About this step, I'll say:

Every fix is seems like a hope only until the real working fix arrives.

Ok, let's not talk much and get to the main point.

BSOD can be fixed if the faulty hardware is replaced or if any changes are made to it.

Believe me, the first time when I've fixed this problem the main culprit was my motherboard's SATA port.

I just unplugged the SATA port which was connected to my hard drive and connected it to another port on my motherboard.

And Boom! it solved the problem!

Sometimes the BIOS battery causes BSOD. So,make sure to change your BIOS battery when you face errors like this or you see wrong time always on your PC.

Another PC I've fixed that was related to RAM Slot.

Changing the ram slot also solves this problem. unless your RAM is dead

Sometimes faulty RAM speeds may hamper your PC's performance and also cause BSOD.

If you find all this fixes not to be working then be sure that your RAM has problem.

And changing it will fix the issues.

Having the best RAM is like a certificate for no worries.
