Question PC screen gets Pixelated

[Animatry]

So it happened two weeks before. I was attending online classes and then suddenly my pc turns off never to start again. I took it to the place from where I bought it and they told me the motherboard is dead and nothing could be done.
My PC specifications were :

• Gigabyte H110M-S2 Motherboard
• G.Skill 2133MHz 4GB RAM
• Intel i3 7110
• Windows 10 Pro

I had bought it on 2017.
As I am a little tight on money so I had to give up all money I had been saving to buy my 1st phone. I went with the old processor.
My current PC specifications are:

• Gigabyte H110M-S2PH Motherboard
• CORSAIR Vengeance 3000MHz 8GB RAM
• Intel i3 7110
• Windows 10 Pro

Now the problem is after some time my Monitor suddenly turns as shown in the pics.

The motherboard keeps running. And only if I press the restart button it starts working again.

1. I have checked with a technician the Power Supply Unit is okay
2. The VGA cable is okay
3. I have reinstalled Windows
4. I had enabled XMP and selected Profile 1 to RUN the ram at 2400MHz but the problem continued so I disabled XMP again

I don't have any kind of dedicated GPU.

I am new to all these forums. So, please guide me if I should edit anything in this post and what tags should I add.

What memory configuration? Do you have 8GB + 4GB (12GB total) ?
Please show screenshots from CPU-Z - MEMORY and SPD sections.

What video cable are you using? Any cable adapters?

Actually I called someone who repairs PC, he gave me another 4gb RAM clocked at 2400MHz to see if my CORSAIR RAM had a problem and surprisingly it's working fine now. I will test the RAM for 1 more day and see if it's fine and then will try to get my CORSAIR RAM replaced.
