Got my first pc built, and it s up and running. It would've been a flawless build except for my putting the little led, power switch, etc cords in backwards, and it didn't turn on at first so I thought it was the CPU, do I had to take the heatsink off and everything but it was on right. Turns out my power supply cord wasn't all the way into the box.. Oh well. Any just have programs. I downloaded MSI after burner and another one that automatically detects drivers. Should I be adjusting anything - overclocking or any of that stuff?
Depends on your hardware and what you plan to do. Some people can't wait to start tweaking their GPU, CPU, and/or RAM while others are just content with stock settings (some people even overclock their monitors). Depending on your hardware, overclocking may not even be worth it. If you have an Intel K-series chip then there tends to be quite a lot of headroom whereas if you have something like an R5 1600x there's hardly any overclocking headroom at all, even with liquid cooling.
