S5000psl "No Video"

If you get three beeps with no memory, your processor and BMC are fine.  Maybe the memory got damaged somehow, when you were moving the jumpers?

Have you tried clearing the CMOS a second time?

Hello,

Firstly, please download these files as reference:

Technical Specification from the Website

BIOS & Firmware Pacakge:
from the download Website:

How to create a bootable USB stick:
http://gocoding.com/page.php?al=bootflashdos

Now from the Technical Doc:
Page 45 out of 75 explains to you how to make a cmos clear.
Put back the jumper when done.

Once this is done, make a fat-formatted bootable USB using the Tools from the website above.
Download and extract all the firmware package from the above links. (note: extract the zip files.)

Now again from the Technical Doc:
Page 45 out of 75 explains to you how to switch the jumper to the secondary bios.

So, switch the jumper to the lower bank bios, and then boot the system.
Press F2 to go into the bios.
Go to Boot Manager.
Boot onto the bootable USB stick.
Flash the bios by running BIOSxx.BAT batch file.
Once this is completed, flash the bios again one more time reason being that there is two bios banks.
Power off the system when finished.
Put back the jumper.

Power on the system.
Press F2 to go into the bios.
Go to Boot Manager.
Boot onto the bootable USB stick.
Update the firmware of the board by running:
BIOS96.BAT for the bios
BMC64.BAT for the BMC
FSP42.BAT for the SDR
Restart the system and check if the firmware have been flashed correctly.
Bios Version: xx
Go into Server Management >> System Information
BMC Version: xx
SDR Version: xx

Hope this helps you a bit where to start. Let me know it goes.

Kind Regards,
Aryan.
