Need advice if I should thread on or ask for help

[Kyoren]

I have a Lenovo Ideapad z580. Which is a complicated piece of hardware for me to disassemble I bought thermal paste recently to prevent the video chip from downclocking due to heat from gaming sessions (GeForce GT 630m 1GB) and I saw a video where I have to remove the ENTIRE motherboard to be able to access the chips. I was already in the part of removing my disk drive, but when I saw the other things I had to remove, I stopped. I can disassemble it, yes. But I don't know how I can reassemble it if I do so. So should I continue with this or ask for help from a Lenovo Technician? (Which, there is one just a few miles away from me).

Also, the stock thermal paste has been in this laptop for about 3 years now. (From 2012) and I'm only aiming for the video card.. so should I also replace the processor one as well while I'm at it? and which technique of applying it should I use?

Here's my take on that... I will suggest doing it yourself, while it will probably feel very intimidating at first (that's natural, it's a foreign environment), there are some excellent (IMO) guides out there to help. After the second time inside, you'll likely feel like a pro. Really, it is that easy once you figure it it's just a lot of parts in a small area
Start with the Lenovo Z580 Maintenance Manual
Watch a video https/www.youtube.com/watch?v=F1oXKrlxTJc or a few (some are better than others)
Ask here for any clarifications.
One thing I will say, do not force anything - always assume you have missed something (a screw, cable or clip) and take your time. Some parts are stubborn but none should require force to remove/replace
The heatsink assembly is one piece for both graphics and CPU so you will need to do both - clean the vent out good too
I think it'll make for a good learning experience here but you're the one that'll make the call

Thank you so much! I recently had the courage to replace the thermal paste and now it's done after an hour!

Took a while, and yes, the scariest part was removing the tiny clips and sockets. But I managed to put it all back in one piece again.

CSGO FPS usually dips to 40 in under 30 minutes. But now it retains 70-100 FPS~ Thanks so much for the help :3 Should have believed in myself in the first place xDD good experience, nonetheless.
