My computer shuts off completely while gaming

[Mrblack761]

This has been only happening in one game in particular. (Project Cars) This also happened to me a few days ago. On the prior incident my old power supply completely died. So when this incident happened again on a brand new psu it leaves me baffled.

cpu: AMD FX 8320 @4.4ghz
gpu: MSI R9 390X
ram: HyperX 2x8gb DDR3 1866
mobo: MSI 970 gaming motherboard
old psu: Rosewill 630w psu green series (now dead)
new psu: Corsair CX750M

 

[Solaris17]

Pcars and that 8320? Did you check temps?

 

[Mrblack761]

cpu temps never go above 55C. I forgot to mention its cooled with a h100i. Now that I think about I did change my RAM recently, could that be a problem?

maybe the AMD guys might be able to help a bit more from that perspective. I have personally had issues with new ram on current AMD platforms so I Personally say that is a possibility. I would run a memtest anyway as you should with new parts. meanwhile maybe an AMD guy can pitch in to discuss mem timings and what AMD likes im not experienced enough with it.

barring any problems with the psu I would say the motherboard is at fault
just because the board had heatsink's over the vrm's doesn't mean the vrm's aren't junk which on that board they are ...
while that board is a 6+2 the components are pretty budget end

I would have invested in a better psu than a cx. A client ive done work for had to have two new units replaced within the same month. His bootloop stopped when i replaced the cx with a bronze evga,, xfx or antec unit. Cant exactly what i replaced it with but it cost around £60-70,and thats pretty affordable imo for a half decent psu

 

[johnspack]

Anyone ask if he's overclocking anything yet? The cx750m, while not great, is probably not the issue.

I think he is.

@Mrblack761 : Reset your BIOS to stock and don't overclock the CPU and report back.

i replaced a CX750M by a Seasonic M12II 750 Evo Bronze (the same that i have in my main rig) for a friend who had instability issues with his computer (and the same setup i had previously: 4690K@4.5-4.6 and a 290@1100/1450)

tho i don't think the PSU is the issue actually (i just hate Corsair's PSU that aren't Seasonic OEM model )

barring any problems with the psu I would say the motherboard is at fault

this or

that ...

either a weak mobo for a 8320 or a OC stability problem (which could be caused by a weak mobo ... i choose a 990X/FX with a strong VRM stage over any 970 any time, i had a 970 Ex4 from ASRock and a 990X from ASUS while the 970 was enough for a Phenom II X4 955 BE stock it was a bit feeble for any kind of OC )

I agree with @OneMoar here. It could be a power problem were the PSU is not supplying all components with enough amperage or voltage and it causes the powersupply to overload and shut off. The motherboard could also be getting hot in the VRM area causing it to fail. Check your system events when it does this and see what error it has. It will atleast show that the PC lost power unexpectedly which you can probably rule out software issues.

If northbridge overheats this issue happens. Some games push PC to limits and Pcars prob does that.

Put a 40mm fan or whatever you have/can fit on your northbridge.

 

[patrico]

yeah three most likey things are psu, temps to high or unstable overclock my 2cents

Aaaand another FX proc on a weak power phase mobo.

That is your problem. For FX you need a very beefy VRM section. Recommended is 8+2 power phase design with quality VRM's and sufficient cooling (heatsink + case airflow) for any kind of overclock on an FX 8xxx proc. You've already had your issues, stop using this combination of processor and motherboard right away and get a better combo, or run stock settings and consider an UNDERclock instead. Gigabyte offers considerably better VRM sections on their 970 chipsets (ud3 for example) but you are best off getting a Gigabyte 990 chipset, those are generally better suited for the FX. Or Asus, but that generally means paying premium for nothing at all except the brand name.

Google 'MSI 970 power phase FX' and you will see you are not the only one.

This is a very common issue with these CPU's... I ran into it also when I first picked up my FX 8350 processor on my ASRock 970 Extreme 4.... The combination of the poor 4+1 power phase and crappy PSU I had would allow the computer to boot up, but whenever it was put underload it would just die...

So yes I agree with Vayra 100% on this.

 

[zo0lykas]

95% that your PSU
CX series PSU are budget, and you owned high end GPU, if you play new game's they need stable power for your GPU + don't forget you OC cpu, CX series is like a lottery, if something wrong hes just switches off, due protect from burning.

in youtube or google you can found lots of video about CX series, how bad they are

SORRY FOR MY ENGLISH

 

[Jborg]

I would 1st reset all overclocks you have going... get the system running stable first.

Is this happening in any other games? Or only project cars?

 

[bug]

I've had that happen to me a while ago and it was the PSU. 750W should be plenty for your system, but just to check try firing up a 3D benchmark and if your system shuts down when you do it.
Alternatively, it could be the mobo, but I wouldn't advise you to change that until you're ruled out everything else.

I agree CX is a shitty product line, but if he just replaced his PSU and continues having the same problems, it is highly unlikely to be a PSU issue. FWIW a CX DOES offer its rated amps on the 12V line unlike many ultra cheap PSUs and a DOA usually just fails right away. 750 watts is MORE than enough for this system even with an extreme overclock, that PSU is just sitting at 50-70% load at full system load. So again, very unlikely.

new psu: Corsair CX750M

Well based on the information, something tells me its still the PSU even though that should be more than enough for your setup. The fact that the PSU on the previous setup died and with the new PSU your getting the same problem could still point to that, however the fact that nothing has changed points to something else causing the issues.

I would do as the others have said and reset your overclocks to stock (Just run the computer completely at stock) and see if it still happens. Then after that if it still happens we will investigate more.

Agreed, I'd guess the VRMs are the issue here too. Especially since he is using an H100i, which means there is virtually no airflow around the VRMs to cool them. I'd be they are overheating and the machine is shutting down.

I agree CX is a shitty product line

The CX line isn't shit, they do the job just fine. Their only issue is shutting down when put under full load in a hot environment. Since he isn't even getting close to 750w, the CX750 is fine.

 

[RejZoR]

The high end units are rated at 50°C continuous operating temperature. Most cheap ones want a lot lower temperatures...

 

[Tatty_Two]

I can't see it being the PSU, whilst I know some think the CX is crap it is still Bronze rated with a single rail of 62 Amps, unless it was faulty on arrival there should not be any issues, especially with power delivery (my neighbour has one and whilst I acknowledge they don't have a great reputation he has been running two 7970's in crossfire for nearly 3 years without issues..... maybe he is one of the lucky ones).................... I vote RAM simply because of the timing of his new sticks with the issues highlighted.

 

[OneMoar]

ram generally doesn't cause a hard power reset unless the sticks are on fire ...

 

[Tatty_Two]

Mine did regularly before I upgraded my rig but I agree it's not common, took me 2 months to realise.

Ran the memtest for approx 2 hours with no errors

I think he is.


@Mrblack761 : Reset your BIOS to stock and don't overclock the CPU and report back.

Before I reset my overclocks im gunna run prime95 for 1-2 hours and I will come report back with results and screenshots.

played GTA 5 for two hours with the system running just fine
