Parts 1..8 are not caps, but coils. They should read as low resistance, like when touching both tips of your multimeter.

Is the fix for you or a customer ? If for you, and you do not find/want to spend in that board, could use a piece of other flat cable as a wedge to help secure the keyboard cable inside the connector. A little ghetto, but sometimes it is the way ....

The best way would be to dessolder the chip, read it with a programmer ( cheap Ch341a from china should suffice ). Then do the necessary changes to the file, flash it again to the chip, and solder it again to the board.
There are clips to access the chip while soldered in the mainboard, but they do not work always ( depend on the board and on experience of user ) . So, the easier way is to remove the chip.

Hello,
Test ram with Memtest x86, for example. Also check if it is overheating when it reboots.

Usb connectors are a pain to find. You need to look at AliExpress, and compare the pictures. Of a lot of sellers.

If you want to replace the board, some bios configuration will need to be done about booting preferences, time/date, etc. But a replacement for the socked could also be installed. The hard part is that you will need to search AliExpress "by eye", comparing your part with the photos there.

Hello.
You will need a lcd controller board. Open the display enclosure, or search for some reference about the model of display your computer uses. For its age, it should be an eDP one, but better be sure.
Then you need an adequate controller and cable for it. The controller will take care of powering the display. You cannot simply solder a HDMI connector, these displays do not work like that....
