pc stuttering

[Elyie]

Long story short i bought a pc from here and it came maybe about a week ago and the rtx 2080 the noise coming from it i can only describe as a dog whining whenever i open a game, the fans seem to just start and stop nonstop 24/7 unless i force them to start with msi afterburner
and every game i've tried to play is stuttering like and has mouse (the mouse even freezes sometimes just randomly without even playing a game) and keyboard input delay the lot, i've tried switching to different mouses i have (steelseries, razer,logitech) and an old keyboard i've even lowered the settings in games to the lowest possible even messed around with g sync and v sync and the nvidia 3d settings on my 240hz acer predator monitor even tried it just on my other asus 144hz monitor, switched the ram out to some old corsair 3200mhz 2x8 sticks i have even tried downclocking the cpu mhz to default 3.6. also tried reinstalling most drivers
apart from downclocking the cpu to 3.6mhz from what it was set at by overclockers 4.8 and turning off and on the ram xmp profile i haven't touched anything else in the bios i don't dare mess around with anything i'm not too sure about
i'm kinda out of ideas on what i should do
if i should send it back or what

The first thing I'd do is ring the shop or post in the customer service section - it's a week old and clearly still under warranty

Definitely ring them, its not some cheapo PC! You shouldnt have to be farting about that much when you have just forked out that much on a system.

By all means do all the things they ask in order to diagnose and rule out possibilities but its not something you should juat be putting up with at all.

As above - lots of things to suggest but you've paid for a premium, overclocked, pre-built system with a sparkly, but, conditional warranty.

Ring or use their customer services forum - they may offer some simple troubleshooting ideas for you to try before you pack everything up - but at least it will all be done within warranty voiding rules.
