Just some ideas: I’ve used programs like Advanced System Care Free, Ccleaner and the like. Clean uninstalling and updating drivers some times helps. It is probably a registry problem so could take ages to find, if ever, while the above can save time. Tweaking.com’s Windows Repair can also help. Reflash BIOS? Generally if the above fails it is hardware but over 35 years or so I’ve rarely had hardware fauilts - well apart from old spinning hard drives. Let us all know how it goes.

Obviouly some one has completely re-formated the hard drive and wiped Toshiba’s Factory Restore partition. Just download and use the Mircosoft Product Key on the underside of the laptop or use , on the existing OS, one of the programs that finds the product key on the hard drive. Probably best to do both or find a used XP CD with a product key. Just curious. Why do you want to do this?

Do a “sector by sector” copy which is slow but makes a perfect duplicate. Acronis True Image backup has this setting in “Creation Mode” If I rememberr correctly.

When using the W7 install disk can you get into the command prompt and see the directory of the C: drive? If not it is probably corrupted. This does not mean it can not be repaired.

Yes. https://www.youtube.com/watch?v=bbq0pYq3... A SATA to USB external adapter will be necessary to copy the old drive to the new SSD using cloning software such as Acronis, EaseUS Todo Backup , Macrium Reflect , Clonezilla, etc.

I would try another power supply - have you a spare or can you borrow one to test?

Go into BIOS and make shure Wi-Fi is turned on. If this doesn’t fix it go into Control Panel, Device Manager, Network adapters and uninstall all of them. Shut down Windows/computer. Turn on and boot up. Let Windows discover the network adapters and re-install drivers. If none of this works you may need to replace the Wi-Fi card inside. Search iFixit for the Repair Guide.

Type “dell inspiron 5570 service manual” in Google and download the pdf. All is explained within.

From your video it IS loading the BIOS. How long do you wait?

Try this: Does it make any difference if you boot up with the TV connected rather than plugging in HDMI after boot-up? If that doesn’t fix it try uninstalling both graphics drivers and reinstall with latest drivers. Let me know how it goes.
