New PC gets slower and slower throughout the day

0

PC is less than 1.5 months old. Win10. I used to use Mac and tend to leave it on for days at a time, only putting it to sleep when I wasn't using it. It's impossible to do so with my new PC, and since last week the performance would slow down gradually throughout the day, the memory % in task manager climbing up steadily from about 20% at start up in the morning, till 60-70% at night. If I put it to sleep in the middle of the day (when I nap or leave the house) it would shoot up to 70% the moment I get it running again.

The main programs I that always have running at the same time are Chrome, Paint Tool Sai2, Discord, a video player / music player. I've kept an eye on the Task Manager for the last few days, with all those running at the same time it usually only gets up to 40-50% of memory usage. The main problem that I suspect is the seemingly countless 'Service Host's, those would pile up the memory % overtime, worse if I put the pc to sleep for a few hours and start it back up. The service host's runs at about 105-130+MB, and there are about 20 of them in the task manager. I've tried to increase the bandwith for them(?) with a method that I googled, and it lowered the usage a little (as I've written above, it could easily go over 80%)

What are these service hosts? Why are there so many of them and how to prevent them from piling up? Imma list my pc spec below if that helps. It's a custom PC, I've double checked with the store I got it from that it should have everything a regular pc should have + the custom aspects

AMD Ryzen 5 2600 Six-core processor 3.40 GHz 16GB RAM Motherboard ASUS A320M-K PRIME VGA Asrock RX560 4GB DDR5 SSD Team 256GB SATA III + Seagate 1TB PSU Enermax NAXN 500W 80+

I'm absolutely horrible with IT stuff, any help is very much appreciated, thank you!

Computers normally do not slow down with use. The specifications you posted are fine. Restart, use a minimum number of applications and only 2 or 3 Chrome tabs. Watch this. If if still slows down, scan for Viruses with Windows Defender (Full Scan) and see if there is a virus or other malware causing the issue. – John – 2020-02-23T14:04:40.930

@Moab, the 4GB reference is video memory (dedicated graphics adapter) while the machine has 16 GB RAM on board. – fred_dot_u – 2020-02-23T16:00:08.493

If the service host that slows you down is called "delivery optimization", then that's simply Windows updates in the background. – Natsu Kage – 2020-02-23T19:48:30.887
