So I just finished my first pc build today. It doesn't have a proper GPU yet (I'm waiting for the GTX 1070), so I'm currently using the integrated graphics on the i5 6600K.
On the very first power on, fans started spinning, leds lighted up, all seemed fine. The motherboard's (which is Asus Z170-A, by the way) red diagnostic leds turned on and then shut off, as I believe they are supposed to, except for the boot_device_led which stayed lit. My monitor didn't get a signal through DVI, so the system didn't seem to post. I shut it down and tried it a few times with the same results. After a few tries and after rearranging the cables so that nothing could possibly touch the motherboard, the system finally did post and I managed to get into the bios screen. Since then, the system has posted successfully every time, though sometimes the boot_device_led light has stayed on.
I also noticed in the bios screen that the RAM was at 2133MHz, even though it is 3000Mhz DDR4 memory. Maybe someone could elaborate this? Also, one time that the system failed to start again was when I set the XMP setting in bios to auto (it was on manual, though I hadn't touched it until then). After I saved & exit, the system once again failed to give a signal to the monitor.
So what possibly caused the problems in the first startups? I don't like the inconsistency, as I didn't really do anything that could've fixed it when it suddenly started working
. I'm worried it might fail to post again.
Could anyone help me?
