Frequent Blue Screens on My PC: How Do I Fix This?

[armedfroggery]

I’m experiencing frequent blue screens on my desktop PC, which I’ve had for about two years. The errors occur seemingly out of nowhere, and I’m encountering two types of blue screens:
- Critical Structure Corruption (ndis.sys)
- DRIVER IRQL NOT LESS OR EQUAL
Any guidance on how to resolve these issues would be greatly appreciated!
