It's impossible to tell from your first post what the issue is.  A system that takes multiple tries to startup probably has issues that go beyond just the SSD.

If it is the SSD you wish to upgrade anyway, you can't go wrong with a Samsung 980 or WD Black drive -- but there are plenty of other options from Crucial and others as well.

SSDs with heatsinks are designed for desktop systems and will not fit a notebook.  Any heatsink you might add needs to any SSD needs to be slim enough to fit into that system -- meaning you will be very restricted in choice, as there is not much space in the system for a heatsink.

Can you please give me the link of extremely fast nvme ssd without heatsink?

One of those is the M.2 WIFI card.  The system takes only one M.2 2230 (short) or M.2 2280 (long) SSD., so you would need to replace the M.2 2230 with the same, or replace with an M.2 2280.

I opened my laptop and it has 2 extremely small nvme ssds, with this work and will this fit for my laptop?
