Inexpensive motherboards are a terrible idea, they can cause really weird problems that look like issues with other components. I've built a few computers and since sworn never to buy a cheap motherboard again.
3 years ago, I purchased an Asus Republic of Gamers motherboard for 400 dollars. It was the most expensive component in my PC, and I hate it every minute of every day.
All my work is in bootloaders, but this motherboard has a terribly, terribly buggy BIOS. Restarting the PC is not a fun thing to do with this 400 dollar PoS.
Of course, the only reason BIOS upgrades failed to address this is because only a few thousand were ever sold... and mostly to gamers and not hard-core computer engineers.
