Building computers has always interested me, but I'm not sure where to begin because there's so much to learn. I currently have a prebuilt PC that runs surprisingly hot—around 80–90°C on the CPU and about 80°C on the GPU during many tasks—and troubleshooting it is what motivated me to learn more. I also have two older spare PCs that I could eventually practice on. Are there any beginner-friendly guides or a good learning path you'd recommend? I'm nervous about damaging something, so I'd like to understand the basics before taking anything apart.

Deal with the overheating issue first. Find out the exact CPU and GPU temperatures, whether they’re idle or under load, and what hardware is inside the prebuilt. Check that the fans are spinning, airflow isn’t blocked, the cooler is mounted properly, and the case isn’t unusually cramped. Around 80°C can be normal under load for some parts, but 90°C regularly is worth investigating. Prebuilt systems sometimes use compact cases or unusual layouts that make cooling less effective.
Start with beginner video tutorials, but watch several different people rather than relying on one guide. Pay attention to the comments and explanations, and use component manuals whenever you work on actual hardware. The labels on connectors, headers, and sockets are useful guides too. Practice on the spare PCs once you’re comfortable, and don’t force any part—most components only need gentle, even pressure.
That helps. I’m still worried about breaking something, but I’ll start with tutorials and the manuals before touching the spare machines.
When you’re ready to plan a new build, begin with your budget, intended games or applications, target resolution, and desired settings. Compare benchmarks, make a parts list, and check compatibility before buying anything. A compatibility-planning tool can help verify things like socket type, memory, power supply, case size, and cooler clearance. Manuals and a careful checklist are more useful than rushing—building a PC is generally straightforward when you take your time.
The CPU reaches about 80–90°C and the GPU is around 80°C during a lot of tasks. I’m going to identify the parts and check the airflow and cooler setup more carefully.
