Wow, this build I'm doing at the moment has been a bit of an adventure. I recieved all of the parts, assembled it, and got ready for a test run... which ended up with the computer starting for 1.5 seconds (no POST at all) and then shutting down, automatically repeating the process over and over until unplugged or the PSU was turned off. After checking all installations and wires, I determined nothing was wrong hardware-wise. After a bit of research, though, my brother and I figured out the issue. And it turned out to be rather annoying.
I bought the GIGABYTE Z87M-D3H and the Intel i5 4460, a motherboard and CPU which are 100% compatible. No issues, I thought. Except for the fact that the mobo shipped with an outdated BIOS, a BIOS that just so happens to not support Haswell Refreshed CPUs/Z97 chipsets. Unfortunately, my i5 is just that. So, in order to update the BIOS, I need a pre-refresh CPU to drop in temporarily to flash the BIOS. I went to Micro Center to see if they could do this for me, but they didn't have any Z87 CPUs they could use to do it with. So, I've now broken down and bought a SECOND CPU (Celeron G1820) to temporarily drop in to update my BIOS. That's $45 for 5 minutes of use, just to flash a BIOS.
