Hi,

this evening, all of a sudden my computer stops working. After switching it on again, both LEDs "DRAM" and "CPU" are red.

I've already tried all combinations of my two DDR4 bars, but nothing helps.

Does the LEDs mean that my CPU and the RAM got damaged at the same time? Does anyone have any ideas? Thank you.

Short answer: a CMOS reset has helped ...
