Hello tom's hardware community,
i recently build a new pc ( 2 weeks ago) with the below specs
Motherboard: Asus prime b450m-a
Cpu: Ryzen 3 2200G
Ram: Patriot Viper 4 series 8gb 3000Mhz
Gpu: Gigabyte radeon rx 580 8gb
Psu: evga 500w w1
HDD:Western digital blue 3.5" 1TB
SSD: Kingston A400 120GB

I build up the pc and i was so excited cause it was my first time building a new pc on my own, everything went fine,the pc was going fast enough for me,i was playing every game totaly perfect in ultas settings and i was general totaly happy. Until one day my pc started making a strange noice for me while booting up, it was like a "tik-tak" like a whizzing from something (i think from HDD), then the next day made also another strange sound while i was clicking a game to open so i can play, a sound like whizzing again like something is scratching, and today that i am writing all this problems still going but the new one is that my pc started being really slow, i remember the first days i was clicking on a game and in a few seconds i was in the main manu ready to play and now it takes up to minute to open a game. i would like to have your opinions guys...do you think it may be the HDD?
BTW everything is new with guarantee
