Hello Guys,

I have been facing weird things while gaming, here are the faced issues

1) Sometimes the PC freezes (while gaming, i play CSGO with 250fps) and i have to force shutdown the PC to go back to the normal state
2) Sometimes the PC turns off and displays this prompt ( System shut down because Power supply surges detected during the previous power on. ASUS Anti-Surge was triggered to protect system from unstable power supply)

Current configuration

i7 4790
Mobo: Asus Z97-A
Graphic Card: GTX 760 (gigabyte)
PSU: Cooler Master 700W
Memory: 1333 Mhz 6GB Kingston (3 x 2GB) << From old system

I Suspect that the graphic card is the one making issues, or could it be the PSU?

Thanks for your comments.
Yes, after upgrading my RIG, i got a new UPS.
download GPU-Z and post the results when playing
@ironman

What series your Cooler Master 700 W and for how much you have been using it? - Is that occurring on different games - I suspect a PSU defect since that happened with me before ; watch out since unstable voltages will defect the board and the Graphic Card.
@Tech Guru,

well the PSU is called Cooler Master Extreme 2 725W
in fact i bought it used from a guy.

What do you think ?
it is clearly a power issue ( this is why i asked about your UPS first ) but the PSU is also a point of error .
the GPU-z can show you how much voltage and amperage the GPU is taking to compare it to normal value
I will download GPU-Z and monitor voltages and let you know, thanks
in these cases it could be the PSU or some component overloading the rail for some weird reason.

anyway my thoughts on this is that if components are fine then its not a faulty powersupply but rather a lower end one along with overprotective dumb motherboard designed for people to keep spending money, a server motherboard won't ever do this lol

anyway, its just that the system is causing the PSU voltage to wiggle a bit, this happens when the system decides for some reason to stress PSU either during a game or something, but the moment the system stops consuming power the SMPS controller chip lags a bit to regulate the voltage according to new current requirement this is done by a Voltage Feedback Loop which the controller relies on to control the PWM duty cycle and hence the output voltage. so when you are stressing the system the controller senses a voltage drop and immediately increases the duty cycle to regulate the voltage again.. but once you suddenly stop the high load, the voltage OVERSHOOTS for a couple milliseconds just the time needed for the controller to lower the PWM duty cycle. this overshoot appears to trigger your "sensitive over protective OCD asus board lol" to log a power surge, it could be true the powersupply is bad.. but 70% chance is that its just a normal overshoot.

so after all this what you can do 1- check 12 volt rail voltage yourself it should be somewhere around 12 +-couple millivolts, then stress it using a stress test program and suddenly quit it, and see if any visible overshoot, then you can safely disable Asus surge monitor and 2-disable surge protection immediately. if you don't understand what i am trying to say then the guys are right most probably a PSU needs replacement.. i don't want to cause any trouble.
@DNA well i read your post twice (thanks for replying), i guess i will try finding a solution for stress-testing the GPU, and will check if this happens, will post here once i have results.

@Stygmata, yesterday i downloaded GPU-Z and i asked it to write a log file, everything seemed to be normal

concerning turning off Asus power surge protection, i can do it, but i don't want to risk damaging my Mobo and my other components (maybe the PSU is really faulty, or the GPU)

Thanks.

Update: Yesterday i was also in-game, (Power LED was orange), no more output on screen, i also had to force power off the PC and start it again, i am really lost between the graphic card and the PSU!

Can this error indicate the problem?

Appreciate it
If the power light is steady amber — The computer is receiving electrical power, but an internal power problem might exist.
do you have other PSU or GPU to test ?
Yes the power light was steady amber, and unfortunately i don't have any other PSU or GPU to test :(
i wish it would be a PSU (cheaper to replace)
remove your GPU and use the integrated one . then use HeavyLoad to stress your machine .
if it doesnt stutter then it is your GPU .

PS : the system Wattage with your gpu in FULL Stress = 278W
@Stygmata i appreciate your help :)

Well i downloaded HeavyLoad, and i didn't remove the GPU, i did a stress test for the CPU and GPU (at the same time, which was the default setting in the program)
the test was performed for 4 minutes,

Nothing happened.

Thanks.
4 minutes is nothing .
put it minimum for 20 min

Thank you for helping guys, it was "probably" due to a mis-configuration of memory sticks, non similar sticks were installed on the same channel, in all cases i replaced my PSU, replaced my memory sticks, and got 2 similar memory sticks and installed them on the same channel.

Thanks everyone
either way this problem shouldn't in anyway trigger the surge protection it is weird, and yea especially in dual channel mode the RAM should be exactly the same, if from different manufacturer they should have exactly the same chip layout single side or double side. anyway glad it is fixed
