Question Losing connection to displays randomly.

I recently built my first system which went well as far as I could tell.

The only problems I've had are a 2-3 second freeze once every hour or two and very occasionally I lose connection to my monitors. Both monitors lose connection and the only way to fix it has been to restart my computer, then unplug and power cycle the monitors and reconnect them. Any ideas?

Specs are:
Intel Core i7-9700K Coffee Lake 8-Core 3.6GHz LGA 1151
Corsair H60 Processor Liquid Cooler
Asus ROG Maximus XI Hero Z390 Motherboard
Corsair Vengeance RGB Pro 16GB (2x8GB) 288-Pin DDR4 DRAM
Samsung 970 Evo 500GB M.2 NVMe PCIe3.0 x4 Internal SSD
Seagate Barracuda 2TB HDD
Gigabyte GeForce RTX 2070 Windforce 8GB
Corsair Crystal Series 570X RGB ATX Mid-Tower Case
EVGA SuperNOVA 550 G3,, 80+ Gold, 550W Fully Modular PSU
Corsair SP120 Case Fan
BenQ Zowie XL2411P 24inch 144Hz Monitor

** I noted the followed two events last time it froze and I had to reboot in order to reconnect the monitors.

Thanks.

My initial impression is that the PSU 550 watts) is not able to support the current load.

Add up the wattage of all supported components and add 25% more. How close is that total to 550?

There are online calculators that can help you do that. Just try 2 or 3 to determine if there is some consensus.

Then consider that the PSU may not be up to providing the necessary wattage due to quality, age, and condition.

Update your post accordingly.

Hi Ralston,

I was unaware of the added 25% on the required PSU. My system seems to come out at 450-460 Watts. I'll order a larger PSU and see how I go.

Thanks a lot for the help, I'll update here with my results when it arrives.

My opinion,but don't see a reason why it should be the psu. A 550watt of that quality should be more than enough to support that hardware (unless already faulty).

Do you have the latest bios? "Versie 0905 from 2019/04/11" Can look in the bios itself or look at the lefthand bottom quarter of hwinfo,

download hwinfo,
install and open it=click run,
look at the top window which is the system summary,
look at the left bottom quarter
Did you try with the onbaord gpu as well? Means taking the rtx 2070 out.
Does the ssd have the latest firmware? Use the Samsung Magician to check.

Hi Vic,

I downloaded Version 905 of the BIOS to a usb and attempted to load it. It said there was no BIOS file on the USB, but there was an option to update it via the internet. I tried the internet update and it automatically updated, though only to Version 805. Should I try further to install 905, or would the automatic interner option be right? The loss of connection to my monitors has happened again since the update.

I have not tried with the onboard gpu, I'm not exactly sure what you mean by that.

I used Samsung Magician to check and I do have the latest firmware for my SSD.

Thanks again.

The bios file comes in a zip file,did you unzip it before putting it on the stick?

For using the igp (integrated gpu),take the rtx 2070 out of the pc and use the motherboards video putputs on the back i/o to see if you will still get the loss of cennection.

Nope I've gone back and checked and I'm just an idiot. I have no reasonable excuse.

I've actually just been gaming a little and noted that on MSI Afterburner, my Power usage hit 99% at one point, with a fair amount of time spent above 80%. Just going off that is it more likely that the PSU is at fault or am I misinterpreting it?

I don't know if I'll be able to replicate the issue as it only occurs once every 8 hours of active use or so and I don't think I can run the programs I've had running, particularly for 8 hours without losing my mind on just my CPU. I'll keep it in mind if all else fails though.

Thank you!

Guess you talk abut the biosfile, here,is no problem,it happens. Some things you just have to learn.;)

Can you make a picture an post it here?

You can use Imgur to post a picture here,use the "img" link.
Click "new post" ->choose "upload images" -> "browse" ->choose the picture and click "open" ->put cursor on the picture that you uploaded->choose "share links" and copy the img link,paste it in your next post.
Might be the psu,but it is enough for the parts and usually good quality,but even the best psu's have units that can fail.

Hey Vic,

I'd ordered a much larger PSU (750) in the hopes that it would be the problem. Since the problem only occurs every few days it took a while to test. It did not work, my monitors lost display again. I've tried a variety of hardware diagnostics and stress tests for my CPU, GPU and Ram since then with all components passing every test with flying colours. I tried the BIOS update again and I was right the first time, it doesn't seem to recognise Ver905 but rather said it is up to date with Ver805. I'm at a loss for what else I could try. I've researched the 99%+ power of my GPU and apparently it's normal. Just using all of the power it's set to be able to use.

Any ideas would be appreciated, thanks again.
