PC sudden gone very slow

Hi all,

I built this pc some years ago and its been flying along until yesterday. At first I noticed YouTube videos were acting funny and then the net felt a bit sluggish. So I put it down to everyone being at home and on the net at same time.

However, I noticed that when I went to watch a movie (not on the net) it was sluggish and was't displaying right.

Then this morning the pc shut down altogether by itself. So I opened it up and noticed there was A LOT of dust in there. Assuming this was the issue I removed as much dust as I could and the pc turned on after but it was very slow and sluggish and I'm just waiting for it to conk out again!

Any ideas? dust damage?

EDIT: It seems to have gone back to normal now. But thats after 5 mins on. I am sure it will go again.

If heatsink is clogged with "wool", you might be facing overheating issue and system throttled down to preserve itself.

UEFI might have utility's to monitor temps/fan speed, third party soft optional
Inspect/clean throughout you box. Take precautions if using vacuum cleaner(ESD)
