Monitor goes to sleep after BIOS/MOBO splash

[hayze]

Computer Specs:

MOBO - ASUS Sabertooth X58
CPU - i7 950
PSU - Corsair TX 750w
GPU 1 - Gigabyte 1080 ti
GPU 2 - Gigabyte 1080

First off I'm not trying to run sli, I know I'm not able to with these two cards.

My problem:
I start up my computer everything starts to boot normal, but the moment it wants to boot from a device my monitor just goes to sleep.
Inside the BIOS it shows SATA 0 and 1 not detected, but the MOBO knows it's there because one it shows both the drives on start up, and two I can select them from boot menu. Now it does show my CDROM AND Blue ray drive, but even then I can't boot to my windows disc screen goes to sleep, even when I try and boot linux from a USB device screen goes to sleep.

I have looked through my BIOS for settings but nothing in that I would change to my knowledge
I took out the CMOS battery, didn't do anything.
I tried using one card at a time, still nothing
My monitor works properly (using it right now on my main rig)
I can't use onboard graphics due to the fact my motherboard doesn't have that
I also can't use my old card, some old card that's $30 so I could hook up my monitor (has no dvi or vga ports) with HDMI, but I no longer have an HDMI cord.

Thanks

Try resetting the BIOS to the default settings. Then manually set the the system drive to the top of the priority list. Then exit saving the settings.

If you do not have an installation disc, download an ISO disc. Then you can use that to repair the start up settings. Or you can do a Repair Upgrade of the operating system.

By the way, I think that you are experiencing black screen. The system would have to get into Windows before it the monitor could go into sleep mode.

Well I tried that all that a second time
I went to my motherboard manual said to remove the battery then move the clr switch to pins 2 and 3 for 10-12 sec, then replace the CMOS battery.
started up the computer loaded default settings.
Then I set it to boot from my CD drive since I do have my windows disc, and after selecting that it still has my monitor go to sleep.
I even unplugged the HDD that has windows 10 on it (I have an SSD i want to put windows on) and have CD drive as first priority to boot from, still monitor goes to sleep, i even pressed F8 to select boot device and my monitor still goes to sleep after I select CD drive.
This also happens when I put my USB in that has an ISO file for Linux.

I do have ASUS EZ flash 2 which lets me update the BIOS to the most recent version through a USB. You think that might help?

*update*
I updated the BIOS and that still didn't help

Any other ideas?

I think that it is probably not associated with the normal sleep function of the computer or monitor. That is controlled by the operating system and is a power saving feature. This is probably associated with the power supply (perhaps it is no longer able to produce enough watts and the graphics card shuts down). Or the motherboard is defective.

Here are some troubleshooting checklists and also some instructions for breadboarding the motherboard.

Sweet I really appreciate all the information

So I decided to go out and buy an HDMI cable for my smaller video card (Nvidia geforce 210), at first I had issues of it freezing when trying to load windows or even when i got to the logon screen, but I successfully got my PC to boot up all the way.
With that being said, do you think the power supply can't handle both of them? I mean I even tried just using one card and didn't work.
My old system use to run a 770 until I got green fuzz on my screen =/

The recommended power supply for a single GTX 1080i is 600 watts. For both cards, I would recommend a 900 - 1000 watt power supply. I don't know how old your power supply is, but they do degrade over time. So even if it is rated at 750 watts, it may not be delivering that much.

The GTX 210 by the way has a system requirement of 300 watts.

Yeah my 750w is 7 years old. Probably definitely is the PSU because both cards individually ran fine in my main rig, finally had time to test it out.

What PSU would you recommend then? I was looking at these two

I am more of a Seasonic fan.

It is more money, but this is another great choice.
