I follow this basic outline when building a system, and everything is done at stock clock speed. I don't do any overclocking until the system is first stable in a basic, stock configuration.

1) Assemble everything. Start out right with your cabling tidied up in the case. Be particularly careful with correct thermal compound application and heatsink installation.
2) Update your BIOS to the latest version.
3) Reset your BIOS to factory defaults. Yes, the updater should do this, bit do it manually just to be sure.
4) Install your operating system.
5) Download all the latest drivers for your system from the manufacturer and install in this order, rebooting as necessary:
6) Let your operating system run its own updates. (Might take a while...) Reboot when it's done, even if it auto-rebooted, do it one more time.

Now start testing your system for functionality and basic stability. Find and resolve any problems now, so you have a good foundation to start with. Install a few applications that you're famaililar with, and make sure they run as expected. Don't bother customizing any setups until you know the bare-bones configuration is stable.

Now, you can begin tweaking.

First, turn on the XMP profile for your memory in the BIOS. Then run your system and make sure it's stable and working as expected under just the basic XMP profile. This is the basic performance level including the necessary settings to work with your memory's rated timings.

Notice I haven't recommended installing any of the extra software that come with your board yet. No GUI overclocking software, no GUI extras, no RGB lighting control software, no gaming extras. Just bare-bones stock plus XMP, all done on the BIOS. If your system runs and proves itself stable this way, then you can decide first what extra software to add. I recommend keeping it simple; if you don't expect to use it - don't install it.

Does your system check out? Running smoothly? Great! Now you can consider tweaking and overclocking. But that's a whole other process and learning curve. If you intend to go deeper, don't bother installing any more games and applications. Because if anything goes wrong while doing advanced tweaking that messes up your OS installation (Like a hard crash that well and truly corrupts Windows' boot records -- It can happen!) you won't have lost the time only to install it all over again.

System building is fun -- just take it slow and carefully, and be methodical. That's how to avoid frustration.
