Hello!

It's been long time since I was messing with hardware, so I wonder If someone can help me figure what's going on

It started some time ago. Once for couple times when I try to awake my pc, keyboard or mouse seemed to be off(no backlight) and pc doesn't awakes from them. When I hit power button, everything started(except kbrd and mouse) and monitor got no signal. Lately, I started getting artefacts on chrome(http://i66.tinypic.com/j90mj6.jpg). It's strange because my system (win 10) is perfectly stable(didn't get any bsod or freeze). I tested everything in everyway I know. Memtest, furmark, occt, games - system is stable and on low temps, no data loss. The only thing I noticed, hdtune shows "(C7) Interface CRC Error Count" on every drive(have 3). I know it's mostly caused by a cable but not 3 cables at same time. So, since rig is stable I assume mobo malfunction but It's only me guessing. I would like to take it to service but since I mounted it on a wall...

No visible damage.

My rig:
CPU: 4690K@4,5GHz | MOBO: Gigabyte GA-Z97X-GAMING 3 | RAM: BALLISTIX Sport 4x4GB 1600MHz
PSU: SilentiumPC VERO M1 600W | A/C: Arctic Freezer 7 pro | GPU: Asus Strix r9 380OC
SSD: Samsung 850evo 250gb | HDD: Seagate ST2000DM001, some TOSHIBA
SCREEN: Samsung S27D590 | CASE - HandMade | SteelSeries Rival + Logitech M310, K520
 
No sense to start looking elsewhere until that Craptium PSU is replaced.
In fact wouldn't even try to use that PC before that.

Both reviewed samples died because of being overspecced for components:
http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story4&reid=437
Actually there's no voltage monitoring for 12V (or overtemp protection) because they used cheap ass monitoring IC!
And obviously cheap capacitors, with likely inadequate speed fan to keep them cool.

= Designed to fail and seriously risk PC's components.


These will outlast every part you have there, except maybe case.

Or if you want to update to some of the higher power consumption graphics cards.

Remove OC from CPU, removed OC from GPU.

report back

EDIT - could be worth downloading latest graphics drivers, uninstalling current ones, then installing the newer ones
 
@EsaT I don't buy it mate! Dunno why you show up with the one negative review while all others are positive. But hey, you missed one detail. Other components don't make psu even warm! So thanks but no thanks for telling me to throw away psu, not knowing if its really fault or not.

EDIT: Almost forgot. My psu looks slightly different than the one tested from your link. I gues, it was revised.

@new boy Already tried stock settings. I OC gpu manually only while running games and keep all drivers up to date.
 
If I didn't say it straight, my bad and I'm sorry. All my parts have warranty, so my goal is to TEST i FIND OUT what's fault so I can replace it w/o spending extra money.

That kind of advise is like "I' got VW Passat and the engine sometimes won't run. -What, a passat? I wound't even sit in this crap. Buy BMW, you'll be happy." So If I do throw my crappy psu out but the problem stays, would anybody give me money back? No?
Now can we talk more seriously?
 
It's probably the PSU, after having the warning if it kills your PC I would have no sympathy, I've lost a R9 290 due to a G2 1000w going off and I didn't even skimp on the PSU.

If the GPU is getting bad power it'll be giving you those artifacts and all the other issues you are experiencing, you know that PSU isn't the best so you should replace it to rule it out and protect from damage.

Would you buy a car basing to review looking only shiny colour and polishing?
Big part of reviews aren't any better.

Lack of protections in PSU's main rail providing power to most of PC's components would be serious deficiency...
Even if PSU otherwise performed up to advertising and had good components:
There's no absolutely 100% fail safe to PC's components PSU, but lack of protections simply rises risks to entirely different level.

Letting that kind thing through shows brander's disregard for quality: Overvoltage protections aren't voluntary, but required by ATX specification!
So technically there would have been basis for ranking that PSU as full failure.

Maybe that flaw has been corrected.
But that may have been done by cutting corners/saving elsewhere.
Brand not being eager to offer reviewers good look of PSUs isn't the most promising sign for dedication to quality.


I've myself had things fail because of cheap construction/parts and neighbour even had two PSUs fail:
Sonata II's bundled (in)famous übercrap Fuhjyyu capacitor SmartBomb lasted awesome five months before popping.
Then "standard" quality capacitor PSU developed (cold) boot problems in 3½ years.
At that point it was time for no cheap parts policy.
Myself having bought 80+ Gold PSU month or two earlier had previous PSU unneeded. It's now over 11 years old and still in use.

Also his previous 20" LG L2000C-SF would have soon started showing problems, if it hadn't been replaced by my previous (re-capped) LG W2600HP few years ago.
After re-capping that 20" LG went to my father to replace 17 years old Nokia 449Xi CRT.
For comparison my last CRT, Samsung 959NF, started having capacitors fail after six years.

Ok, I'll replace it with the old one and be back after some time testing.

Swapping parts to bracket location of cause is only 100% sure way.
Unless there's flames and smoke coming out...
http://www.theregister.co.uk/2012/11/26/exploding_computer_vs_reg_reader/

Though in case of that neighbour it was easy to guess correct cause to "muffled pop when pushing power button" in first time.
I even told him about unreliability of that bundled PSU when helping to choose parts.
And then to cold boot problems, which are one of the typical symptoms of failing capacitors in any kind power supplies.


Motherboard "tiring" to load from overclocked/overvolted CPU would be one possible cause for various errors/crashes.
But after "capacitor plague" mobo makers got lot more attentive to capacitor quality.
(school friend lost one motherboard for AMD Palomino to that)
So my primary bet is in questionable quality PSU.


At least nowadays PSU review situation is lot better than 10-15 years agowith more than couple sites doing actual load testing.
I remember how one Finnish site "reviewed" this same Qtec giving it OK good rating, because it was able to power 150-200W load without blowing up:
http://hexus.net/tech/reviews/psu/1359-hexus-psu-power-supply-unit-roundup-taoyuan-2005/?page=19
Though most sites still don't give much thought to prospects of PSU to have long usage life and many "reviews" don't even mention capacitors.
 
As I said, did some testing.
I connected only mobo and ssd. Then I set original multiplier to cpu and did a lot of asleep/awake. I've got to admit, I started to be convinced about psu fault. But then guess what happened... Fans spinning, mouse leds light but no signal on monitor and no keyboard backlight. I would really want it to be a joke. You also may doubt my words so... https://youtu.be/3nJ7_jfn75g

Now why did I suspect mobo in first place. It is mobo that manages power states of psu and delivers power from psu to peripherals like mouse and some power via pcie to gpu. Another suspected thing is sata errors.

Even if the motherboard is to blame that sup par PSU probably killed it, I'm not going to bother replying to you anymore as you seem like a troll, I really hope it goes bang and burns your PC.
 
Better be careful where you move legs under the table with that PC...

How old is that PC/motherboard?
One thing to try might be replacing "BIOS"/RTC battery. (at least it's cheap try)
That battery going empty can sometimes cause totally crazy symptoms you wouldn't think to connect to it.
My first ever PC didn't recognize floppy drive as first symptom...
While at next boots it couldn't anymore find HDD and booted only from floppy!

Only control motherboard has to PSU is telling it to operate by grounding PS-ON wire
And if motherboard fails to do that PC doesn't even boot or PSU and PC shuts down.

After getting PS-ON signal PSU starts and then after stabilizing voltages gives "power good" signal initializing motherboard's POST process/boot.
(that signal does in no way tell about ripple, because PSUs don't have monitoring for that)
 
I bought mobo and cpu on 2.2016 so it's not so old.
Battery and voltages was previously measured with a multimeter. I a meantime I managed to get myself some other crappy mobo so I can finally send mine for repair. Thank you @EsaT for help, I really appreciate it and would really love to send psu instead mobo.

Have a nice evening.
