Some issues with maximus x hero

Hello everyone!

I’m new in the forum. I’m writing here because I’m desperate as I’ve been experiencing several issues with this motherboard and I haven't seen anyone with the same problem.

I don’t know if the problem is motherboard related or is caused by other component like the PSU. The PC is completely brand new and I’ve build it myself.
The issues are the followings:

- My Monitor screen is going black and on randomly and finally goes definitely black even in BIOS. It’s not the screen as it works well in the former PC. I’ve tried three HDMI different cables and one DVI-I cable. When I used a new display port borrowed from a friend of mine works fine for 1 week without a problem.
I’ve been looking for this issue on the Internet and I’ve seen that a lot of people have the same issue as I have and with any rig, so it seems not to be motherboard related.
Now with a Display port it seems to be working fine. It's been almost a week without monitor screen flickering.

- Interferences with my speakers randomly even when my computer is off. I don’t know if these interferences are caused either by the motherboard, the PSU or by fluctuations in the outlet.
I know that this motherboard have several problems with the drivers but this is different.

- USB 3.0 in the rear ports disconnects all the time randomly my external HDD Toshiba 1 TB. I’m not able to watch a complete movie because it disconnects randomly. It happens the same when I try to download from utorrent. When I connect the external HDD to the front ports (USB 3.0) works properly.

- Drop in general performance randomly. From time to time when I watch movies for example I notice some kind of lag in the images and when I play games as well. It’s very strange. Even when I'm writing suddenly the letters stops and in less than a second they appear all at once.

I think all issues are caused by the same component and all of them are realated with an electrical problem of some kind. But maybe is being caused by software, drivers or even Windows 10, I don't really know it.
I think that either the PSU or the motherboard is causing those problems because of a failure of manufacture.

Does anyone have any clue of what may be happening? Or what could I do to solve the problem?

Is your system overclocked? If not, what speeds are you running at and what are your running temperatures by core?

Hi Snakeyes,

Sorry for taking so long to answer you. I've beeing occupied at work.
Now my system is not overcklocked, right now I have it by default in BIOS after being updated the BIOS to the latest version "1301".
My speeds are running at 800 - 4300 MHz (varying a lot in a second). My temperatures seem to be normal keeping in mind the 8700K is pretty hot without delidding. Attached you can find a image with Core Temp. They are: 33 ºC in idle (at 20 ºC room temperature) and 60 ºC playing at Call of Duty WWII for 30 minutes.

- My monitor screen apparently is working fine with the new Display Port cable.
- I'm wondering if the interferences with my speakers are caused because maybe they are broken. I don't have other ones to prove it.

Try this – download the free software HWmonitor (Google it).
Start the program as soon you restart your computer.
Use your computer as normal leaving the program running (minimized if you want).
Try and see if you can repeat the errors/hesitations etc. during this period.
Now look at the HWMonitor window and identify which items fluctuated substantially between minimum and maximum. Some items should fluctuate like VCore etc., while others like +5V,3.3V,+12V should remain fairly steady with little difference between minimum and maximum.
If there is a problem with your PSU, or an electrical short of some kind it might, I stress might be reflected in the readings.
I would also check the integrity of all connections to your motherboard and if possible selectively disconnect any nonessential peripherals.


Best of luck

I'll try as you say. It'll take me some time to prove it.
I'll keep you informed and thank you so much for your help.

Hi All,

Did you ever find a fix for this?

I'm having what I think is the same issue.

Thanks in advance,
Lee.
