Hello everyone!
The components of my PC:
Asus sabertooth Z97 mark 2 motherboard
Intel core i7 4790k CPU /base clock speed/
2x8 Gb Corsair dominator platinum 2400 MHz C11 memories /2133 MHz at the moment/
Asus strix GTX1070 O8G GPU
Corsair RM850X PSU
1TB WD blue HDD
120Gb Corsair SSD
A few weeks ago i bought an EKWB p360 water cooling kit, a GPU water block, and an extra 240mm rad, to have good temps on my CPU and GPU as well.
(Before i installed the water cooling everything was fine even under heavy loads)
But after that, my pc didn't want to work, restarted under load (no blue screen no lags nonthing, just a restart) even if i played LOL.
After this i wasnt able to start my pc i didnt boot, black screen, no bios, nothing. Only CPU fans were spinning. Then i disconnect the Corsair PSU, and put another one (Artic 750W Modular PSU OEM) into my pc, but with this one, the pc didn't even start.... (i was using this PSU when i was waiting for the Corsar one and it was fine). I checked and realized the Artic PSU is dead
... I don't know how it can happen cause last time i used it, it was ok...
I was so dissapointed, but as a last try i put back the Corsair PSU into my PC and it booted normally....
I connected EK and they said i didn't applied the water block on the GPU porperly, so the mosfets were overheating. I applied the VGA block again with new thermal pads and thermal paste (12W/mK thermal pads, and Arctic freeze MX4 compund, both are very good quality ones). Temps were fine, no air bubbles in the cooling system, but the problem was the same.
And to start the PC again, i switched the 2 PSU-s, Artic one still dead my pc didnn't even start with it... but when i put back the Corsair my PC booted again, so i started to look after another solution. I didnt blame the water cooling anymore.
I was searching on some forums, and some users had problems with ASUS GPU tweak and AI suite (sometimes GPU twek in auto OC mode overcloks the GPU VRM-s too much and that cause a problem and a sfety shutdown to save the GPU, specially when the GPU core temps are very low), so i uninstalled them. I am using MSI afterburner because after the forums its better, and ther is no AI suite on my pc. I reinstalled all the nvidia drivers as well.
After this reinstall, my pc seemed to be fine, i was able to play LOL for hours without any problem.
I was sooo happy.... BUT
Yesterday i installed Far Cry Primal, i started to play, everything was ok, high settings, no laggs. So i thought it should be fine now.
After 20 minuntes, my pc restarted again... same: no bios, only black screen. Before the restart there wasnt any lagg just restart and thats it. Only CPU fans were spinning.
But it was different, because this time i get fed up whit this, and just turned off my PC without touching any components.
Today i came home and without doing anything i just powered it up, and it's working fine, i played LOL. As a last chance i tried Fac Cry Primal again and.... same PC restarted, black screen
If i am just using Chrome, or watching movies, or doing anything what is not "power" hungry my PC works fine.
My PC is 2 years old, except the Strix 1070 (i bought it last october-november), and the PSU, because my old one (Corsair maybe RM650 i dont remember) suddenly died after 1 year...
I hope It's the PSU because i lost the warrany for the GPU after i removed the original heatsink.
I hope these are enough details.
Thank you for the help, and sorry for the long thread.
