MacBook Air Major Booting Problem, help needed ...

MacBook Air 11-Inch, Late 2010

Processor - 1.6 GhZ Intel Core 2 Duo

Memory - 4 GB 1067 MHz DDR3

Graphics - NVIDIA GeForce 320M 256 MB

OS - macOS High Sierra, Version 10.13

I have tried safe mode, did work initially and then stopped working. Now, latest, safe mode makes the progress bar move to almost the end, but stops and reboot loop continues, or I get a white screen with green and red dots scattered, or a black screen, or a black screen with green and red dots scattered, or a blue screen. I have tried recovery mode, which also worked well at first, and used disk utility to repair disk permissions, after which it would work and boot just fine, but soon enough the problem starts again and I had to try recovery mode repeatedly and use disk utility to repair and make it work normally again for a day or a few days. Recovery mode later on slowly didn't work often, and Now recovery mode doesn't work at all. Tried SMC and PRAM resets which worked sometimes, and now aren't working. As a last resort I have also tried to reinstall the OS, and the problem didn't stop, I erased the drive and internet recovery happened and the original mountain lion OS was installed and I updated to Sierra again, only to again face this problem soon after a few days of using the macbook again.

Recently I used the OS recovery/reinstall flash drive given along with the macbook, used to boot into it and performed repair disk permissions in the disk utility again, after which its booting normally again, but not always. Booted fine once, reboot loop again and then now luckily its booted normally again.

Now even the USB provided isn't booting, it loads to a black screen, or loops again. Later I saw some post suggest Verbose Mode, (Cmd+V), I tried and it worked a few times surprisingly. And now even that fails, and gets stuck at some point.

Me booting my laptop successfully involves repeating all the above procedures or one of the above a LOT of times, and one in 50 times or so it manages to boot and I immediately run disk utility to repair the disk and back up all my content. Now Disk Utility Repair also isn't successful each time, and fails to boot the laptop next time as well.

Recently I ran the disk utility on the main container disk of my SSD, Apple SSD TS128C Media and It interestingly gave me this result that I have attached as a screenshot. Please take a look.

What should I do?

Sick and tired of this problem, I have a feeling that the problem is with the hardware. Do I have to replace something ? Or is there another fix ? Or should I dump the macbook ?
