How to Set Up a New PC the Right Way
Whether you just built or bought a new PC, it pays to optimize your setup from the start
Nothing holds more promise than a brand-new PC. The hardware is fresh and full of potential, the OS is clean and clutter-free, and you have nothing but pure, unadulterated storage space awaiting your precious data. It’s an exciting time, indeed. But before you start dumping old files onto your new rig willy-nilly, and downloading every shiny bauble of an app that catches your eye, take some time to consider a more measured approach to moving in. After all, you only have this opportunity once.
The way you set up your new PC now will have a lasting impact on your experience over time. Do it haphazardly, and your experience will be plagued by disorder and regret. Do it thoughtfully, though, by following the course of action we prescribe on the following pages, and you will have a machine that’s primed and ready to meet your every need from the start.

Check Your Specs
If you’ve just built your rig or unboxed a sparkling-new PC, it’s always a good idea to verify the hardware specs to make sure all parts are actually performing as they should be. We’ve seen simple BIOS misconfigurations downclock chips by hundreds of megahertz.

Inspect CPU-Z's memory tab to see if your RAM is configured correctly for double- or triple-channel, and that the frequency is set to the level you paid for.
First download CPU-Z. This excellent free utility will query your CPU and report the model number, cache size, and clock speed of the chip in real-time. To test your CPU’s speed, put a load on it using, say, Prime95 and run a stress test. CPU-Z should report the correct clock speed for your chip. While you’re here, pull up Task Manager by hitting Ctrl+Alt+Del. Select the Performance tab and make sure that each of your cores, virtual or real, is represented. Believe it or not, we’ve seen Hyper-Threading turned off occasionally on some systems.
Turn off Prime95, but keep CPU-Z open. Click the Memory tab. You should see the memory frequency reported under DRAM Frequency. This is the base clock, so you should double it to get the frequency of the RAM. For example, if your DDR3/1600 is reporting as 667, your RAM is actually running at DDR3/1333 speed.

TechPowerUp's GPU-Z will tell you what speed the PCIe is running at.
CPU-Z will also report graphics speed, but we prefer GPU-Z for more detailed info. GPU-Z will generate a CPU-Z-like interface. Pay particular attention to the default clock speed and memory speeds for your GPU. If you paid for an overclocked GPU, check that it is running at the speeds you paid for. GPU-Z will also tell you if SLI or CrossFireX is enabled or not and also at what speed the PCIe slot is running. Yes, it's possible that a new machine will have the GPU running in a slower slot, which may impact performance.
Stress It Out
If a component is going to fail, you want it to fail while it’s under warranty. For CPU stress tests, we prefer the free Prime95. Just download it and run the in-place stress test. A properly configured and cooled stock-clocked system should have no problem running Prime95 for hours on end. For GPU stress testing, FurMark is still quite popular, or you can run Unigine’s Heaven benchmark in a loop for a few hours. Keep in mind that stressing the GPU will also stress your PSU and cooling, so any shortcomings may crop up there, as well.
RTFM
Did you know your motherboard has a special USB port that allows you to make BIOS updates without a CPU being installed? No? Well it’s right there in the frakking manual. One of the first things you should do with your new machine is to read the documentation, particularly the motherboard manual, that came with it.
Store Your Extra Parts

Once you’re done building a new PC, collect the extra modular power cables, drive rails, special sound-dampening drive screws, and put them in one place. You could even store the extra parts in your case, as long as there’s room to spare and it won’t block airflow. You won’t thank us now, but you will in three years.
