Hello sysnative community,

I've been trying to get this issue resolved for some time now. I've linked below the thread I made in software support with no luck and was recommended to get help in here next.

GPU disappears from Device Manager and I have a Black Screen (monitor not registering,led blinking)

Since then I've now upgraded the GPU from a GTX 970 to a RTX 2070 turbo, but still have the same issues.

Since I've installed the 2070 turbo though it's given me different results, now I can't access the remote desktop software anymore so I can't see the screen anymore to troubleshoot this from the desktop.

Now the only thing I can do is to keep trying to power the computer down by holding power button down to shut off and turn on again. After a few tries, it finally boots up with Bios and goes to OS.



Windows 10 64bit
GPU - Nvidia Geforce 2070 turbo (had a GTX 970 that had same black screen issue not getting signal)
i7-6700
32GB RAM

any help is greatly appreciated
 
What is the capacity of your current PSU? I'm starting to think it may be PSU related. That one rail could be bad. Do you have another PSU you could swap or test out? If you purchase one, get a larger one than you have now.
 
The very first thing to try when a monitor loses signal (after checking to ensure cables are securely fastened) is swapping in a different monitor - preferably from another computer. This is particularly true before taking drastic measures like re-installing operating systems or worse, buying new expensive graphics cards. The fact you were able to remotely access the computer before tells us the computer's power supply was still working.

I don't see in either thread where you tried a different monitor. You need to isolate the problem to either the computer or the monitor itself, and trying a different monitor is not only the best way to do that, but its easy to swap monitors too.

If the problem appears with the second monitor, you know the problem is in the computer. If the problem goes away (or better yet, now appears on the 2nd computer) you know the problem is with the monitor.

If you don't have another computer you can swap monitors with, or don't have access to another monitor, most TVs in recent years support computer input.

Totally, from scratch, re-create the RDP connection,it sometimes fixes those issues with new cards. It has for me in the past.

Thanks for the help, but how would I go about doing this? any info is greatly appreciated. :)

I'm pretty sure the capacity is 410watts. It has a 180w and a 230w bricks and the model of PC rig is a ASUS ROG G20 and is a very tight and slim build. This recently had the Geforce 970 in it when the same issue started to happen before I put the RTX 2070 Turbo in.

I did research before buying the 2070 turbo to make sure it would work in the ASUS ROG G20 and went to the rog.asus forum and found someone that confirmed they installed a RTX 2080 turbo with no issues. I've provide the link below for anyone that wants to take a look.

Hello and thank you for your help! I'm sorry i should've stated that in the description, but after I purchased the RTX 2070 Turbo, I also hooked it up with a different HDMI cord and also a different monitor/tv.

After I installed the RTX 2070 I can't get remote desktop to work anymore and the only way I can get it to power up again is to hard power down the rig. I have to do it more than a 10+ times and I'll eventually get lucky and I will see the bios and it will boot up.

Right now I am in that same situation, so right now I have it in bios and took some pics of the settings i have right now, and will upload the pics on here for you to see. I'm afraid to shut down the pc now because of this issue, so if anyone needs anymore info on this rig (from cpu-z or other programs) while the pc is booted up let me know and I'll report back for you.

Thanks again for all the help it's greatly appreciated. I'm disabled so everything takes much much longer for me to do things so thank you for being patient and thank you for the prompt and fast replies!

I do want to state that the GTX 970 I had in the rig was the GPU that came with the rig when purchased and this issue only started to happen a few months ago. This is the same time I think I started using the Oculus Link. (oculus quest with the special usb cord to play pc games) I contacted Oculus support and they had me give them the info from their debug program or something of the sort and said it was a GPU issue and not Oculus.
 
Delete the RDP connection you currently have and recreate it. How to Clear RDP Connections History in Windows | Windows OS Hub

Before doing anything make sure you have a valid backup of your drive. Or at least create a restore point.

The recommended PSU for the 2070 Turbo is 550 watts. You have to figure in your other peripherals too, fans, lights, hard drive ect. They all need power collectively.

Thanks for helping me I greatly appreciate it. I'll give the RDP a shot and report back!

Just curious why this was happening with the GTX 970 before I installed the RTX 2070 turbo, because the 970 should have enough more than enough wattage so I was just wondering why I was having the same issue with that one as well?

If the RDP don't work, since this is a prebuilt PC rig, what are my other options? Could I underclock my rig so it got enough power? Remove the rgb led lights that are hooked up should lower a couple watts for instance. Thanks again for helping me.
 
Before I do the RDP, I want to mention that after I got my pc to boot up to windows, my remote desktop software (splashtop) works fine, so I'm wondering if the RDP is an issue since it works when windows boots up?

If you still think it would help my issue I will try it, but like I said before I could use my RDS when the 970 was in there, but now with the 2070 turbo it doesn't.

I have my PC on and working right now, but don't want to power it down because of the issue I'm having (if I power it down, I'll probably have to keep hard powering down the pc and trying it over and over and over until it finally works)

Thanks very much for your help everyone!
 
I also wanted to post my exact gpu I bought and posted below. They said wax watt for this card is 250watts.

ASUS GeForce RTX 2070 Super 8G EVO Turbo Edition GDDR6 HDMI DisplayPort 1.4 Graphics Card (TURBO-RTX2070S-8G-EVO)
 
So you are using Splashtop for RDP, not built in Windows RDP?

I use Splashtop as well, it simply works and they don't gouge us like the competition. I have to purchase the Server versions because I am on Windows Server 2008 R2 (getting ready to upgrade to 2012).
 
I doubt you'd underclock enough to significantly affect the power usage enough to matter. If you did that, you might as well stay with the 970.

PSU's are not that expensive but I'd test it before spending the money. I use one of these to test PSU's: https://www.amazon.com/HDE-Power-Su...1_6?keywords=PSU+tester&qid=1582918134&sr=8-6
It will tell you the voltages on each connection rail of the PSU.

As with anything electrical, disclaimers abound. I can't tell you enough to use caution and common sense as you can get shocked from tinkering with a PSU.

 
Sorry for the delay I'm still trying to solve this.

Correct i'm using Splashtop for RDP. Thanks for the advice about getting a supply tester, but the ROG has a special PSU brick so it wouldn't be compatible.

I've enclosed a link that will show you what the PSU looks like ASUS ROG G20 (G20AJ) Compact Gaming Desktop Review ~ goldfries

What I don't understand is if i'm not getting the required watts, how come it runs fine when I can finally get it eventually to boot up? I left the ROG on 24/7 since then, but then I had a power outage and back to powering it down 40 times to get it to boot once.

Any other options if any is greatly appreciated!
