Hi, I rearrange my computer and run into some issues that might be caused by broken hardware, if so I don't have a clue what hardware might be broken. Actually the issues started after I put in a TerraTec EWX24/96 and replaced a HDD by a SSD. However, I have several old but still good HDDs, 2 brand-new HDDs, old and brand-new cables and the brand-new SSD, so I tried different setups. I own two TerraTec EWX24/96, both already were used with the same mobo, at the same time, but since several month I used the PC with both TerraTec EWX24/96 built out. Later today I'll remove this TerraTec EWX24/96 and will build in the other, into the other PCI slot. JFTR jack does start when selecting the RME PCIe card and running Arch installed to the SSD doesn't cause issues. Something is fishy with the TerraTec EWX24/96 and/or something else. I also had issues with a brand-new external USB device and the brand-new internal HDD, so the power supply, as well as the mobo or anything else could be broken. OTOH one issue not necessarily must be related to another issue.
