The story here is incomplete. Some of these won't work until the BIOS is updated and for this model you see an Intel CPU with onboard video so you don't need the video card yet.
But did you just slap all the boards and parts in at one go?
That's not how to start off building PCs. You start with minimum parts to see what's what and then update firmware before the OS so you don't have to do that for a long time.
So, when i turn my pc on it keeps shutting down, then starting and again and again... The bad thing is that i have to get it ready for Friday because of a lan party.
My specs:
intel core i7-4790K (Not overclocked)
AMD R9 290X 8GB from Sapphire
2x 8GB HyperX fury ram
MSI Z97 Gaming 5
128 GB Plextor SSD
3 TB Seagate HDD
Corsair RM850 power suply
OS:
Windows 10
I need help quick!
