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.

First culprit, heat. Get HWMonitor and give us a screenshot.

That 6850 is a little hot on stock. Did you clean out the graphic's heatsink recently?

whoops left my overclock on. I've tried it at stock speeds before and it froze as well.
After roughly 20 mins of Battlefield

Do you have the latest driver for your card? And do you have the latest patches for battlefield?

 

[jwin742]

yes and yes.
Downloaded newest graphics driver this week and I bought Battlefield off of steam this week as well.

 

[jwin742]

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

The HWMonitor screenshot I looked at is showing the 5v rail as being very low.

Please list your complete system specifications.
