Building PCs since 2009. Eight years in IT support and small-business computer repair before going full-time on writing.

Bio

I started building PCs in 2009 because I wanted to play Crysis on my own hardware and couldn’t justify a pre-built. The first build cost more than I had budgeted, ran hotter than I expected, and taught me the difference between “works” and “works well.” That gap — between specifications on paper and how a thing actually behaves in your living room — is more or less what I write about here.

Between 2014 and 2022 I worked support and small-business repair, mostly Windows desktops and laptops, with the occasional small office network and a frankly ridiculous number of dead hard drives. Roughly 60% of every job was an SSD upgrade and a clean Windows install. The other 40% was anything from corrupted user profiles to a printer that wouldn’t come out of sleep mode for twenty months. I’ve seen the same Kingston A400 480 GB installed in laptops owned by lawyers, retirees, kids in middle school, and at least one professional jazz drummer.

The pattern across all of them: the same handful of upgrades and habits make 90% of the difference, and most people are paying for repairs they could have prevented for $40 and twenty minutes. That’s the thesis behind almost every guide on this site.

What I Write About

My beat at The Technology Pulse is hardware that goes inside or attaches to consumer PCs, plus the practical “is this worth fixing or replacing” questions people actually have. Specifically:
