Losing signal when playing games while lights are on.

[armaos.dk]

So I just built a new pc and everything works fine, I have a hue+ with lights rgb fan and a kraken x62 with trident z rgb ram. While it''s on and I play a game after about 5 min it makes a sound like when u plug a new usb in, you know... and shows no signal tho I can still hear the game...

I have tried remount the gpu or putting to different slot, yet still does the same. To get it back on I have to unplug power cable for 3 sec turn psu off and on then turn it on again and start pc, then i's normal again.

I have tried no over clock and battery saver but my p crashes with battery saver while lights are open.

When I close lights everything works fine.

I have the latest nvidia drivers

Helpful notes:
It also says no signal when I put a hard drive or plug smthin in while it''s on
It also goes no signal when I try to change yhe color of lights (sometimes)
The gpu doesn't need psu cable it drains from mobo
Cpu avg temp: 13 when idle 20-30 when playing
Gpu avg temp: 30 when idle 35-50 when playing

Pc components:
Asus z170 deluxe (new)
Asus strix 750 ti (used)
Ssd 250g with fresh installed windows (used)
Idk name of power supply will edit it in if asked too bored opening the pc panel, but it's 700 watts (used)
Rest is just some nzxt cooling fans cpu cooler and lights as well as hue+

Other notes:
I think it might be bad psu cables or box or I'm too far from a wall plug. (It goes trough a ps, speakers 2 tvs then to my pc)
Everything is new except psu ssd and gpu, gpu is about 3 yo psu and ssd is 4+

well ether the PSU is junk or because your going through all that lot before it gets to the PC there is not enough power left in the cable.

Yeah makes sense, thanks for stopping by, I'll rry to remove the tv ps and all that and plug it directly into the wall plug and if that doesn't work (while having power option on high and overclock) I'll try balanced and non over clocked. If that doesn't work again psu is crap cuz 750 watts should be more than enough... :/

Hey, so I checked the wall plugs, turns out the power cable was loose, so power was limited. Plugged it back in correctly and so far its been 2 hours in gmae and no signal lose. Thanks

MERGED QUESTION
Question from armaos.dk : "Pc crashes when playing games then no signal but pc is still on."

Issue:
After playing LOL for about 5 min pc crashes and makes a glitched sound then it loses signal to display and I can only restart it from there (power button)

While being idle everything is fine, crash appears when overclocking and not overclocking, iv tried putting power plan to high and power saving non helped, I am pretty sure everything is fine (hardware) or might be the psu or cables or wall power plug as everything (hardware) is new except PSU GPU and SSD (ssd isnt the issue tho)

I've had simular things but after I changed position in my room and wall power plug, it disapeared, and after 2 days it started happening again randomly out of nowhere.

Some say it might be the ram but I strongly disagree as it is new (5 days old) and I am only using asus optimal overclock wich says it is 22% (in mobo option in bios *model z170 deluxe)

Other usefull notes (I will keep them updated):
pc is fine when idleing
temp is low between 25-35 degrees when gaming and between 20 when gaming (that is for the motherboard cpu and gpu)
my psu is 750 watts but not new, it's old as well as my power cable, its 250 volt but it's old
I have the latest drivers installed for my gpu

Build:
GPU: asus strix 750 ti (no power cables drains from mobo)
CPU: i5600k
Mobo:Asus z170 deluxe
Ram:TridentZ rgb 2 sticks 1416 MHz
PSU unknown but it is 750 watts..(i can open the case and check for the brand name if you want me to)
2 fans 120 mm 1 kraken x65 and s340 elite
hue+ 2 rgb fans and light strips

My theory:
Either the PSU is crap or one of it's cables (can be the power cable from the power wall plug or the powe cable from psu to mobo) or my wall power plug output isnt enough or is bad

2nd theory:
My graphics card is old and cant handle games (but in task manager it never says 100% used so idk)

3rd theory:
I am doomed and I suck at building, please help meh :c

Hey, the issue started happening again even when im idle and sometimes windows are in 400x400 or something resolution and in gray color or sometiems it says no boot device, now the issue happens randomly.
I tryed a different wall plug but that didnt help, I actually think tis my windows now!
