Step one: Find a webpage or retailer that has decent prices, research is key.
Step two: Decide what you will use your rig for (gaming or work, or to sit on?)
Step three: Assemble a list of components, check basic compability (does the motherboard fit in the case, is the powersupply strong enough, does the motherboard support the other parts you want?)
Step four: Make additional edits to your component list according to reccomendations and tests online.
Step five: Order the parts. The basic stuff you should have;
A static electricity removing bracelet (easy to get in PC stores, static can with a low probability ruin your components)
A case
A powersupply
A motherboard
A processing unit (get cooling paste!)
A fan for the processing unit (often included)
Ramstick(s)
A harddrive (reccomend finding one with higher RPM count)
A graphics card
A DVD drive
The apropriate wiring usually comes with the packages.
Step six: Wait.
Step seven: Review the booklets you recieve with your PC parts, youtube is also a great source for PC building. I build mine like this:
Case first
Then screw in the powersupply
Then the motherboard
Then the HDD and DVD drive
Then the processor
Then ram and graphicscard
Then plug in all the wire, strap away where needed. Make sure the wires can reach where you decide to put the component.
Step 8: Try starting your pc, does it boot?
Step 9: Enjoy your pc or start looking for faults, the most common are:
- PSU not strong enough to boot
- Wires loose somewhere
- Dud components, often due to static electricity or bumps
Step 10: Review faults with a proffesional and replace parts if broken. If pc works, ignore step 10.
Step 11: ???
Step 12: Profit.
