"PST0256 - POST fatal error detected." Please help me with this issue.

Hello thanks for choosing Dell.

1. This happened after a reboot?
2. Is there any devices you added recently?
3. What we can try now is the "minimum to post"
 The minimum components to allow the Dell PowerEdgeR730/R730xd to complete POST are as follows:
 • System board
• One power supply unit
 • One processor (CPU) in socket CPU1
 • One memory module (DIMM) installed in socket A1
 • Left control panel (for power button functionality)
 • One backplane card

Hope this helps and have a great one!

Hello, DELL-Young E

I have another question

Will this error cause any major problems using the server?

Could you please tell me if it has something to do with server disk crash or CPU stuck/not working?
