Around 10 months ago, I built my first computer.
Everything was going well, no errors whatsover.
However around 3-6 months later (no sure exactly), In noticed that when I played games, it all depended on the game, the computer would freeze.

Back then I was using a AOC 2047 monitor which when it would freeze caused a large buzzing noise. Now the freezes are the same, but without the noise as i switched to a Dell Monitor.

Help me, I can't play some games due to this issue.

My Build is as following:

GA-990fxa-UD3 CPU
ATI Radeon 6970 2GB
G.Skill (2x4GB) 8GB Ram (F3-12800CL9D-8GBDRL)
Antec VP650P 650W PSU
X- FI audio card (added after freezing to solve audio static in headphones (on board sound)
500 GB HDD

Bluray LG - dvd drive


All the games i play freeze as random,

but recently after playing GW2 (guild wars 2)
it freezes ever 20 minutes.

Thankyou for your time and effort.

Download memtest and check your RAM. You may have a bad stick of ram.

I am running a memtest at the moment.

Could this possible be the reason why the computer freezes without a notice or BSOD?

Just a still image?

A corrupt RAM stick can cause that issue. It should be covered under warranty as a manufacturer defect.

After running memtest for one hour, it showed no errors.

Any other thoughts?

I had a small look back at my build (I bought from pccase gear)

It spoke breifly about a stock overclocked video card (gigabyte radeon HD6970 overclocked)

Is there any issues that could cause this ?

An unstable OC might cause freezing. Download MSI Afterburner and downclock it a bit. See if that fixes it. If it does you could bump the voltage slightly to get back to your normal speed. Or higher :)

Just be careful. Giving it too much voltage (very large amounts, if you stick within 100mV of stock you'll be fine) can burn the chip. Find a guide on OCing the 6790.

What specifically on msi afterburner shoudl i change?

I've lowered the gpu clock from 900 - 800 mhz but still freezing?

What about memory clock? Aswell?
October 21, 2012 9:43:43 AM

Yeah lowered those settings, and im still seeing some freezing..

I wonder what else it could be?

Could it be a corrupt HDD ?

After checking through Event viewer, this error seems to occur prior to every crash.

Any thoughts

1 hour isn't enough for Memtest. It probably didn't even get through all the RAM. It runs a very intensive tes. Leave it overnight.
October 22, 2012 10:09:50 AM

Okay,i'll leave a test overnight tonight,

I'll get back to you.
October 22, 2012 9:37:36 PM

Ran memtest for a lil over 10 hours. Passed ever test.

I have no idea where to go to next?
October 25, 2012 10:02:39 AM

Any more thoughts.. ?
