Anytime i play a Triple A game my damn pc crashed after like 30 minutes . it’s as if the psu gives up or something the screen just goes black and shows “DVI SIGNAL NOT FOUND”

Should i upgrade my power supply? which is what i think it is but i don’t know for sure.

There is no PSU in those specs. What is your current one?

Is your computer completely turning off? Fans stopping, lights off etc?
Or is the video output stopping?

What power supply do you have?

Well fans speed up as if i turned on the pc but the screen stays black until i shut down by holding down the power button

“Two things - 1) Change Power Saving Mode settings in Control Panel - Power, so the system does not time out the monitor. If desktop set to no sleep at all. 2) Change the Sleep or timeout settings on monitor itself.”

Something to think about …

Found this info. while Googling about your issue.

Also …

Have you tried running your pc with just one graphics card? Test that to see if it works that way beyond 30 minutes.

Oh and of course you can use a multimeter to check if there are issues with your PSU.

You might be on to something , I haven’t tried to use my pc with just one graphics card. If that solves the issue maybe i should just sell this other one and play games at a lower setting.

Yeah sounds like the PC is locking up, could be PSU related. If it is an old PSU, not out of the question, especially if it has had plenty of use.

Checking the windows error log in event viewer may yield some info, and might also send you on a wild goose chase.

thanks,

its not an old psu so maybe im going over its limit, or could be the motherboard.

I built something close to your system in PC Part Picker, and it estimates close to 500W.

So I guess that power supply is not overloaded, that depends on how many fans, optical drives, pumps, RGB strips etc you have hanging off it.
If you can monitor the voltages externally, you could tell for sure. If you have a multimeter with min/max function on voltage measurements, that would tell you if a rail is dropping for a short time.

i have like 7 noctua fans , could that be?

11

7 noctua fans, that’s 7 to 7.5W at most if they’re all running full power (based on the 1.08W on the NF-P12’s spec sheet). I wouldn’t worry about that.

thanks so much for clarifying. i don’t jack about electricity lol

Are you overclocking? You didn’t say explicitly one way or another.

Because if you are overclocking, try not overclocking.

yeaH I was but not right now. my cpu oc’s to 5ghz, its so tempting .

15

On a 4790k? Sorry, I’m calling bullshit. That or you really juice the voltage and have an exceptional cooling system, on top of the winningest silicon lottery draw of all time.

16

okay i lied 4.8 ghz but its close enough… and im doing it through basic overclock options on the mobo

17

I have a nice 4790k, and it’s almost stable at 4.8 without extra juice. I can run it at 4.8 usually but it will rarely lock up. 4.7 gets the job done and its perfectly stable. I have the same mobo as you.

Anyway, I’d suggest doing a bios reset and trying again. Skip XMP and overclocking for now until you rule out software issues.
