Hey all,

Got a bit of an interesting thing here. Over the weekend I put together a new computer, it consists of:

Ryzen 5 2600
G.Skill Flare X 16GB (2x8GB) / 3200MHz / DDR4 / CL14 / F4-3200C14D-16GFX (Tested Latency 14-14-14-34)
Gigabyte Aorus GA-AX370-Gaming 5
Gigabyte Aorus GTX 1080 Ti Xtreme Edition
beQuite Stright Power 11 750W
Corsair Hydro H150i PRO RGB
Fractal Design Define R6
OCZ Trion 150 SSD 480GB
Windows 7 Ultimate

On occasions it has started randomly when I been on my old PC and the new on turned off (slowly getting it all up and running with programs but sometimes I just not had the time so it been off). It is not happening over night though when I'm asleep, but both Monday morning and this morning when I turned on my old PC, the new one started up as well !? :confused: They not even connected to the same outlet, have an extension lead from the kitchen for the new one.

I tried google but not really found much help there, it did suggest to make sure it not going into hibernate when turning off the PC and it don't, it is set to total shut down. I turned of the power options under 'Select a power plan' as well. Although just come to think about checking the memory and CPU-Z showing this.

Might that be the culprit ?? That is of course if I am reading it right, DRAM Frequency at 1200MHz instead of 3200MHz ??

In anycase, I be grateful for any suggestions as to what might cause the random start up, first time I ever had that happen on a PC for me so slightly confused here.
 
@TheSwede

CPUz reports at half speed, 1200 hz - DDR is double data rate so 1200hz x 2 is 2400hz which is normally DDR 4 default speed .
You'll have to go into BIOS and ENABLE XMP, save and exit

as for it starting when it off byt its self - all I can think of is LAN-ON option maybe ?
Guessing both PCs on Windows 7 Ultimate but with their OWN CD CODES?

Thanks for quick replay ! Have just done that now, and memory went to 1600 in CPUz so guess that all right now then. Wondering if that was the culprit though, or if it is something else.

You can also check in the BIOS that wake on lan is not enabled. That could explain the start up issues, maybe.
Thanks for the suggestion. I did forgot to mention google showed that one as well and those been checked, and set to disable. Also Power on by Keyboard, Mouse and Resume by Alarm are all set to Disable as well.

Two things to check: Wake On LAN in the BIOS - as @GIGA-Man suggests - and the power-on switch on the case.
Now, exactly what you mean with the Power-On switch on the case ?? The only thing I can find in BIOS is 'Soft-Off by PWR-BTTN' which is set to instant.
 
I mean exactly that - the physical switch. Is it working properly?
Ohh opsi. :o But, yeah, what I can tell it works properly. It turns on when I press it without problem, and when I was trouble shooting my way through installing win7 it worked when shutting the PC down as well.

download asus realbench and run stress test for 30 mins, 8GB setting - passes your all good to go- 2400 to 3200 should make a nice performance difference !
 
Your ram frequency is well off, like a mile away..... Simple test, look at your board if there is 4 ram slots, name them left to right 1 to 4.. your ram should be in slots 2 and 4.. so from left, empty slot, ram, empty slot and ram.... if they aint in the correct positions you wont get dual channel

They are in that position. The Ram are labelled in the manual from left to right as 4 - 2- 3- 1 .. and I put the ram at 2 and 1. Although you saying my ram frequency is way off, mind pointing out what you finding strange ?

Done that now and it did not throw anything at me so taking it the ram is ok then ? Highest I saw Afterburner showing the temp was at 61C. Which I am guessing is pretty decent ?
 
I don't think ram frequency should be creating your power up issue, that's going to be something else. If i can suggest a testing method or two, next when you shut the computer down, remove all USB connected devices and see if the system still starts up by itself when you next power on the other system. If no change, again on next shut down, take out of the ethernet cable(again note if the system still auto boots). That will at least rule out some possible causes(windows/bios settings aside) and replugging some cables is a pretty trivial troubleshooting process.

Thanks, I pull the USB before going to work and see how things works out in the evening.
 
Ok a slight update. After having done @t31os suggestion about removing the USB connection (only have one presently, for the mouse) I come home last evening, switched on the PSU (had it turned off since didn't want PC turn on while at work) and nothing happened. After 30 minutes or so I connected the USB mouse back again, in a different slot and it never started itself at all, not even this morning which it has done the last 3 days before. Can it been a faulty USB connector that made the PC restart ?
 
Are you connecting it back in the same place? (case front panel?) I've seen all kinds weird behaviour with USB ports and devices. Do you have other USB devices that are still removed? Add one back at a time and see if the problem starts to occur again.
