Question Black screen on MSI Gt75

[Maria124]

Kubuntu 21.04 was working well for one week. After restart the laptop, it was not going to desktop . So with quick trouble shooting I add nomodest to the grub. After this I got black screen. I can't access the bios. I did some bios resetting with battery swap but still got black screen. Your help in this issue is welcomed.
Things I did:
Ram removed,
New hardisk with kubuntu

On a Gateway P-7811 FX I held the power button closed for 5+ seconds until it powered up then down. Depressing the power button again momentarily the machine started.

I did it and machine started as usual but the screen is black

Do you have any other USB devices connected to your laptop other than your mouse. If you have an external keyboard, try unplugging that.

You did properly slot back the RAM right?

Yes I did

So when has this problem occurred and what were you doing with the laptop before it has occurred? Were you trying to upgrade the components?

It was on during night.In morning some aap were freeze so I restart it. And it was not going beyond MSI logo. I mistakenly change some bios setting with fast boot on, ACHI to Intel and then back to ACHI
