BSOD Issues - Need help with how to troubleshoot

[n0aH]

Hello : )

It has been quite some time since I posted here (years actually), and I am hoping you knowledgeable people can provide some guidance with an issue I am having.

I have been getting random Blue Screen of death restarts on my desktop for about a year now, and would like to know how to go about troubleshoot it. The error code the BSOD gives is a generic code, and only searching says to simply reinstall windows, which I did and that did not resolve the problem.

The error (STOP) code that the BSOD gives me is 0xc000021a.

Also, I do not get this issue when I am simply browsing the internet. The last two times this happened I was

1.) Browsing the internet and listening to music at the same time.
2.) Installing a game on steam

My Computer is listed below.

OS: Windows 8.1
Processor: Intel Core i5-2500K 3.3 GHz
RAM: 16GB Corsair
Graphics: AMD Radeon HD 6900 Series
SSD: 128GB Intel
HDD: Old 1TB Seagate drive

Please let me know if you need any more information, and how I can start to troubleshoot this. I don't want to have to buy a brand new computer because of this issue, but I don't know how to narrow this issue down.

Thank you all so much!

^^ It seems like there is a hardware issue here, because this issue has persisted over the course of 3 OS installs ( Win7, then Win 8, now Win 8.1).

I am more looking on advice on what steps to take on how to troubleshoot the hardware to determine what piece is causing the issue. Thank you!

Isolating pieces of hardware is about the only way to do that...
