While "PC Support" as a topic area might seem extremely specific and limited, the truth is quite the opposite.
I keep a list of general ideas for future tutorials and troubleshooting guides but on my last look at it, I'm pretty sure I'll be writing about fixing a problem with the software on your recreational Mars vehicle before I get to all of it.
Which brings me to my question:
What do you want to learn about?
I'd be happy to put some extra effort into an area that my current readers are interested in.
For example, I've written a lot about passwords, troubleshooting error messages, and a lot of other topics, but very little about defrag software, the BIOS, speeding up your computer, Remote Desktop, SSD drives, physical computer cleaning, and tons of other things that I know you're interested in.
Let me know in the comments! I'd love to focus on a computer-help area that my regulars are interested in.
EDIT: After several comments, I see I should have been a little more specific. I'm looking for general topic ideas, not very specific computer issues. Those sorts of things are better asked over in my forum. If I, or one of my forum admins, starts solving a specific issue over and over again, then I'll write a troubleshooting guide for it.
