System freezing randomly

[Anominity]

Hey guys.

Having some issues with my PC lately whereby it freezes sometimes for around 10 seconds, sometimes until I hard reboot.

This only seems to happen in the latest or more graphicaly intensive games (CoD MW2, Far Cry 2, Batman Arkham Asylam are the three it seems to happen in the most) Now, I normally run these on my 32" 1920 x 1080 TV, and this is where I experience the problem the most, as last night I ran Far Cry 2 for a good 5 hours on my 22" 1680 x 1050 monitor with no issues.

Is it as straight forward as saying my graphics card is unable to handle the higher res (This only started happenning recently, I was running Dragon Age Origins, Borderlands etc fine on the TV before)

I have updated my ATI drivers to the ones released on the 17/11/09 (Not sure the actual version as am at work now) and the temperature of my graphics card is usually at 45 - 50 degrees normal 55 - 60 at load, so it can't be overheating.

So I have deduced from that that my card cannot handle the higher res, but I would have assumed that the symptom for that would simply be a lower framerate, not a complete system freeze?

Ideas? Anything else that could be at fault?

Northbridge or Southbridge temps? They can get quite toasty on Nvidia chipsets.

Does CoreTemp report those temperatures?

No, I don't think so. try everest.

Or try touching the heatsink be warned though that if it is getting warm it could be 70deg.

get speedfan. it should show an ioh temp

Screen freezing problem is usually due to bad memory.
It can be the RAM or the graphics card memory. Run a memtest and see if the RAMs are working fine.

Run OCCT and keep an eye on temps during the test.
And be confirmed that no comp will freeze if the card cannot take the load of the game unless its a ancient card and a recent game.

I've got almost the exact same problem, is there any way to test the graphics ram
