Hey guys, long time lurker first time poster.
So, I've had my Predator Helios 300 PH315-51 (full specs below) for about a year. Everything was fine (more or less) until June-ish this year when it started to slow down. Not just with gaming, whenever I was doing anything the system would freeze for 1 second or so, whether I was browsing the internet, on a word document or watching a video, and then continue as normal. It would also make a short 'whirring' noise when this happened. This also meant games such as CSGO and Valorant would completely freeze for 1-2 seconds, with the audio still continuing.
So, I did a clean install on my SSD, reinstalled windows and it solved the problem until a couple of weeks ago and the same thing has happened again. While gaming, everything will be OK (although it's getting worse) at first but the longer I play (30 mins +) they will start freezing for a few seconds and the audio cuts out, although noticeably when there's some action happening. I also teach on zoom and as you can imagine this is a really annoying problem to have with everything randomly freezing for 1 second. It's also a really difficult problem to look up on Google, as I can't quite find solutions to my problem, only similar problems and the solutions haven't worked.
Here's what I've tried:
Using throttle stop to undervolt (followed a guide, worked perfectly in the past and the temp is at a cool 43 degrees idle)
Uninstalled specific windows updates
ran a /scannow (no problems)
checked hard drive for errors (none)
updated graphics drivers
set windows virtual memory to the recommended values
disabled enhanced sound effects (not ideal because it lowers the speakers' volume so much I can't hear anyone)
cleaned dust from the vents
scanned with malwarebytes and bitdefender (nothing found)
I know you guys get a lot of questions like this and it can be annoying to repeat yourselves, but I would really appreciate some help on this one. As I said, I haven't found anything regarding the same issue I'm having and I'm loathe to do another fresh install barely 4 months after the previous one. I'm considering reapplying the thermal paste, but this is happening doing basic tasks, even switching between apps so it's not an overheating issue.
