Hi, I can help with the issue.

Computer technician: WesPCDr, Computer Enthusiast replied 2 years ago

With this type of issue, there could be several causes for this.

First, unplug the power cables from the back of the server.

Then, open the main chassis cover and re-seat the power supply cable, memory chips, and hard drive cables.

Also, look for any PCI cards that you can re-seat as well.

Look for any dust inside the server and clean with an air can to remove from the inside of the server.

Once everything has been re-seated, leave the cover open and plug the server power cable back in.

Power the server on and see if the CPU fan will spin and if the server works now.

If not, unplug the power, remove the memory from the server and then plug back in to see if you hear beeps.

Let me know how it goes.

Thanks

I have done everything but reset the drive cables and clean out dust. Will try. The server is my only AD. The other email address I have is***@******.***
Customer reply replied 2 years ago
Still no change.
Computer technician: WesPCDr, Computer Enthusiast replied 2 years ago

The problem is then with the hardware. The single ***** *****ght indicates a power problem or internal hardware problem.

This means that a new power supply or motherboard must be purchased to fix the problem.

Check to see if it's under warranty and you can get a replacement part.

Most likely, the motherboard will need to be replaced.
