Hello,
Over the last week I have built my new Media Centre PC. Unfortunately, whilst the system was completely stable when first put together it seems to have gradually become more unstable.

The system consists of:

Intel 3570k with Gelid Tranquilo cooler
Gigabyte Z77-D3H
8GB (2x4GB) Kingston HyperX Grey
HIS AMD 7850 2GB AMD Catalyst 12.4 drivers
Crucial 128GB SSD
2 x 2TB Seagate Barracuda HDD (The ones recently at a low price on OEM)
1 x 2TB WD HDD
1 x 1TB Seagate HDD
CoolerMaster Silent Pro 600W PSU
Fractal Design R3 Black Pearl case
Win 7 64Bit Home Premium

The computer was initially built last thursday minus the 7850. It seemed to run fine initially and took over fully from my laptop on saturday being left on 24/7. However, monday when I came back from work I found the computer was turned off, checked to make sure no-one had touched it which they hadn't, it loaded up fine and Event Viewer showed a message saying the system has started from an unexpected shut down. However, couldn't replicate it so assumed it was a 'glitch'.

Tuesday the system randomly froze on the desktop not doing anything intensive at all and then yesterday after installing the 7850 I have had another lockup whilst watching a movie in XBMC a few hours later, it froze and the sound was just in a loop.

I had my 20" monitor plugged into the onboard VGA slot with an HDMI cable to my receiver to display on my TV. These have now been switched to the 7850 although with a VGA>DVI converter for the monitor cable (DVI socket doesn't work on monitor!) and still with the HDMI to my receiver.

I honestly am not sure what the problem is. Originally I thought it was the RAM as the incorrect settings had loaded in the BIOS but I have sinced changed them to the rated settings and the lockup in XBMC still occured since then. I left Prime95 running all night on a toture test and woke up today with the computer still up and runnning fine, does this mean I can exclude the CPU/RAM from possible causes?

As I am using a dual monitor/TV display I have Windows set as an extended desktop on the TV with XBMC just opening up on that. The only other thing I could say is that I left Prime last night with just the monitor attached if that would make any difference whatsoever.

This was my first build in 6 years so am really not sure how to find the cause as I simply can't replicate it. Temps on the CPU max out about 60c when running Prime. Catalyst shows the GFX idling about 30x rising to 40c when I ran 3DMark yesterday. I have done no overclocking whatsoever as of yet. Speedfan also shows all the mechanincal hard drives running at about 30c although this is with the side of the case open (and it did lock up once with the side off).

Can anyone point me in the right direction, as I can't replicate I am really not sure how to go about this.

Any help appreciated.
 
Hello,
What do you mean update graphics driver? As far as I was aware 12.4 was the latest version?

All motherboard drivers etc were downloaded from the Gigabyte site the night before the build last week.
 
Do you have some power saving settings for the graphics card you can tweak? I never really trusted cards moving in and out of power saving modes.

Have you run stress tests? OCCT, Unigine, Prime95, 3DMark, DiskMark, memtest86...
 
I have adjusted the Windows 7 power settings under PCI-Express Link State Power Management to Off but that is the only thing related to the graphics card I could see.

I ran Prime all night, ran Unigine for an hour today, and just ran memtest from a bootable USB and 1 pass no errors!

The problem that really frustrates me is not being able to replicate it. I have just installed OCCT but apart from the power settings (which I have no idea what I should be looking for) it seems to be another test similar to Prime which was run all night.
 
I would uninstall CCC, check if the graphics card is seated properly, and the PCIE power connectors are firmly in place, and re-install CCC. Must be driver / CODEC related.

I looked that up a while back, apparently that is for laptops.
