[SOLVED] Why my computer screen glitching?

[MrMaji]

Yesterday I bought a new pc, which I self-assembled. below I'm giving specifications.

1. Intel i5 10400F
2. Gigabyte H410 S2 V2
3. Corsair 8GB 2400 Mhz Ram
4. Corsair 500 PSU
5. Asus GT 710 2GB
6. WD 240 M.2

So, my problem is after assembling, when I start my pc to install OS.
I saw glitches on the BIOS menu. At first, I ignored it and Installed OS and all other required drives. But when I restart my pc again, after installing all drivers. I can't even able to see my screen as there are lots of glitches on screen and resolution got changed can't even find Geforce butter on right-click. Also, the screen sometimes going black and pc got freeze.

Can you guys help me out, what actually causing this problem?
(I'm doubting either it's a faulty GPU or either my BIOS)
Will be really grateful if you help.

Thanks for your reply, But sadly I don't have another pc to test the GPU.
And my BIOS version is showing F1 20.01.2021
PSU Model is - Corsair VS500
