The laptop intermittently starts to slow down. What is the problem (Video card, hard, etc.)?

Question

Iron

The laptop was originally purchased in 2018, but the problem described below has been there since the purchase. The previous owner (I took it from my hands) did not apply to the service center under warranty, but simply put it aside a year and a half later on the shelf until I purchased it.

The essence of the problem: the laptop starts to slow down in games (this manifests itself in periodic slowdowns, but then everything goes away for about 5 minutes) and on the desktop (this manifests itself in cursor jerks at least).
I sin on 2 things: a hard drive or a video card.
I'm not sure how much the hard drive can affect the operation of the laptop, I need expert advice here.
I had doubts about the video card when I tried to launch the game pillars of eternity 2. It crashed immediately after launch with 2 video cards turned on. When I disabled (through the device manager) the integrated one, it started up, but lagged a lot (as with the periodic brakes that I mentioned above, but these were permanent).
When I turned off the discrete and left the integrated - everything went well.
It is unlikely that the matter is in the drivers. put them through HP Support Assistant on a clean win 10.

Specifications:
HP Notebook 15
Proc: intel core i5 8250U
RAM: 12gb
Video card: Nvidia GeForce MX 130

Answer 1

how hard drive can affect laptop performance

It can, and certainly does. HDDs are generally only suitable for file storage and are suitable, especially laptop ones. Even a simple SSD will give you a very noticeable increase in performance even by eye (provided that you can put an SSD in this laptop at all). Another thing is that this is unlikely to help with games, because neither the graphics built into the processor nor the MX130 will most likely take out even some kind of conditional dota at the minimum.

Answer 2

LOL WHAT?

When I disabled (through the device manager) the integrated one, it started up, but lagged a lot (as with the periodic brakes that I mentioned above, but these were permanent).
When I turned off the discrete and left the integrated - everything went well.

There are two types of graphon switching.
1 Manual in BIOS
2 nvidia optimus, switchable graphics amd (correct)
In this case, disabling the built-in is a very stupid idea. Because and then the discrete will fall off and the performance will be like that of a standard vga driver. They switch themselves.
And in general, any 3D process can be launched from the context menu of the mouse> run with gp> select the one you need. Testing
To begin with, I would do a clean install of nvidia. Firewood download from the website hp
Then tests in furmark. And keep stable fps. If unstable, then throttling.
Change / clean cooling and further test
