1 imp point: don't panic if pc doesn't starts right. most likely you missed to connect the cpu cooler power or the ram got loose or the video out cable was connected to mother boards port, not the GPU's.
Hah in my case the MCB tripped when I powered on my PC for the first time (circa 2008), I panicked so much that I didn't dare to power it on and called a system engineer; bloody right I spent a sleepless night and a scary morning. Turned out he just powered it on and it was working.

Heck this incident should probably go to the dumbest thread.
Panic. Never ever panic. Ever. Period.
I learned that it's best if professionals do it which is still a risk because most of today's professional's just call themselves engineer by doing some crash course in hardware and believe that all computer problems will vanish by a simple hdd format.
To be fair that does solve 99% Windows problems
