Computer Makes Bhup bhup bhup sounds when i spam click my mouse in games

At first I wasn't sure what you meant, but then I remembered a similar situation for my PC when I spam click during high load.

I believe it's just an audible warning about too many messages for the PC/Windows to handle in a timely manner. Potentially the clicks that cause the noise are ignored by the PC. Just speculation here, but I've only noticed it on my PC when my CPU's load is too high and I'm playing something like an FPS whose priority is too low on the list.

Yeah, it happens all the time to me when playing FPS games - cant be my CPU load, my computer has never gone above 50% while playing any game. my mouse clicks wont go though while i have the keys pressed and it makes that sound but as soon as i release the keys the mouse clicks will go though.

if its a hardware sound like you can hear it inside your computer as opposed to through your speakers it could be a hardware issue, or just incorrect version of your mouse software being installed, you check BIOS yourself if your up to the task to check for errors
just don't take it to geek squad, its a money waster

It comes though my speakers, so software i guess. dunnno how to check my bios or what i would be checking for but all the software for the keyboard and mouse are up to date. we dont have geek squad in aus

press like eight keys on the keyboard at once and hold them down, does the same beep happen?

Yeah pretty much.
