Hello, I recently adjusted some BIOS settings on my HP Z440 Workstation. I turned on Secure Boot and turned off Legacy Boot. However, it beeped five times and displayed a red light, which I later discovered indicates a RAM problem. After replacing the RAM slots, the beeping stopped and everything appeared normal. Still, there was no display output. I attempted to reset the CMOS by removing the CMOS battery, but that didn’t work. My CPU has a Quadro 4000 GPU, and I tried various types of CMOS resets without success. I’m considering using an RX 580 because my PSU is 700 watts.

What prompted you to turn on Secure Boot?
Did it function properly prior to enabling Secure Boot? Not every system is built to support it.

I tried Valorant with Secure Boot turned on. Initially it worked well. After updating my Nvidia Driver for the Quadro 4000 via optional updates, the screen went black during boot into Windows. Safe Mode was also unreliable, but I resolved it by skipping the update again.

Disable Turn SecureBoot and observe if the system boots correctly once more.

The screen isn't displaying anything and I can't access the BIOS. Trying to reset the CMOS or remove the battery didn't help.

Ensure your screen is set to the right input.
If using DisplayPort, there are two ports; switch to another one.
Test with a different DP cable.
Check if a DVI cable works and displays video.

I've encountered the same issue before, do you have any answers?

I'm considering purchasing an older GPU such as the GT 210 or 240 to test it out. I saw a similar post and am just holding off on buying it right now.
