Why does the laptop slow down?

Question

Iron

I have a Sony Vaio laptop. Pretty old (more than 5 years - I don’t remember exactly). For the last 2 years, he lay dead - something broke and he did not turn on. Was not needed. Now needed again. I took it to the repair, where something was changed to 3k wooden ones and it worked. But the problem is that he just terribly slowed down. I couldn't even reset the system. When I tried to play a video on YouTube, everything barely twitched ... And the problem is not with the Internet. In the workshop they told me - change the hard drive to an SSD. Okay, changed. The situation has become a little better, but he still slows down. I also ordered a DDR4 RAM at the same time, it has not yet arrived. The problem is that again, I turn on YouTube and see that my processor is 90+ percent loaded. With one YouTube tab in the browser. What kind of bullshit is this? Previously, he worked well, although he did not fly much.

Processor AMD E2 1800 APU with Radeon TM HD Graphics 1696 MHz. Do I really have to change it too? (So I will soon change everything that is in the laptop ... I don’t have money to buy a new laptop now.

Answer 1

AMD E2 1800

Bury.
Only a new laptop will help, now probably in hours processors are faster than your laptop. By the way, it does not support DDR4, so the ordered memory will not be useful to you. And you can’t change the processor in a laptop with a 99.99% probability, so just buy a new laptop.
It’s hard to say about “worked before”, because E2, in principle, cannot but slow down. But in general, the trees were taller, the grass was greener, and the sites on the Internet were simpler, so it's possible.

Answer 2

I also ordered a DDR4 RAM at the same time, it has not yet arrived.

What a great guy, judging by this :
Supported memory: DDR3-1333, DDR3L-1066

When I tried to play a video on YouTube, everything barely twitched ...

you have a percentage of 2012, before the video stream was mainly transmitted as h.264, now by default it is usually hevc (h.265), vp9, av1 the
last two if you have not updated the percentage / video for the last few years will be processed programmatically and not " in hardware ", and this is a significant increase in the load on the percentage, especially for av1, if the percentage is weak, then the brakes are natural. It is solved by a browser plug-in or by setting the view through the player (for example, mpv + yotube-dl) that allow you to request a video stream in h.264 (the iron support of which is probably also in the iron)
p.s.
to slightly reduce the load on the percent from flickering any advertising crap in the browser, install ublock origin
ps2
if there is not enough money, then instead of a laptopbuild yourself a better stationary, it will come out much cheaper in terms of price / performance, even for example a regular amd 3000g + the cheapest motherboard for it on AM4 + 2 * 8 gb DDR4 will be enough for your eyes for the next 5 years

Answer 3

Over the years, browsers and sites are becoming more and more voracious. You have a weak processor, and you show him a modern YouTube. Try the lighter Pale Moon
PS browser and DDR4 RAM on an eight-year-old laptop, you powerfully came up with it

Answer 4

Processor AMD E2 1800 APU

With this processor, nothing will help the laptop become faster. And yes, indeed - how are you going to change the DDR3 RAM to DDR4?
