Looking for Computer Hardware Specialist

[Reiiyna]

I am trying to find somebody who ACTUALLY knows what they are talking about to help me solve this strange little issue i have been having with my PC for a while now:

Before ANYTHING even loads, within a split second of pushing the power button, my computer begins to make an extremely loud noise akin to a buzzer going off, or some kind of warning buzzer. I have double checked everything within the computer to ensure everything is wired up correctly and see no faults. I have tried looking through google a couple times but nothing I have found is the problem I seek to fix. If anybody who knows what they are talking about (i say this because I don't want my PC to be in worse condition if somebody inexperienced says something that SOUNDS like it makes sense and i try it) can help me, I would highly appreciate it since I refuse to dish out $50 an hour for some guy to probably tell me it is something simple.

We talking buzzer as in internal PC speaker, or dry ball-bearing on a fan on cold boot?

95% likely bad ram

Sounds like something is blocking your CPU fan from spinning. Keep the case open when you power up and watch the fan to make sure nothing is obstructing it and it is able to spin completely, then make sure to keep cables out of its way when you close the case back up.

Edit: Bad RAM shouldn't cause a loud buzzing. A fan obstruction definitely will.

Edit2: Credential-wise, I'm a computer science major who builds and maintains all of his own computers. I've built and serviced plenty for friends over more than half a decade, and worst case scenario nothing bad is going to happen if you just open up the case and observe the CPU fan. This has happened on one of my machines before, and that loud noise is probably your fan straining to spin against whatever object is blocking it. It's typically just a cable from the power supply that bent the wrong way and ended up smushed against the CPU fan.

so is it just making the buzzing noise and working, or is it making the buzzing noise and the screen is staying black?

you've clearly never heard a memory fault post code before. Of course, this would only be the case if the screen is black.

I have, but there's a distinct difference between a memory fault post code and an obstructed fan motor in terms of what it sounds like. Given the description the OP gave, it sounds a lot more like the latter, which is also significantly easier to test.

Edit: For clarity, the post code should be loud beeps, while an obstructed fan is a constant buzzing. I suppose it could be either one, but needs clarification from the OP.

without hearing the sound I cant be sure, but awful buzzing sounds are generally created from the power supply or fans, if its coming from the internal speaker however it could be anything from bad ram to bad motherboard

is the computer still starting up after the noise is made? if so its most likely a fan, try and turn the computer on without the side and and see if u can pinpoint the sound

if there is an internal speaker hooked up to the motherboard take that out and try and turn it on and see if you get the sound still

you are going to have to try multiple things until you pinpoint the cause, these are the easiest places to start

a memory fault post code is nearly always a series of beeps in morse code style, however bad RAM can still cause a boot failure before even reaching post, which could cause the speaker to let out a painful wail

So it's not 'beeping' but rather 'buzzing', and very loud?

Some graphics cards that need their separate power connection usually (or often, every one of them I have ever had did) make an awful loud noise if the connection is not... connected, or the Power Supply is not providing the power thru this connection.

Also like others, I'd ask what happens then?
Does the box actually start up or what.
