Mistake

Hello TSF people!, this is my first post here, so, lets get to the point (ill try to sum it up for you guys the best i can with my crappy english... so get ready for a long *** story...)

This was my previous rig:

Intel Dual Core e5400 2.7ghz
XFX HD4850 512mb gddr3
Biostar g31d Mobo
2GB Kingston Ram DDR2 800mhz
450w PSU with two +12v lines, one with 16a and another with 14a
Two SATA Western Digital Caviar Blue 500gb
One IDE Western Digital 80gb
One DVD Writer

And with this combination running for over a year of heavy use in all terms, including gaming i never, ever, had any complications at all.

NOW.
Three days ago i bought the following:
AMD FX 4100 3.6ghz
Asus m5a78l-mlx
4gb Kingston RAM DDR3 1333mhz CL9

Thing is, i installed the CPU and did the swap properly of the parts (mobo, cpu and ram) to my other rig and everything turns on and works...
(no thermal compound, yet, tho, i was going to add it but since what happened, ill wait, but anyway, there's no temperature problems at all, cpu remains below 45ºc and gpu below 60ºc, its -0ºc over here)

Now, the first time i booted up to see if i didnt screw anything, i only plugged the mobo, cpu, ram and nothing else, no gpu, no hard drive, no dvd reader, didnt even conected the frontal usb and audio, and i proceded to boot up from a Live Ubuntu via USB, and, i noticed two things:

1. the PSU starts doing this weird frequency noise -that some people told me is a Coil Whine, not sure if thats it what im getting here but well...- when the OS loads, its constant and it changes its volume a little bit from time to time.
I have no idea why, it gets specially higher (not "omfg shut that thing down" high at all, but its annoying, specially since the case its right next to my ear) when i move the mouse drawing with the selection or i use an application, like a game and such.

And 2. the Audio didnt worked, even tho my old rig had the same onboard sound card, and it worked perfectly when i ran it plug and play in any linux.

I just took for granted that was normal and the audio could be solved in Windows, even tho its a shame since im a big Linux user.

So i proceded to connect one hdd and the dvd reader and installed windows x64 (also tried x86 later, same results), after the installation, the coil whine was gone but i did noticed that the onboard audio wasnt working with the plug and play drivers either and same with the LAN driver, so i proceded to install them, rebooted and two new things happened, audio and lan were working but the same "coil whine" or whatever its called started to happen again, and a little while longer the sound board begun with something else:
The Realtek CP was constantly spamming the "new device plugged" and instantly unplugging it, and so, and so, in a repeated loop.

Leaving me to unplug the speakers to stop it, i tried with speakers and even a mic in all three of the plug spots (green, blue and red) to see if it was only the green one, but no, it just kept on doing it.

The coil whine sometimes it stops its constant sound, only doing short bursts now and then depending on what i do, and resumes whenever he pleases, but its always there.

I did connected my 4850 later on to see if my PSU was the trouble and everything went well, no bsod or resets, played a few games i had on my hard drive such as MW3 for a while, and a few other games (Mass Effect 3, Stalker Syndicate, STALKER Call of Pripyat, Dead Island, Star Wars Force Unleashed, Dead Space 2, everything maxed out, no problem) without any trouble except the coil whine, and, obviously, no sound...

So i just freaked out and did a fast swap of hardware to my old Intel rig to see if my psu was definitively going to die and no, the PSU remained quiet, did a swap again to the new FX rig, again, without the 4850 on it, did the same as before having the same results: sound card freaking out, so basically no audio and the coil whine.

So Here are my questions:
Is my PSU broken or something?
How comes a more power loaded rig gets no coil whine but a lighter rig does?
Is the new motherboard broken? should i RMA it?
Could it be that the PSU broke the Motherboard?


Imma try to get a dedicated sound card tomorrow to see if this fixes it, but if i dont get one ill just get it to the store and show em, and ask them to fix it or change it for a new one, it surprises me cause its a brand new mobo, processor and ram and except for this things, everything works fine.

I know my current PSU is not good for the FX and 4850, and im planning on changing it for a brand new one soon, but ive been told this PSU can hold up for a while...

Right now the audio doesnt detect any speaker, mic or headphone, i just plug em and nothing happens...

Here i recorded a few vids so you can see what i mean, heres the old rig when i plugged it in back to check if the PSU was broken, no coil whine whatsoever coming from it, everything was working perfectly, just like before the swap to the new rig.

Here i swapped to the new rig and tried the live ubuntu getting the coil whine, and no sound:
VIDEO0038.3gp | PutLocker

and here i installed windows 7 x64, no coil whine, sound or internet, then i installed the drivers and the coil whine returned and the audio CP started to flip out.
Here you can see what the Realtek CP does first hand:

Hope you can help me out, thanks beforehand for your words, sorry of it was too much

big hug, thanks for reading.

PS: Heres a recording before i did the swap to my old rig to check on my mobo, just in case you cant hear the coil whine on the previous videos, you can in this one:

what is the make of the power supply?

With the whine noise are you sure it is only with the new parts and not an intermittant issue?

motherboards dont make a noise as they have no moving parts but sometimes the capacitors can make a slight whine.

Sorry I have not downloaded any of youir videos as I don't download from places I don't know are 100% safe for security reasons.

Yes, if you see the videos i uploaded youll see that only happens in the new rig.

Its the PSU...

I assure you the videos are safe bro, i recorded them with my cellphone and uploaded them to putlocker cause its free, downloads really fast and doesnt have any restriction between downloads, im not trying to infect anybody.
Look at the file name if you dont trust...

I think you mean brand, right?
its bangho, its a national brand, ill be changing it really soon for a better one, a Thermaltake probably since we dont get that many brands around here.
Still, its not a bad PSU, it does have 6pin pci connectors, a more than decent +12v line, and around 70% efficency.

Its a low quality generic psu, it doesn't even make it on the Tier structure of power supplies.

Power supplies are measured in Tiers with Tier 1 being quality and Tier 4 being crap.

Seasonic,xfx and corsair (not the builder or gaming series) are the best. If you go for a thermaltake power supply make sure it's the tough power series.

Ok so i just found something out, the coil whine can be changed when i switch the power plan to the highest performance and dissapears if i choose balanced or economy, i guess is based on the cpu load, since in the power plan you can change the percentage of cpu usage.

you mean the power from within windows?

If so then that means the psu is struggling, can you post the voltages from the BIOS if the BIOS is locked download CPUID hardware monitor and post a screenshot.

your 12v voltage is a bit low but within spec read this link on how to use the multimeter https://www.techsupportforum.com/foru...er-151526.html

Broken heatsink to MOBO
Hello I recently was putting my heatsink on my mOBO when I tightened the screws to tight and two of them broke. They are now in it stuck and can't get them out. If you know how to get them out please inform me. If I need to use some parts from other MOBOs I have lots of them. Thanks

Fans wont stop - Mobo or PSU?
Starting a few months ago, when I would shut down Windows, the case fans plus CPU and GPU fans would continue running (at a lower speed, since it's much quieter than when the machine is running) for a few minutes after everything else. There did not seem to be any power going to the hard drives or...
