Hi. Trying to sort my sisters Samsung R40 plus, laptop out

Very very rarely boots to windows.
Tried getting into bios BUT as soon as I get into the bios screen (F2) and press any buttons, that's it. No more key presses registered

Striped laptop down. Cleaned all dust etc out with air compressor.
Removed CPU fan assembly, cleaned with IPA and re-applied artic silver.

Re-assembled laptop. All starts, fan makes a 'grinding' type noise. ( did that before I started looking at laptop)

But again. Won't boot to windows or allow any further key presses when in bios after first key press

Any ideas?

Thank you
