go above 50 C)

I thought the GPU and CPU mite be drawing to much power from the PSU so I just did some benchmarks using intel burn test and MSI kombuster at the same time (No crash or restart)

After that of course I thought well hey mite be the driver so I did a brand new (CLEAN) install of the newest driver for my GPU. It still proceeded to restart when I started the different games.

I am kind of stumped currently, the only thing I haven't done is do a virus scan, which I have never heard of causing such a problem but I am going to run a full MBAM scan in safe mode (or off of HBCD) tonight to check.

If anyone has any ideas what it mite be please let me know.

I think it is most-likely the PSU but I don't have a PSU tester on hand, so what do you guys think, just buy a new PSU to test my theory or should I do something else?

Thank you.

I kind of want to say it's your ram.

You have a really... bad idea for a ram setup. You shouldn't mix ram like that.

But unless you have a complete garbage PSU, I don't think you're actually using anywhere near 750 watts, probably only like 450-ish

Remove that 1gb stick or vice vers, it could be your memory like above said

 

[Tyler Fretwell]

No I have 1 4gb stick and 2 2gb sticks the ram is fine I already did an all night memtest no errors

 

[James Mason]

Well the ram sticks might be fine, but having mixed ram can "cause issues" like your having. I'd remove the 1 4gb stick and see if the issues persist.

 

[Tyler Fretwell]

What would cause it to just randomly start doing this? It just randomly started last week (it has been working fine for months)

 

[Tyler Fretwell]

It isn't a new build, it has quite a few hours clocked on it playing games and this never happened.

 

[James Mason]

Well what are the certain games that restart it, and what are the certain games that don't?

It might be a power issue, where your PSU is dying, and as soon as a demanding game starts up your GPU starts drawing too much power and your computer just drops. Try a different PSU if you can, buy at the store, return it if it doesn't make a difference.

 

[Tyler Fretwell]

Wouldn't running the multiple burn in tests at the same time re create the same result?

 

[James Mason]

Not necessarily.

We're just trying to eliminate possible causes here, and having mixed sticks of ram is one possible cause.

 

[Tyler Fretwell]

I just remembered I have 2 4gb sticks in it I used to have 2 4gb sticks and 2 2gb sticks but I removed them a month or 2 ago

 

[Tyler Fretwell]

If it still could be ram I could try it but it's really difficult to remove my cooler
