Coil Whine after dropping pc

[tobiaskallevik]

I started hearing some coil whine in my desktop after I dropped it. The PC stood in a 45 degree angel when I lost grip and it hit the floor. What could couse this coil whine. I now have coil whine on both my gpu and the motherboard around the cpu area. The motherboard coil whine might have been there from before. It is a few weeks since I dropped it and it has worked since then. Should I be worried that it might stop working after a while?

Dont worry much; if it works perfectly for 2-3 months straight after the drop, then its absolutely fine. And about the whine, every person gets overtly cautious after dropping a valuable thing, and as a result starts focusing on minute details. So, just make sure that everything is working perfectly by doing some stress tests like prime95, intel processor diagnostic utility or passmark tests or geekbench benchmarks; select any one benchmark tools and if there is no error then its most probably fine.

I use AIDA 64 is that OK?

Yeah AIDA 64 is perfectly fine and its a very good tool to stress test systems.

ok thanks. Also i had this other issue. When i pluged the powercord to my psu amd than flipped the powersupplay switch on the fuse in my room broke. My psu is a corsair rm750x 80+ gold. I didnt have many electronics things on in my room at the time. I turned the fuse on again and tried turning on the psu again without any problem. I ran AIDA 64 for abou 10-15 minutes and the pc worked. Could something in my pc have been damaged by this?

Hmm, by turning on the PSU, the MCB fell means there was overvoltage. I think the socket or the wiring in that particular area needs to be checked. But it seems that everything is fine.
Generally, the the power phase design of the motherboard gets affected, making the pc to not post and keep restarting. Other issues that occur are frying up of pc components, PSU going bad.
But dont worry much as the corsair RM750x is a good PSU.

MCB fell? When i turned it on the fuse/breaker in my room truned off.

Thats what i meant by MCB. MCB means Miniature Circuit Breaker; Fuse cant be turned off, there is a metal piece inside a fuse which melts in case of overvoltages and needs to be replaced.

Since coil whine is something actually vibrating / moving it would make sense that it happened after it was dropped. Something coming loose would not be a surprise. Other than being annoying, its not a huge deal, it won't necessarily harm anything.

OK, but do you think I need to stess about any of these things? (the coil whine coused by the fall and the fuse thing)

Im my opinion, if everything is working perfectly, don't worry much. I would advice you to make sure that the GPU is properly seated on to the pcie slot, all the sata cables are connected at both ends. The coil whining can also come from the HDD, mechanical HDD's does that. And remember to always always always use a spike buster, some examples are Cyberpower , Huntkey, etc.

I don't use a surge protector. Will this effect anything?

You should always use a surge protector. In case of overvoltages, for eg., during lightning and thunder storms, it can save your components.

OK, but will it effect this?

A surge protector will not stop coil whine, as I mentioned coil whine is actually something vibrating, causing an audible noise. I suggest you google coil whine and what causes it perhaps you will get a better understanding as you don't seem to understand where the noise is coming from right now.

A surge protector will not stop a direct lightening strike, no MOV will. If lightening can jump from the ground to the sky it will arc across any fuse, breaker, or surge protector you can buy. That being said you should still buy a quality surge protector to plug your PC into, its cheap insurance to protect your PC from power surges on the power lines. Its just an extra layer of protection on top of what's built into your PSU and MB.

When you dropped the PC it is likely a coil or transformer actually was knocked lose and now it vibrates when power flows through it, causing your whine. It doesn't make it bad, just annoying.

The noise is coming from the cpu area on the motherboard and the gpu

 

[Mr5oh]

It doesn't matter where the noise is coming from, even your CPU makes nosies that inaudible to humans.

You could try unplugging unnecessary hardware one by one to try and isolate the noise. However once you find it unless you isolate he actual component and can repair it, unless you are ready to replace that piece of hardware, you are stuck living with the noise. If it works I wouldn't worry about it.
