Adjusted certain configurations in the BIOS and encountered a black display upon startup.
So I have a system roughly four years old, and I wanted to attempt an overclock to boost its performance. I started by adjusting the graphics card settings using MSI afterburner, then moved on to trying to overclock the CPU. After checking some information, I found that a non-K Intel CPU could be safely overclocked. I changed a few BIOS settings and saved the changes. When I tried to apply them, the computer rebooted but only powered up, showing a black screen afterward.
I attempted a few troubleshooting steps: I removed the CMOS battery to reset the BIOS after unplugging the power supply, and also moved the CMOS jumper to reset it again. After these changes, everything seemed normal—fans ran, and I briefly saw the BIOS screen on the monitor before it went black again. When I tried changing the input ports on the monitor, it reported no input detected despite proper connections.
Here are my computer details:
Operating System: Windows 10 Home 64 Bit
CPU: Intel Core i5 3570 @ 3.4 GHz
Ram: 16 GB DDR3
Motherboard: Asus P8Z77-V LX
Graphics Card: Nvidia GeForce GTX 670 EVGA (2047MB)
Storage: 120GB PNY SSD (Boot Drive) 2TB Toshiba HDD
Changing the CMOS will alter your date and time that must be fixed, but it also switches the main video source to the iGPU. Connect your video cable into the motherboard, then enter BIOS and adjust the primary video to PCI-E/PEG so your discrete graphics card works. Also make sure the operating system's boot drive is set as the primary storage. Save, exit, shut down, reattach the video cable to the GPU, and test again.

I wasn't completely confident about what finally made it work. I connected the video cable to the motherboard, but the screen remained black. Then I removed the graphics card and connected the cable directly to my TV, which allowed me to enter the BIOS. After turning off the computer, I reinserted the graphics card and reconnected the cable, along with the monitor. Everything functioned correctly again. Thanks for your assistance.
