Hi Biff,

If you passed Memtest all night, then as Raggz mentions, power may be the culprit.

I know there are some system graphics demos out there, but I have never used them. With some tool like that, I wonder if you could create a heavy load for the CPU and GPU and then see if you experience a similar shutdown?

This comes to mind:

Like I say though, no idea if that would be any useful indicator.

That's a thought. If I get a chance tonight I may run that. Or maybe this: http://www.futuremark.com/

It still sounds to me like the processor overheating. Have you tried running Prime95? That will really tax your processor. Is your CPU overclocked at all, and what kind of CPU cooler do you have?

I am using the stock CPU cooler and I have not overclocked it at all.

I ran Prime95 using the test that is supposed to max the CPU and power consumption and it passed. Looking at Core Temp, the processor never went over 61 degrees Celsius and my computer didn't shut down.

I also ran a benchmark in 3DMark06. It ran fine, here are my results if you are interested: http://3dmark.com/3dm06/16709393



I ran that demo as well. It was kinda entertaining watching thousands of frogs walking around in platform shoes carrying rocks and eating shrooms and then passing out. My PC handled it fine.

Well Biff, I dunno.

I guess you could see about settings maybe? Adjust them up or down, and see how things go.

After my Win7 HDD failed a few weeks back and I had to reinstall, I got the latest driver for my ATI card. Immediately started having graphics glitches in Arma 2. So I went back to an older driver, and things are fine now.

I don't know either.

I installed the latest drivers for my graphics card after I started having these issues. It doesn't seem like the drivers had an effect for me.

I'm not sure what else to do other than wait for the next patch and hope it fixes my issue.

A few days after giving up and waiting for a patch I noticed a strange vibration coming from my PC. I opened it up and saw my video card bouncing around. I took it out and noticed that one of the fan blades had disappeared. So I ordered a new VGA cooler and finally got it installed last night. I am happy to report that I am now able to play Iron Front for hours on end again. Apparently it was a heat issue with my video card. Strange that an overheating video card would shut down the whole machine, but I guess that was it.

Thanks for all of your help! I am looking forward to seeing you on the battlefield.

Wow, never seen that one before!

Glad you're up and running again Biff, hope to see you soon.
