Asrock mobo making horrible noise

[lonrot]

Hi there, my Asrock G41M VS3 R2.0 makes a very sharp noise while it boots and whenever windows is loading something. The sound does not come from the fans but from the motherboard itself, I don't know exactly what causes the problem. And I doubt this sound is natural.

Please help me out, so I can decide if I should return it to the store to get a replacement.

I uploaded this video including the annoying sound I stated before.

UPDATE1:

The sound comes from the PSU, not by the fan, as I made stop on purpose, more likely an electric connection to me.

UPDATE2:

Finally purchased the new PSU (ATX 600W 8cm, Over voltage protection: + 3.3v, + 5v, + 12v). Not a single sharp irritating noise, only the smooth sound of fans doing their job, I'm so glad! Thanks a bunch everyone, this forum was very helpful to pinpoint the issue.

Here's a capture, I hope this PSU lasts longer than the old one.

Re: Asrock mobo making horrible noise

its not the motherboard!!!! its your psu,very common problem with all motherboards,go in bios and disable intel speedstep or eist c1e c3/c6 states then see if noise still happens

you need to change to another brand of psu that doesnt make the noise,its caused by electrical interference(emi) by the cpu power saving

Re: Asrock mobo making horrible noise

That's so weird, my PSU didn't have that problem before I replaced the motherboard. The mobo I used before was intel socket too.

@wazza300 Speedtest is already disabled, other options in OC Tweaker are:

DRAM Frequency
DRAM Command Rate
DRAM Timing Configuration
Ratio CMOS Settings
Overclock Mode
DRAM Voltage
NB Voltage
VTT Voltage
GTLRef Voltage

Re: Asrock mobo making horrible noise

Take you motherboard out and test on the bench. Then you can pinpoint the issue much better. I couldn't tell much as there was so much background noise. disable all of the fans. What make and model is power supply?

Make sure everything is unplugged except essentials (monitor, video, keyboard, mouse)

Is that an emachines computer?

Good luck

@MarkJohnson You couldn't tell??? The sound is sharp, like tiny sparks (you can't miss it), the rest are just fans.

Re: Asrock mobo making horrible noise

I just switched to my HTPC rig and now I can hear it much better on my stereo system. It does sound like the power supply. I would run it anymore until you borrow or buy a Power supply to test with. I do however recommend a bench test to help pinpoint the problem. Even take off the power supply cover and inspect the insides for any caps leaking black goop all over. It sounds like one leaked all the oil and the coil inside is vibrating making the noise. Just be careful. If that power supply goes out, it may take out your motherboard, cpu, memory, and everything else with it.

Did you find out the Make and Model of your power supply?

Good luck

@wazza300 here some screenshots of my bios, hope you can lend me a hand.

VERY BAD SUGGESTION!!
You will instantly void your power supply's warranty if you remove the the outer casing.
You risk getting a serious electrical shock from the stored electrical charge that remains for quite a while after you have unplugged your psu.

Re: Asrock mobo making horrible noise

It looks like your psu is a cheaply made, no-name, bottom of the barrel unit that probably can't deliver anywhere near 450 watts.
There are many high quality, reasonably priced 500 watt power supplies make my Antec and Corsair and others.
Before you buy a psu, you need to read reviews from the best psu websites, such as JonnyGuru, HardwareSecrets, HardOCP, PCPER and TechPowerUp. Avoid all review sites that only use a DMM (digital multimeter) and/or software monitoring programs. Some major brand name psu manufacturers make low end power supplies that don't put out their advertised power and sometimes have excessive electrical noise (ripple) and/or voltage regulation that barely meets industry specification limits.

Buying a cheaply made psu can possibly kill your hardware.

Re: Asrock mobo making horrible noise

Sorry, I figured this was a very old unit and didn't think about the warranty.

also, the psu can store a lot of energy, you wouldn't believe how many pc techs die each year from working on computers. They are usually working alone when this happens and have no help.

Normally I pull the power cord and tap the power button a few times to make sure power is drained and never touch any of the components directly.

So, if you want to be safe just try to borrow a psu for a quick test and don't open the power supply.

I don't find anything on that psu at all. It has a few approval listings in the lower left corner.

Did you try to remove your components and bench test your system outside of the case? It could be a grounding issue.

Re: Asrock mobo making horrible noise

My five year old Antec EA500, 500 watt psu was one of the best performing power supplies in its class, with the following ratings:
Max load:
+5V ---- 20 amps
+12V1 -- 17 amps
+12V2 -- 17 amps
+3.3V --- 20 amps
-12V ------ 0.8 amps
+5Vsb ---- 2.5 amps

Modern systems need much higher current (amps) available from the 12 volt rails.
The iPoint psu has a much lower 12 volt current rating and isn't suitable for modern systems.
Use your old psu as a low tech door stop.

Re: Asrock mobo making horrible noise

it should be in the bios somewhere under cpu or advanced cpu configuration,c1e eist c3/c6 turn them all off and see if noise stops,as for psu theres nothing wrong with it at all or your mb,its just some combinations of power supply and motherboards produce this electrical inerference noise,i had exactly the same thing with my psu in sig but its a cheap unit,switched it to another psu and noise stopped so i know its psu thats causing it

this is the model psu i switched to and can confirm no noise at all on three different motherboards problem is i dont think they ship worldwide you would need to ask

Re: Asrock mobo making horrible noise

No offense to NovaTech, but have any quality psu review sites done a thorough evaluation on their models that include:

• ambient temperatures at least 40^o (C)?
• putting 20% - 100% loads on the psu to ensure that voltage regulation and ripple are well within spec?
• verifying that the power supply delivers 100% of its rated output and remain within spec?
• stress tested each model at 80% of rated load for several hours?
• tested for proper OCP (Over Current Protection)?

On this side of the pond, there are many customer reviews for cheap, POS power supplies that I wouldn't give to my own worst enemy.
Using a 150% dollar/pound exchange rate, it looks like the NovaTech units are reasonably priced.
Do they have a 5 year warranty?
