Computer freezes up every once in a long time.

Hey guys,

I recently built a computer:

i5 4670k
asrock extreme 3
gigabyte 7950

I have it overclocked to 3.8 with a voltage of 1.1. I ran IBT and OCCT and Prime 95 all for a decent time and it was stable through all of that. However, every once in a while, like 2 weeks, it will randomly freeze up. Like the screen will turn some funny pattern and I have to physically turn it off.

Anyone have any ideas?

Thanks

You oc is so mild that I think it unlikely that it is the cause.
I more suspect some driver issue, or possibly a game that needs a patch.

You think just reinstall graphics drivers?

That would be my first guess.

It is always possible that you have a graphics card that is not quite right and needs to be returned.

then it would be a faulty card, but i would say it's too early to deduce it as faulty. He still needs to test his other components.

How long did you do for IBT? i usually do about 20-30 times to run under high stress.

If I remember correctly I did 20 on highest and it was fine. It doesn't seem like I get this problem under the same circumstances. Once it happened while I was running some cpu intensive physics simulations, but the other time was just when I was playing League which doesn't really stress anything as far as I can tell. I guess I'm just not sure if it's a graphics issue or a cpu issue. It also doesn't happen that often so it's hard to diagnose... I will try and reinstall graphics drivers and see if that helps, but again it's hard to know because it doesn't happen often.

Thanks for all the help btw :)

The fact that upon failure, the screen shows a strange pattern is what gets me thinking about a graphics related issue.

A oc failure gets you a blue screen or just a plain stop.

Could there be a heat issue?

Is your psu of good quality and strong enough?

XFX Core 550W

Pretty sure it is not a heat issue, gpu idle at 37 according to real temp and never goes past 50 as far as I can tell

One thing I just thought of though, could it possibly have to do with gpu sag? The card is definitely not straight, but it's not to bad as far as I can tell.

Best solution

Can you put the pc on it's side to alleviate stress and test that possibility?

Or, perhaps use some supporting ties.

Ya I'm going to try that today and see if that helps.

thanks!
