Toshiba Satellite C670-15W upgrade?

My friend always complains about her very slow laptop, which is understandable because the hardware is extremely out of date.

However, since she only surfs the Internet and occasionally does homework on this PC, she does not need a new one.

I therefore wanted to replace some parts and have a few questions about it.

Hard disk:

The Toshiba MK7575GSX with 750 GB is installed

I would like to convert this to an external one and install an SSD for the operating system instead. Does a normal SSD hard drive fit in instead of the MK7575GSX? (e.g. Samsung Evo, not these small M2 that come in newer laptops or mainboards) If not, how can I replace the HDD with an SSD? And does the toshiba c670 possibly have an M2 slot for SSDs?

R.A.M:

A 4 GB DDR3 Ram is currently installed, which I would like to expand to 8 GB.

It has 2 slots and has a maximum memory of 8 GB Ram as far as I have read it.

However, the homepage of the laptop says that I need PC3-12800 (DDR3 1600MHz), but in CPUID it says that only 665.1 MHz are used as DRam Fraquency. So which ram is now installed? A 1600MHz or lower?

And what do I have to watch out for, which RAM bar fits as a second RAM bar so that I have 8 GB of RAM? (Image of CPUID is attached)

Processor and graphics card:

An i5 2430M is currently installed as a processor and an Nvidia 520M as a graphics card.

Are these upgradeable? If so, which processor should I use that fits on this socket? (Socket 988B rPGA) and which as a graphics card.

I think these components are enough for their purposes, but I would like to know.

I would have a solution that doesn't cost money:

Simply install the Linux Mint operating system on it. I recommend the xfce edition. This only requires a fraction of the system resources that Windows normally requires. Even with this equipment it runs extremely fast. As with Windows, the desktop also has a start menu and a task bar.

Here is the download: http://mirrors.evowise.com/linuxmint/stable/19.3/linuxmint-19.3-xfce-64bit.iso Then write the ISO with Rufus https://rufus.ie/ on an empty formatted USB stick.

When that's done, just boot the stick and follow the wizard's instructions. It offers the possibility to delete everything. I recommend a full installation. Firefox, LibreOffice and multimedia components are also installed. During the installation, the hardware is recognized and automatically set up. The WLAN is also recognized. Have the WLAN key ready.

After completing the installation and starting Linux Mint for the first time, the update manager will appear in the task bar next to the clock. You should install these updates right away. The update manager not only takes care of the system, but also of the installed programs. If new versions appear, he reports it and offers an update. You no longer have to update every single program as with Windows.

The flash player should only be installed if you absolutely need it. To do this, start the terminal and enter the following command:

sudo apt install flashplugin-installer -y or sudo apt install adobe-flashplugin -y

This installs a script that automatically downloads and installs the latest flash player from the Adobe site.

Windows fonts such as Arial, Times New Roman etc. Are also available for Linux. To install it, simply enter the following command in the terminal:

sudo apt install ttf-mscorefonts-installer -y

This is what the desktop looks like:

If you e.g. If an external hard drive or USB stick is plugged in, a dialog box appears and you can then access it.

I also have a 10 year old laptop with a first generation i3 and 4GB RAM. I also installed Linux Mint xfce on it. It also runs extremely fast.

Thank you for the answer and all the work, but I had Linux on it beforehand and my girlfriend was very dissatisfied because she mostly uses this laptop alone and has absolutely no idea about something like that. I had to help her with something almost every day. You want Windows, so I'm looking for the hardware upgrades, I think expanding the ram and installing an ssd won't cost that much, because you can easily get away for under 50 euro if you continue to use the HDD as an external card and only Windows on the SSD Installed
