PC randomly freezes for seconds

[hzxzhang]

I built a new PC few days ago and it will freeze randomly for a few seconds before coming back to normal. It does NOT freeze when I'm playing games, but when I am using discord, browsing webs and some other non-gaming stuff the freeze will happen. not sure where to find clues. plz help.

OK so i found where the problem is after replacing the motherboard and accidentally booted into windows through HDD. Yes I installed windows in my HDD before I got the tools to install SSD onto my motherboard. But I knew the speed of SSD so I installed windows on that again after SSD was installed. But there must be some issue with this copy of windows because when using the windows installed on HDD everything is perfectly fine. When it comes to the SSD, problem still exits. This explains both the freezing and the network timeout error. next step is get another SSD for me.
