One long beep usually means a memory or RAM error..
Try removing the ram sticks and then simply replacing them back into the slots..
The contacts in the RAM slots are self cleaning to taking the sticks out and putting them straight back is usually enough to correct this issue..
Just make sure you touch part of the metal chassis of the tower BEFORE you touch anything else.
This will discharge any static charge you may have on your body..
To check whether a Power Supply Unit is Ok or dead, simply take a cut-out wire and do a jumper as shown below:
From Green to Black (there two female connectors in between them). Now power on the Mains (outlet) switch. If it's working or if it's ok.. smps should power on.
Unfortunately, if the manufacturer states that the max RAM supported is 1GB, that's going to be all you're going to be able to install - unless you replace the motherboard. This can be a considerable expense.
One last thing you could do is go to Crucial - there, you can run a scan on your computer to find out what memory options you have. I would be very surprised to learn they differ from what Compaq is telling you (unless the motherboard was replaced by someone already).
The above link is provided to give a closeup side view, of a DDR Sdram ram memory module, and it's gold plated contact pins.
Use the pencil eraser to stroke down each contact pin. Both sides. (A DDR Sdram ram memory module has 184 contact pins. 92 on each side)
Refrain from touching the contact pins with your fingers. You can touch the body of the module anywhere you wish, as it is coated with a see-through protective plastic.
If an eraser on the end of a pencil is used, do Not let the metal part of the pencil, rub against the contact pin.
Use air to remove the eraser dust. You can use a can of compressed air for computers, or air from your mouth may be sufficient.
Reinstall the ram memory module/s.
HP Support product specifications, indicate the Compaq Presario S5100NX comes with one - 256MB DDR Sdram ram memory module.
If there has been two ram memory modules installed, suggestion is to reinstall one at a time, to see if there is a bad ram memory module.
Yes, it's kind of a pain.
When installing just one ram memory module, it is installed in Slot 1. The ram memory slot that is closest to the Processor.
Scroll down the above page until you come to the motherboard illustration, and the motherboard photo underneath it.
In the motherboard illustration - DDR DIMM 1 (64/72 bit, 184-pin module) indicates Slot 1.
Install one cleaned ram memory module in Slot 1, plug the computer into power, WAIT 1 minute, turn the computer on.
Works?
Computer shut down normally (Start>Turn Off Computer>Turn Off), unplug from power, observe anti-Static precautions.
Remove that ram memory module, install the other one.
[Anti-Static Precautions:
Your body carries Static electricity. Static WILL fry out (Short Circuit), the hardware components inside a computer.
You may not even see it, or feel it. (Hmmm, I did everything right, but my computer doesn't work)
Computer on a table, unplugged from power, computer case open. TOUCH the metal frame of the open computer case, to relieve your body of Static.
If you get up, and walk away in the middle of working on your computer, upon your return Touch the metal frame again ]
Note the Locating Notch, on the bottom of the ram memory module. It lines up with a Locating Lug, in the bottom of the ram slot on the motherboard.
At a casual glance the Locating Notch may seem to be in the middle. It is Not. Assure that you have the module turned the correct way when reinstalling, so that the Notch lines up with the Lug.
Note the Locks at each end of the ram slot. (White in color) The top of the Lock is eased towards the outside. (Away from the ram slot) Ease both Locks up at the same time.
Note that the bottom corners of the ram module, sit in small slots, of each Lock.
As the ram module is pushed down into place, the Locks are brought up simultaneously.
Note that there is a Notch, on each side of the ram module. The Lock has a protrusion ('Bump') that fits into the Notch, when the ram is fully seated in the ram slot.
Sometimes the 'Bump' does not fit in perfectly into the Notch. It's okay.
If there are two clicks, from the Locks snapping into the Notches, the ram memory module should be fully seated.
Basic video guide, to installing ram memory in a desktop computer,
Click Start, Settings, Control Panel, then double click the "Sounds and Audio Devices" icon. Make sure the Mute box isn't checked and the Volume bar is at least 1/2 way on the Volume tab. Also click the Speaker Volume tab and adjust the sound there as well if needed. You might also want to check the "Place volume icon in the taskbar" icon so you can easily adjust the sound settings next time.
Is there more than one fan inside the computer? Did you double-check the connection from the fan to the motherboard? Sometimes a computer will shut down if it doesn't sense that the fan is turning on, to prevent the computer from overheating.
Along with the PC comes a restore CD,start the PC with this disc and follow the instructions to complete the setup with the help of the Original OS CD. Put in the keys and activate it over the net or microsoft toll free telephone no........sodeep
Is the Driver sor the sound card up to date, try to see if it is even installed, if it says that no audio device is installed, go to the drivers page for your computer, and then download the sound driver for your sound card
Is is probably too old to take Win 10. Also, USB support normally starts once Windows is loaded. During Boot up, it looking for a hard drive or Bootable CD Media.
By default, the notebook can start only from a bootable hard drive
or bootable drive medium in the notebook.

It is 21 years old!!
Windows 7 should be the OS.
If you go to safe mode, it should complete booting and then you can list the errors but I suspect there is a driver error. Maybe the wrong version in there.
Hopefully it will still work with a new battery and power supply to charge it.
They were quite reasonable back in 2008. Win7 software (no longer supported) and fairly fast.
