Strange startup behaviour - HELP?!

[RobV1306]

This isn't necessarily a graphics card issue, so feel free to move to the appropriate section of the forum if necessary however I've got some strange stuff going on with my rig on startup which I suspect is related to graphics.

 

Firstly, a breakdown of my rig:

ASUS Prime Z390-P II Mobo

Intel i7-9700K CPU

RTX2070 Super Founders Edition GPU

32Gb 3200MHz Hyper-X Fury RAM

500Gb WD Black NVMe boot drive

EVGA 650GQ PSU

 

The issue is around when I start it up. More often than not, when it boots into windows, it starts off with a really low resolution - like 800x600 - everything is massive and blurry. It'll stay like that for between 5 and 20 seconds. It'll then abruptly cut to black, play the windows "dah-dum" sound to signal something has been disconnected and then bring my resolution back to the proper one.

 

I cannot figure this out!

 

I'm obviously running my monitor hooked up to the GPU only, not the iGPU. I can't help but feel it's something to do with cross-talk from the iGPU.

 

Anyone experienced anything similar? Any suggestions?

 

I'm getting close to going full rage-quit on it and simply re-building the thing from scratch with a clean OS install but feel like this is more BIOS level than Windows.

 

Someone please help?

Do you have the latest nvidia drivers for your card?

Have you tried reinstalling your graphics driver? I seems like Windows is installing the driver every time you boot up again which might explain the hardware disconnect chime and the empty screen behaviour you're getting. Could also explain why it'll be running at 800x600 since it's probably using the basic Display driver.

I probably should have included this in the OP - it did this even when I was running my GTX 1060. 

 

I only installed the RTX card last week and I installed the latest Nvidia drivers then.

 

At first, I thought it was simply an issue with the 1060 but when it did it on the 2070 then I got really confused.

 

This is the reason I'm wondering about some sort of cross talk from the iGPU.

Is it maybe the monitor not being recognized? Is there a laptop that you could test the monitor with?

Yeah, I've actually been using my work laptop with that monitor too and have had no problems. 

 

I've had it suggested that maybe the GPU isn't getting enough power at startup but surely if that was the case I'd simply get no signal. 

 

I'm also thinking that the boot time may simply be too fast for it to initialise the GPU (given it boots in seconds 'cos NVMe). Do you think maybe adding some artificial wait time into the boot sequence would be a good idea?

Considering this, and the rest of your statements, it's possible that you may need to do a full reinstall of Windows.

 

I'd start with trying a different monitor cable, plugged into a different port on the GPU and monitor if possible. (if you don't have another cable, just try a different port with your existing cable if possible) If you're using HDMI, try DisplayPort instead, and vice-versa.

Try using DDU (Display Driver Uninstaller) then reinstall the Nvidia drivers.
