Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi Guys,

I´m not able to get my new PC run.

ASROCK X570 Steel Legend
AMD Ryzen 3900X
G.Skill 32GB Trident Z Neo DDR4-3600MHz
Corsair MP600 PCIe 4.0 NVME SSD

AMD 5700 XT (was already runningin my old machine)

When I start the computer I get no screen / post. on the PSC (Post screen checker) only the Boot LED is lightning. At startup CPU und DRAM are lightning for some seconds than it goes back to BOOT LED only.

What does the Boot LED mean? I´ve tried it with and without the PCIE NVME.

There is no further information about the PSC in the manual.

I also tried a differernt RAM and 3 different GPUs in summary.

Hope anyone can help me.

Thanks
