Long-form guides on choosing, combining and troubleshooting PC hardware — written for the Tunisian market, where import batches and exchange-rate pricing make component decisions work differently than they do elsewhere.
Each guide is written to be read on its own. If you are starting from nothing, the budget building guide is the place to begin; if you have a parts list and want to confirm it works, start with the compatibility checklist. And if you are still deciding whether to build at all, the same reasoning applies to buying ready-made — price a build here, then compare it against the laptops and prebuilt desktops in Systems.
Fans spin but nothing appears on screen, or nothing happens at all. A methodical process that isolates the cause without buying replacement parts — starting with the causes that are free to fix.
Why the sequential speeds printed on the box have almost nothing to do with how fast a drive feels, what DRAM cache and SLC caching actually do, and how to plan storage for a build without overpaying for numbers you will never notice.
Resolution and refresh rate should drive the decision, not the model number. How to read the specifications that matter, why VRAM has become the limiting factor on mid-range cards, and what upscaling changes about the calculation.
Ten checks that catch essentially every way a parts list can fail to become a working computer — from the socket match everyone knows about to the clearance measurements that appear in no product photograph.
Both approaches move heat into the same air inside your case. What differs is where they move it from, what they cost, how they fail, and which physical constraints they impose — including one that matters a great deal in the Tunisian climate.
What actually changed between the two memory generations, why higher bandwidth arrives alongside higher latency, when the difference is measurable, and why the decision is usually made by your motherboard rather than by you.
Every build is bottlenecked by something — the question is only where, and whether it is in the right place. How resolution shifts the balance, why "bottleneck calculators" mislead, and how to identify your own limiting component.
Why adding up component TDPs gives the wrong answer, what 80 Plus certification does and does not tell you, how transient spikes trip adequately-rated supplies, and how to size a unit properly.
Where the money actually goes in a Tunisian PC build, which components deserve your budget, and the local market realities — import batches, exchange-rate pricing and stock volatility — that make advice written for other markets misleading here.
The PC Builder applies the compatibility rules discussed in these guides automatically, calculates the power supply wattage your parts list needs, and shows every tracked retailer price side by side.
