Hello together!
I have a very mysterious issue... my PC:

- GA-Z97x-UD3H motherboard
- i5-4690
- 8GB HyperX CL9 PC1600
- SSD + HDD
- AMD GPU + small Nvidia GPU

Now, until a few weeks ago everything worked fine.
But now I'm struggling with booting my PC. If I simply turn it on, it doesn't even beep and show the BIOS.
I tried almost everything like removing 1 or 2 of the GPUs or the mass storages, resetting the CMOS etc...


Finally, I found out that I can boot exactly then, when I before plugged off one or more RAMs and plugged it in another slot than it was before. If I do this, I can enter the BIOS and even boot normally. However, after the next restart, again nothing works. I have tried this many times and it behaved in 100% of the cases like this:

- moving RAM and turning on => everything fine
- doing nothing and turning on => not even BIOS

Independently of how much GPUs and HDDs are installed.


I can't exactly say, what has changed. But I installed the second GPU a few weeks before the problem began. Alltogether, the PC is ~1.5 years old.


Does anybody know what this could come from? Is my board broken?
Would be great, if somebody could help me!

All right, the problem maybe from the MB ( the memory slot).
You need to update the chipset driver from either intel or gigabyte site, or even the BIOS to make sure there is not the software problem, the chipset driver comes with memory controller driver. If you done those and you still have the same problem, either return the MB or use the RAM in other slot so that the PC can boot.

Hey, thanks for your answer!

I should have wirtten, that I have 2x 4GB RAM. And no matter, which RAM is removed, the problem is always the same.
Only exactly if at least one of them has been moved to another slot, then the system boots.

I think, it's not a RAM problem then?
