Hey everyone,

I know that a lot of people have issues with systems shutting down during gameplay. I know each solution is different. Some had memory problems, others

graphics cards, still others PSUs. I would just like to know if you guys can help me narrow down my specific issue. Here goes:

When Battlefield: Bad Company 2 first came out, I didn't have problems. My system at the time was older, running Windows XP. I have built a newer system

with the specs below.

<<< System Summary >>>
> Mainboard : Asus M3A79-T DELUXE
> Chipset : AMD 790FX
> Processor : AMD Phenom II X4 940 @ 3000MHz
> Physical Memory : 6144MB (3 x 2048 DDR2-SDRAM )
> Video Card : ATI Radeon HD 4800 Series
> Hard Disk : Seagate ST3500320AS ATA Device (500GB)
> DVD-Rom Drive : Toshiba-Samsung CD/DVDW SH-S182M
> Monitor Type : LCM-22w3 - 22 inches
> Network Card : Marvell Semiconductor (Was: Galileo Technology Yukon 88E8056 PCIe Gigabit Ethernet Controller
> Operating System : Windows 7 Ultimate Professional Media Center 6.01.7600 (64-bit)
> DirectX : Version 11.00
> Windows Performance Index : 5.9 on 7.9

Taken from PC Wizard 2010 Version 1.961

I don't have the older machine. I had given it away. Originally, I had 8GB of RAM in this newer build. I ran memtest86+ and found that one of the chips

was defective. It was removed and the other 3 chips work fine. HOWEVER, while playing BFBC2, my system will shutdown completely at random (I've played

all day, as well as only 15 - 20 mins; Completely random). I thought the defective chip was the problem, but it still happens with the good memory. I

don't have issues with the video card, so I don't think it's that. My final thought was the PSU, based on other people's experiences. Below here I have

the voltages that are listed from CPUID:

I've never used this diagnostic tool before, nor have I ever had to diagnose a PSU before. But, it seems to me, that my +12, -12, +3.3 and -5V rails are

all off. Am I right, and my PSU is garbage? Other than playing games (BFBC2 specifically, and the RIFT beta gave me issues as well), the system works

fine. Should I replace my PSU? If so, what do any of you recommend? My bro recommended this:

Any thoughts on this PSU? Thanks a bunch guys. Tom's Hardware Guide is the best.

Could be a heat problem. I had the same sort of issue with my old 8600gt rig. After I incresed the fan speed it stopped shutting down randomly.

I have all fans running at 100% (or at least as high as the system controller allows me). Here are the temp readings for the processor, graphics card and HD, also taken from CPUID:

-----------------------------------------------------

ST3500320AS hardware monitor

Temperature sensor 0 34°C (93°F) [0x22] (HDD)


I thought these were pretty normal ranges. Although I don't think it's a heating problem, if the fans aren't enough, should I invest in liquid cooling? The overall case temp doesn't rise above 36 - 38°C. Also, what do you think of those voltage readings?

I think it's the processor. Are you running on stock cooling? Have you OC'd it at all? If yes, the processor is probably overheating.

Your processor temps @ 65°C is too high. That could be your problem. According to AMD's website 940 spec page, 62°C is the maximum temp for your CPU. I suggest you look into whether or not your heatsink is properly seated and has good thermal paste applied.

Also, if the voltage readings are correct then yes, they are out of spec. Rule of thumb is all values should within be ±5%, especially the +12V rail. This also might be why you are experiencing random shutdowns. Random shutdowns are usually linked to poor quality power supplies. What model of PSU do you have?

The PSU you linked is way overkill for your system, though it is a good one. A good quality 500-550W PSU is more than enough for your needs. Corsair, SeaSonic, Antec, Enermax are the brands to look for.

I suggest you look first into your heatsink mounting (apply some new thermal compound!). If the heatsink is mounted correctly, the CPU may be faulty or you may want to explore a new PSU. I've personally had an AMD CPU die on me, and the symptom was crazy high temperatures so it is possible.

And finally, I ran across this thread in which some people were having similar problems with the same CPU and chipset you are using. Just something to keep in mind.

Thanks guys. Let me look into all your suggestions and I'll let you know how everything turns out. :)

@repritchett: This is my current PSU. Wasn't too picky about what I was getting. Hard lesson learned. Totally replacing it

I haven't added thermal paste yet. Have to go get some. Just wanted to give you gents an update of where I was with this. Also, the reason why I picked that seemingly overpowered PSU is because I do have a second card ATI card (same model as the current one) not installed. I want to be able to use the Crossfire capability and I figure that this PSU will be able to handle that.

Aprevia PSU's are among the worst of the worst I'm sorry to say.

When you say you haven't added thermal paste yet, you don't mean you have a bare heatsink sitting on your processor, do you??? Maybe you meant "I haven't added new thermal paste yet."

BTW, you can get some Artic Silver 5 thermal paste at your local Radio Shack.
February 10, 2011 3:57:47 PM

Yes, I meant "I haven't added new thermal paste." LOL! I'm not THAT much of a noob. ;) 

That's what I'm getting; the Artic Silver at the Shack. That's a pretty dog, BTW. I love dogs.

Thanks for the help RW. I'll keep you all posted as I progress.

Oh yeah, if you plan to crossfire then you do need some watts. I suggest you look for a Corsair CrossFire ready PSU.

February 13, 2011 9:51:43 PM

Well, gents...

Added AT5 thermal paste. Still getting high temps on the die. Maybe I have a faulty die? Still have poor readings on my PSU. Definitely replacing that unit. Thanks all for the suggestions. Gonna call AMD and ask about their 940s. Maybe there is some recall or something that I can get a replacement. Anybody have good experiences dealing with AMD?

When my AMD processor went bad, they issued an RMA very quickly without any hassle.

My Phenom II ran 59 at idle with stock cooler. Bought a Gelid Tranquilo cooler , now it runs at 42.
February 20, 2011 3:12:37 AM

Ok. Haven't heard back from AMD on my proc, but I've narrowed down the issue to this S*** PSU. The +12V rail is falling off and I think it's going to die soon. I want to thank everyone for putting in their helpful advice. I'm going to get a replacement (after I make some extra cash). And I'm going to bother AMD about those temps. Still kinda hot at 51°C.
