Screen goes black after disabling CMS in bios

Screen goes black after disabling CMS in bios

Hi, I was trying to enable Secure Boot in bios and I disabled CMS. When I did that and saved the screen just goes black.

I then tried to reset bios by joining the two CLR_CMOS, and the screen is still black After turning it on. 

How do I fix this?

Do you know why you had csm enabled?

I don’t know, It was enabled by default

Remove the cmos battery for 10 minutes or so just to make absolutely sure that it works

Is it possible to fix this without taking out the graphics card? My PC is water cooled and my gpu is in vertical mode so it would be kinda hard to do.

In that case are you sure that you reset the bios properly you don't have to remove the battery if you did

Yes, I’m sure because the leds on my rgb devices connected to my motherboard had a different color than normal.

I can try, but it won’t even boot up windows.

Nope, just a blank screen. What I think may be the reason is that I have a PCIE 4 riser cable connected to my GPU and when I reseted the BIOS, it reverted back to as PCIE 3, when I need to set it as 4. But I’m not really sure if this is the case.

In that case do you have an extra gpu?

When you set up your pc did you set it to PCIE 4? And why would your board default to gen ?

I did set it to PCIE 4. When I think about it, it would be weird for the board to revert to gen 3, but I’m really unsure.

If the board was new and it came set to gen 3 then odds are that it reverted to gen 3.

Usually it's the opposite, the mobo will default to gen4 when everything supports it but if you use a riser you need to force it to gen3.

Why do I need to force it to gen3 when my riser is gen4?

If the riser is gen4 and really does work at those speeds then it should not be an issue.

I will try later tomorrow to replace my gen4 riser with a gen3 riser, then set PCIE settings to PCIE 4 and switch to gen4 riser. Do you think this would fix this issue?

I don't think PCIe speeds or the riser are the issue, if the riser can work at gen4 it'll work at all others. It's if it's not rated as high as the rest that it becomes a problem. 

Can't hurt to try though.

If you don’t think the PCIE cable is the issue, what do you think is the issue?

I don't know, there have been a number of people with the same issue over the past months but I don't recall any of the threads I followed getting to a solution with equipment similar to yours. Some had issues with the GPU VBIOS not running with CSM disabled and had to install another card temporarily to be able to get into the BIOS to reenable it but those were old cards, 30 series should have no problem with that.
