PC Display Black, Peripherals Off

[Slottr]

Newly built system, every once in a while (without pressing anything) the system will disconnect itself of any peripherals and all front panel connections (power, reset). LED's and Fans are all still running.

 

My keyboard and mouse dont do anything and my monitor is on standby. Any ideas? Psu maybe?

 

R7 1700 w/ stock cooler (idle 25c)

Asus strix B350-F

GTX 1070 EVGA FTW

16GB corsair Vengeance 

750w G2 EVGA PSU

can you explain your problem better?

is the machine loosing video at the same time the peripherals stop working? and your buttons do not shut the machine off or reset it? your power/hdd leds don't work?

All at the same time, There is no video being received by my monitor, mouse and keyboard lose power and all front panel connections are unresponsive when pressed. But all fans and LED's still run.

Please name us your specs. This way we can try to figure out whats the problem.

sounds like a power issue but check the temps of the machine and make sure it's not shutting itself off

 

check the 24pin cable is seated correctly.

would help to know what power supply you have

Are you overclocked?

 

This happened with my roommate's PC when he overclocked his 1400 to high.  It would randomly do what you're getting there.

Nope not at all.

I would double check cables first, make sure they're properly connected. If you doubt it, unplug it and reconnect it.  

 

If that doesn't work... double check everything is seated properly in terms of hardware.  

 

You could also use another power supply (assuming you have one that's good enough laying around) and plug that in and test with that.

Test all your hardware one part after the other. First start with the GPU, unplug it and put a test GPU in there and see if the problem still exists. Try your RAM. remove one stick at a time and see if it works. Check the temperatures. Try resetting your bios to make sure you didn't mess up any settings. I hope one of this things may help

Yeah Ive already started doing that, problem is, is that it only does with every once in a while - sometimes its after an hour, sometimes after twenty minutes. Gonna be a long day

After a day and a half of testing parts, concluded on that it's most likely a motherboard issue. I've tried two power supplies and two graphics cards in this system and all changes have submitted to the same issue. Wish me luck
