MSI 870A-G54 AM3 motherboard going bad?

[jwin742]

I built my computer about a year ago and I haven't had any real issues with it until now.

I got Battlefield BC2 on Steam and Since I started playing it'll play fine for about an hour to two hours then all of a sudden my computer will completely lock up. I can't do Ctrl+Alt+Del and no matter what I press nothing on the screen changes. The sound basically cuts out when it happens. The only way to get it working again is to power cycle it. I haven't had it do this doing anything besides playing battlefield. I checked Event Viewer and the only thing it mentioned was the computer being shut down improperly.

I've run memtest86 and everything checked out. so I don't think it's the RAM. The Power Supply seems fine too.

Any help would be greatly appreciated.

What have you done to test the PSU?

How long did you run MT86+? and was it the most current version?

I've had a similar experience, and it turned out to be my GPU. Perhaps putting some extra stress on the GPU would cause the lock up to happen faster. Download FurMark. Note: FurMark runs in fullscreen mode and causes your GPU temps to elevate to higher than normal temperatures, so don't be alarmed if you see your GPU at 80°C+. If the system locks up you'll know because FurMark will stop calculating.

If FurMark crashes (which typically will happen w/in the first 30 minutes), you'll see dots all over the screen image. This happens because the data being sent out by your GPU is corrupted. The data gets corrupted because the GPU gets too hot.

I let MT86 run through once and it was the current release.

I posted this question here as well. temperature screenshots as well as additional info.
I'm a little hesitant to run Furmark as I don't wan't to damage anything.

i went ahead and ran Furmark. I have a 6850 though and if I remember correctly they have protection against it. The highest temperature I got to was 77C

Well I played Battlefield until it froze again.
I don't think it's overheating

I had to take these with my phone so apologies for the quality

I tried disabling the audio like it said in the post here EA Forums
and it still crashed like usual.

Anyone got any ideas?

Your PSU is still up for consideration, as you haven't described any testing done to rule it out. But, for MT86+, I would run it again, but this time let it run for at least 8 passes, which will take several hours, so I recommend doing the test while you're away from the computer (like overnight, etc.).

Your 12 volt was showing close to 14 volts???? Is that not out of spec?

looks like a psu... and what temperature software are you using? looks interesting
