My Computer Suddenly Died

The Gateway computer we had in the shop suddenly died.
The screen froze suddenly and the cursor wouldn't move anymore.
The Enter key and Windows key stopped responding, so
I held down the power button to restart, and

then this screen appeared, followed by

this.

I held down the F2 key to enter the admin screen,
but the HDD isn't showing up.
I tried everything from there but couldn't fix it.

Looking at the back of the unit, it was designed
without any consideration for even battery or memory replacement.
I could keep trying, but even if I fixed it,
I'd only recover the data and wouldn't use it afterwards anyway,
so I need a new notebook computer right away.
I had taken backups, but
the recent data that I transferred from the digital camera as article images
to the computer was lost.
I can't write about how to install Campagnolo on an Alex Moulton,
or the story about how I fixed a Racing Zero auction item that was sold
knowing the right end spacer was missing—sacrificing my own parts to do so—
or the story about the wheel with carbon spokes from Hunt or similar,
from the wheel brand Elite (which is unrelated to Elite bottle cages).
Plus, the images I needed for an article about cable-actuated brake power efficiency are gone too.
The spoke length calculation formula is safe, but
the recent ones blew away.
I also had my own "Sonar Theory"-based
SONAR-style spoke length calculation formula,
but that wasn't backed up,
so it's all gone.
Recently I've been using it for calculating spoke lengths
for wheels assembled with hubs stripped from the rear wheel of a WH-RS300
and the front wheel of a WH-S500.

This is the lid of the new notebook computer I bought,
with the NEC LAVIE logo on it.

I bought a somewhat higher-end model,
though I'm bound to underutilize its performance,
so I might swap it with the notebook computer at home.
The screen is a bit small, but I got the largest one I could find
in the size range without a numeric keypad on the right side.
NEC has a slash (/) above the 7 key on the numeric keypad, but
with the Gateway and most other notebook computers,
the key above 7 is NumLock, and it seemed I'd press it without noticing—
so I'd intend to press 3 and accidentally trigger Page Down,
which happened constantly.
The amount of life time lost to the NumLock key
is incalculable when added up.
So, not for the first time, but
I chose a model without a numeric keypad.

In my previous post I'm assembling the Nomu Lab wheel number one,
and I chose it because I can remember its spoke length by heart
without having to calculate it
(because my recent calculation formula is only at home).
