[SOLVED] Computer shut off and won't turn back on after overnight until I unplug and plug back in

[justxchaste]

Hey Everyone,

I built this computer a month ago and it has been running great ever since with very few issues. Recently however after I upgraded my GPU the monitor's display is not starting up after I leave the computer turned off overnight (I will turn off everything i.e the PSU switch at the back and power supply on the wall), the display will not turn back on in the morning unless I unplug HDMI cable and plug back in to GPU and Monitor. The cooling fans will spin but there is no display and the monitor will show "No HDMI signal from your device". I have to turn everything off and unplug the HDMI cable on my GPU and monitor and wait for awhile, plug it back in and it will start.

Seriously not sure what's going on and it annoyed me, I go through a lot of forum and they say might be some problem with my PSU.

Thanks in advance.

Specs:
Windows 10 64-bit
AMD Ryzen 5 3600
ASUS A320M-A
NVIDIA Geforce GTX 1060 6GB (after upgrade)
AMD HD 7850 (before upgrade)
Silverstone Strider 500W PSU

Unlikely your PSU, this looks like a GPU driver/system issue as it is not finding the monitor automatically. Go to your GPU makers website and download the latest driver for your card. if that does not solve the issue you may have to use DDU gpu driver unintsaller as your system may be searching for your old GPU as still the primary. The old GPU driver may well be getting in the way....then reinstall the newest driver again

Also maybe worth runnind a windows update thereafter for any generic monitor driver that might need a refresh.

That being said your PSU while good in it's day is pretty old now and a change would certainly do the overall system no harm.

I must be stupid enough that I can't think of this. OMG thanks for your help and it works like a charm.

Hey mate

Your solution works for me for like a week. But this morning the problem comes back, no hdmi signal from device.

Do you know what’s the problem here? Thanks!

Hi there, did you run the DDU to remove the old drivers? Systems can be fine and then through a win10 update or whatever they start looking for the old driver first again. I would uninstall all Nvidia drivers and then re-install the newest one again. It takes time but worth it if the issue is solved for good.

Yes I did, I use DDU to uninstall AMD driver and Nvidia driver, then reinstalled the latest Nvidia driver.

What monitor are you using?

 

[justxchaste]

Dell SE2419HR, I don’t have any replacement monitor or cable so unable to test whether HDMI cable or monitor faulty.

There is a driver for your monitor from August 2019, and also a Display Manager driver from January this year on the Dell website. Could be that your system is looking for them, well worth a try if you have not already done this.
