After updating the platform keys and resetting it without saving the changes I have made in bios, it restarted then gives me a black screen ?

Solution I have tried:
CMOS reset(jump/removing battery)
Reseat ram

Error light:
CPU->VGA->DRAM->CPU->VGA Simultaneously

And lights in Keyboard and Mouse

MOBO: Gigabyte B450 aorus pro wifi
CPU: Ryzen 5 2600
SSD: Kingston A400
PSU: Seasonic S2iii
GPU: Gigabyte Gtx 1650 Super

I can't go to the bios its just No signal

FYI:

https://download.gigabyte.com/FileList/Manual/mb_manual_b450-aorus-pro-wifi_1002_e_190528.pdf

(Do confirm that I found the applicable motherboard User Manual.)

Reference physically numbered Page 22, Item 22 - Status Lights.

"The status LEDs show whether the CPU, memory, graphics card, and operating system are working properly after system power-on. If the CPU/DRAM/VGA LED is on, that means the corresponding device is not working normally; if the BOOT LED is on, that means you haven't entered the operating system yet."

How old is that Seasonic PSU? Past history of heavy gaming use, video editing, or even bit-mining?

My thought is that with all LED's being lit then the PSU may have failed in some manner.

Or it simply could be a loose or completely disconnected power cable.

Power down, unplug, open the case.

Clean out dust and debris.

Verify by sight and feel that all cables, connectors, RAM, cards, and jumpers are fully and firmly in place.

From the motherboard User Manual (Chapter 2, Page 23):

"To access the BIOS Setup program, press the <Delete> key during the POST when the power is turned on.
To upgrade the BIOS, use either the GIGABYTE Q-Flash or @bios utility.
• Q-Flash allows the user to quickly and easily upgrade or back up BIOS without entering the operating system.
@bios is a Windows-based utility that searches and downloads the latest version of BIOS from the Internet
and updates the BIOS "

Start rapidly tapping <Delete> and continue to do so while and after pressing the power button.

Will that procedure get you into BIOS?

@Dejviskapup :

Please start your own thread with additional details about the problem and the problem history.

Include full system hardware specs and OS information.

Make and model keyboard? Try another known working keyboard on your computer.
