I convinced one of my friends to build his first rig so we could play BF4 together. He finally did. It worked great for about a month even though, if you plugged a device into one of the front usb ports, it would freeze. Then it started freezing consistently. It would last about 10 minutes or until he tried to play any media or open too many tabs while browsing. With my help, he has replaced every single piece of hardware so far except for the CPU. When we initially RMA'd his mobo, they determined that the south bridge was faulty. When he got his mobo back, it still froze. RMA'd it again. This time they sent a new board. Still froze. He bought a brand new Asrock board 3 days ago. Same issue. We have also replaced the HDD, the GPU, the PS and the RAM. We have repartitioned the HDD and did a fresh install of his OS (win8) as well. We have replaced the cabling on top of this. He and I are at wits end. I feel that the CPU must be the obvious last piece of the puzzle but I wanted to ask you all if we are missing something? We are lacking another rig with an AM3+ socket to test the CPU. ANY input would be worth its weight in gold to us now. Thanks for any help you guys can offer.

Heres his spec sheet:

Also, we have tried to update the BIOS, drivers all seem OK as well. Once it freezes, we have to manually power down and start back up. Can stay on all day in BIOS without issue.

I would hate to ask, but are you using the right PIN configuration for the front USB ports? Both on the case front and on the mainboard?

Triple checked it. We figured it was due to the faulty southbridge once we found out about that.

This was the other MOBO. Upon further inspection (not sure how we missed this) it doesnt appear that his ram is on the compatible ram list. This rig did run fine the first whole month though. Could this be the smoking gun?

Sorry to get your hopes up, just cleaning up the list for better guidance.

  • What about cooler?
    Have you got CoreTemp running to verify your CPU temperatures, Fan controls, or GPU?

    What are the idle/load temps for the CPU and GPU? Did he enable the XMP profile for the RAM in the BIOS? Has he run Memtest86+ to test for RAM errors?

    He is bringing his rig to my house tomorrow so we can review some of these details Shortstuff. Ill let you know my current findings. But, with the given info, would you say its a safe bet that he should try to RMA his CPU? Im no PC expert. I know more than average but alot of the stuff that is "common sense" for you guys, im still learning so Ill do my best to get that info as long as it doesnt freeze. I did have him run memtest in the beginning iirc and it went ok. We've also tried new ram.

    I guess there's a VERY slight possibility it's the CPU, but I've never seen a CPU cause a freezing problem unless it's overheating. I would focus on the RAM and PSU first. They are the most common causes of freezing issues along with overheating.

    We did try to replace those. Thats why I'm so stumped. The only thing we havent swapped out yet is the CPU.

    The answer was his cpu. Replaced his faulty one with a new one and it works great now.
