Dell PowerEdge 2850 - 2 beeps and no VGA output

Hi there,

I got a Dell PowerEdge 2850 from my company that was decommissioned. I tried to start it at home, but there is no VGA output and only 2 beeps.

Unfortunately there is no information about only 2 beeps in the manuals.

I made 2 videos of the issue:

I removed all parts and put them back again (including CMOS battery) according to: (Please visit the site to view this video)

But there is still the same issue.

Do you have any other ideas of what I could do or what the two beeps could mean?

Thanks,
