Pc shutdown issue

[Diceair]

Hi there

 

Me posting here once again without having my problem solved. 

 

So last night my pc was still running fine. So I went to bed with my pc switched on and only on desktop with nothing else running. So when I got to my pc this morning my pc was switched off with the power LED blinking. So I pressed the power button and my pc went back on as if nothing happened. I checked the event viewer and I can see there was a power failure on my pc.

 

My specs is as follows

 

i7 4790k @ 4.6GHz 1.26v corsair h100i

16GB Adata ddr3 2400mhz set at xmp profile

AMd r9 280x crossfire
Corsair ax 850w

2x ssd (1x gaming 1x os)

2x 1tb HDD

Qnix qx2710 @ 96hz (running 60hz on desktop)

 

I have a feeling it's my ram or memory controller when running at xmp profile or anything above 1600mhz. at the beginning when I got my pc I was having some ram issues (had corsair vengance 1600mhz but different sticks but got that issue sorted) So I decided 16gb Adata XPG v2 2400mhz. Now the issue is that I can play games and do pretty much many other stuff without this happening and this doesn't happen all the time. This is the 2nd time it's happening.

 

The other time I was using my pc normally on the desktop and it switched off for no reason. I guess this sis not a easy thing to test as this happens randomly at times. Maybe I should wait for it to happen more frequently or just ignore it as it's not happening all the time.

Sounds like your PC went to sleep, nothing more. (Flashing power LED = sleep)

Have you disabled Sleep in CP?

Yes disabled sleep but like I said in event viewer I can see that my pc was not switching off properly meaning power failed on it. Also I was using it on desktop the about +-2weeks ago and my pc just switched off. Sound almost like a protection of my PSU  is kicking in.

So no one can help me with this issue?

sounds like it just went to sleep or hybrid sleep. the just turning right off, sounds like a the PSU fail safe. 

not sure what else to say really.

Do you think it could be my overclock or my RAM that's not stable? I also checked and pc is not going to sleep mode ever. I decided to switch back to stock ram clocks in the mean time as I see no benefits anyway for now. I had it failed on me once while I was just doing desktop work so thjat indicates no sleep issue so far. I also did a aida64 full streess test yesterday (GPU,RAM,CPU etc etc) no power issues.

I doubt it could be your ram, but if it stops happening after you set the clock normally, then it probably was.

I also doubt a ram could be the cause of this power issue but the cpu power plug could be as back in the socket 775 days I also overclocked my cpu and cpu power plug went dead so that was the issue.

Its possible for sure. maybe try a different PSU if you can

I think I will have to wait for it to happen again as I don't have another psu on hand to test. I already change my memory to default so doing 1 thing at a time is better.

Indeed it is. Hope it works out

Ok so i had my pc on since I last spoke. Then today I was busy with some stuff and my pc was just idling when suddenly my pc went completely dead with no flashing led lights. Now by just pressing the power button my pc went back on and continue as normal.

 

My biggest problem is that I can do a fulle aida64 benchamrk test (memory,GPU,CPU,FPU, etc) and not a single failure. So how do I go about diagnosing my pc? long time ago my even on stock clocks I couldn't get my RAM on XMP profiles or my pc will freeze. Now i know xmp is not garunteed but still funny that it will only freeze when on idle.

 

If I have a unstable cpu then won't my pc just freeze and not switch off. this indicates a power issue of some sort. I had it connected to a ups and even when on ups it was giving me issues so decided to move it off the ups and still same issue.

 

What I also notice now is my Sound blaster-z is not being detected by the pc.

Your PC is hibernating, check your power profile.

Not hibernating. I alreeady disabled it by going to CMD as administrator and running powercfg -h off

[BlueChinchillaEatingDorito]

Oh damn I remember when one of the PCs I haven't switched on for months started doing that. Got paranoid and decommissioned it.

So, I believe it would register as a power failure if the motherboard was going to one of the many sleep states- there are like 5? S3 S5 etc

 

Check bios to see what sleep states are enabled- if windows attempted to sleep and it went to the wrong sleep state- it would be an error.

 

Also, I don't think there is an implementation- well there is.... but check to see that you dont have one of the mother board manufacturer power saving utilities installed- it could be running in background- forcing the pc to sleep when idle. However- you did say you were using it once and the same thing happened?

 

Perhaps try a hw logging utility? See if the voltage does something weird over time.

I logged a ticket with corsair and they said I must use some sort of PSU tester. The one problem with that is that we can't get any of that here in South Africa.
