WARNING: Before you start troubleshooting remember that you
are dealing with electricity that can KILL.

Only work inside the computer case when the power has been
switched off and disconnected. Never open the power source.
Some of the below steps
recommend removing physical parts within the computer.
While in the computer it is
highly recommend that you be aware of ESD and its potential hazards.
Remove the memory modules from their slots.
Take the opportunity to clean the
slots on the motherboards and the memory module connectors.
Use compressed air to blow dust away and clean contacts with
a soft cloth.
Do not use a metallic vacuum cleaner if it touches any
component it may create a short and cause damage to the motherboard or other
components.
Do not use solvent that may attract
dust and never poke things like cotton buds in to slots. lightly
rub an alcohol (Methylated Spirits) on a cloth not to hard let the alcohol do
the work on the copper gold or silver tabs and r
Allow the pins to dry.
They will air dry in a matter of minutes
If reseating the memory did not
resolve the issue try swapping the location of the memory.
If you have only one stick of
memory in the computer try moving it to another slot and then boot the
computer.
Check the memory module and memory slot contacts.
They are either copper tin or gold.
The colour will tell you which they are.
Mixing tin and gold can result in corrosion that prevents
proper contact.
Look for any sign of physical damage to the memory module,
memory slots or the motherboard.
Reseat the memory modules.
You should hear an audible click when they are in place.
Do not use too much force to reseat the memory module in to
the slot this can cause damage to the module, slot or motherboard.
The hardware that you are trying to access is damaged or
failing.Could be a problem with the Hard Drive or the Hard drives

There is a connection problem such as a bad cable
Test all power and data leads that attach to your hard drive SATA
the leads from your MOTHERBOARD TO THE
HARD DRIVE make sure they have a
secure dust free connections and are not faulty.
Although it would be very rare for the sata lead to be
faulty.
Make sure all leads that are attached to your drives
dvd\cd have secure connections and are not faulty
Computers need power and data to travel through
every working device and continue its cycle and have an end so any faulty leads
will end up with a computer erroralso
Your laptop's cooling system consists of a cooling fan and a
heat sink, which is a metal plate with a copper pipe extending out of it.
When your cooling fan goes bad, it causes your CPU, or
processor, to overheat, which can cause irreparable damage to your laptop's
motherboard.
In most cases, your cooling system can be prepared by simply
cleaning out the cooling fan assembly. It's for this reason that regular
cleaning and maintenance of your cooling system is instrumental to the life of
your laptop.
Turn off your laptop and disconnect the power cable.
Disconnect any other cables or external devices and close
the LCD panel until it latches shut. Place the laptop face-down and remove the
battery pack from its compartment.
Place the laptop face-up, then open the LCD panel.
Pry up the keyboard bezel from the laptop with a flat-head
screwdriver.
The keyboard bezel sits between the keyboard and the LCD
assembly.
Remove the bezel and set it aside.
Remove the Phillips-head screws securing the keyboard to
the laptop base.
These screws are usually located beneath the keyboard bezel.
Some laptop models secure the keyboard to the laptop casing
from the bottom.
Those screws are usually located either inside the battery
compartment or on either side of the RAM module compartment.
Additionally, some laptop keyboards are secured by retaining
tabs located behind the top row of keys on the keyboard.
Lift the keyboard out of its compartment and place it
face-down over the palm rest.
Use a small flat-head screwdriver to disengage the black
tabs on either side of the keyboard ribbon cable where it connects to the
motherboard.
Disconnect the ribbon cable from the motherboard, and then
remove the keyboard from the laptop.
Remove the Phillips-head screws from the motherboard/CPU
cover or EMI shield.
The EMI shield is metal plate covering that protects the
motherboard and CPU assembly.
Remove the EMI shield from the laptop and set it aside.
Some laptop models do not have an EMI shield.
Remove the Phillips-head screws securing the cooling fan
to the motherboard.
Disconnect the fan cable from the motherboard and lift it
out of the laptop assembly.
Wipe dust off of the cooling fan assemblies exterior with
a soft cloth or paper towel.
Blow the dust out of the fan with a can of compressed gas
duster.
Use a small paint brush to remove the dust from deep inside
the cooling fan.
Work under good lighting so you can visibly see the interior
of the fan.
Repeat steps one through six in reverse order to
re-assemble the laptop.

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.
Hey readersFollow these steps to troubleshoot that issue.
Warning -Please don't your that tip for illegal work . Its only for personal and training purpose.
You can also follow my tip
It might be a connector cable between the mother board and the power supply has worked loose when the machine was moved. That blinking light appears to be on the power supply.
While there might be other causes, I suspect the power supply needs to be replaced.
You could take up considerable time and try to reseat everything and check all the connections and even put new thermal paste between the CPU and heatsink, but in the end, I suspect putting in a new (or used of the same type) power supply will be the fix. If the power supply has failed before damaging anything, that at least would be good news.
2006 PC (HP.coM) 16 years old.. ouch.
XP (microsoft) is now a horrible virus magnet, and there is ZERO support now, are you using the last XP earth 2020???

I bet there are 1millons of web site still with XP usage .(old topics)
google them. but Microsoft purged theirs.
it is not sold at all, so how in the world can you get the installer on any pen drive, and XP installed from CD not pen..
worst of all XP installer, can not us 99% of all USB ports and then only half after the install (unless you force them via F6 and floppy drive with xp drivers on the floppy for THIS PC)
to use any relic PCs run LINUX> not XP
Question edited for clarity, and Maker name.
Question moved from BBC Computers.
BBC Weather and Quora and both secure and have an http*S* security certificate. My guess is that you have a third party security app, or worse, two of them, not understanding status or fighting with each other.
