[SOLVED] Built a new PC, issues with RAM and boot drives

[fttfdl]

I built a new PC mostly from scratch today. The only parts I didn’t buy stand-alone were a pair of DDR4 2666Mhz sticks made by Micron and an i7-8700, both of which I took from a prebuilt I had.

Unfortunately, there seem to be some problems. For one, the only RAM slots that are working are the 3rd and 4th ones. I have tried both RAM sticks in all 4 slots and only those two seem to work. Whenever I try to put the second stick of RAM in, the DRAM debug light comes on solid for a few seconds then flashes for a split second to the CPU before going back to the DRAM light.

Second, something that’s very strange which I don’t understand is the motherboard tried to boot up from a hard drive which had no OS on it instead of my SSD. This caused a problem where Windows would try to “repair” the disk but just ended up giving me a “recovering” loop. This was “solved” by me disconnecting the HDDs and leaving only the SSD in. When only the SSD is in or I specify every time I boot up that the ADATA Drive is the boot drive, things seem fine aside from no Ethernet connection.

And third, my Ethernet cable isn’t being recognized. So I have no internet except Wi-Fi which isn’t exactly ideal.

I’m really hoping the motherboard isn’t fried somehow because that would really suck. It took me a long time to build this thing, I really hope I don’t have to send the motherboard back to Amazon then reconnect everything all over again 🙁

Please check the Motherboard Socket for Bent pins. You can send pics via third party websides like Imgur.
If the Socket seems to be fine just reseast the CPU.

BTW: What cooler do you use for your CPU?

The CPU itself works just fine, the only issue I’m having now is the fact that only two RAM slots seem to be working and it’s slot 3 and 4. I updated my drivers for LAN and now Ethernet seems to work. Still no dice with the RAM though.

Bent pin(s) in the right locations can cause memory issues like this even though the cpu seems to run. This is quite common and usually the pins on the outer edges. Heatsink overly tight can also cause memory problems.

Regarding your drives, check boot order in bios.

As for Lan, need to install network adapter driver from manufacturer's website if dont have an optical disc to use the driver cd the motherboard comes with. z390 is too new for Win10 to have drivers available natively.

Let me jump to the second question. You need to boot into your BIOS and change the Boot order so that your pc first would boot from the SSD. If you only have two working RAM slots, than you need to use the one works, probably with a higher RAM stick.
