Looking for IT help with a miscellaneous computer issue

Hi there, I’m in need of someone who can help with a general IT issue that doesn’t fit a specific category. The task involves troubleshooting software conflicts on my PC, performing a clean OS update, and setting up a few essential applications. I’d prefer someone who can explain steps clearly and avoid jargon. I’m hoping to get a quick diagnostic, then a plan for resolving the problems. Priority is reliability, privacy, and minimizing disruption to my work. I’m flexible on the approach, as long as the work is completed and I’m guided through it.
