Question about Mach Speed P4MBMS Motherboard

Sound Starts on Then Goes Off Randomly


I have a problem with my audio. When I start up my computer, sound works and everything is going good. Then, all of a sudden I'll play a random sound or I'll just be on my computer for a while and all of a sudden the sound goes out. But, instead of hearing nothing out of my speakers, I hear this muffled static sound coming out of the speakers. And, every time my hard drive starts to think harder and load, the static sound coming out of the speaker gets louder. I tried switching speakers but I had the same problem. I think it's an internal problem. I checked my sound card and every thing with the sound card is OK. So, since it's not the sound card, I don't know what it is. By the way, I am using a P4MBMS motherboard.

So, to sum up my problem and question: I start my computer each time and the sound is on. Then, all of a sudden I run some random sound or I have my computer on for a while and the sound shuts off but I hear a staticy sound. My sound card and my speakers aren't the problem. What can I do to make the sound stop randomly going off??

Please respond and thank you,

    Im having the same problem. I start my pc up i have sound but when i click a song or play a game there is no sound. I recently changed my processor, cleaned my registry and prevented some things from starting up. Anything you have done to your pc?

    Nothing yet, but I am looking into changing some aspects of it. Did you fix your sound problem? If you did, was the problem with your motherboard, with your sound card or with your drivers. Please let me know.

    Know what? I tried installing the newest audio driver for my motherboard and, all of a sudden, the sound popped back on and it hasn't stopped working since. So, it was a driver issue. Thanks for your help, though. That makes me feel sure that the sound problem is completely fixed.

    Now, onto why I can't complete installations of new video drivers....

I actually fixed the problem. It was a driver issue. Try this with your sound card program. I opened up the program in charge for sound. In my case it was soundmax. And pressed the load defaults button and clicked apply and everything started working again. The same thing happened again after a while so I pressed defaults again and it worked. But It happened again so I uninstalled the drivers and updated them. Everything was fine after that. Now I have a problem with my

Hope it helps.

Car alarm just goes off randomly

Check the battery in the vehicle and the battery in the actual keyfob itself. Sometimes when one of these are low the alarm will randomly sound. The random alarm sounding is typically an indicator of a low battery somewhere. What is the year make and model of the vehicle? Some, like bmw's, have sensors under the hood, on doors and windows that get stuck and randomly sound the alarm. Please Advise

Hello! "no audio device is installed" is my

If there is no device in Device Manager and the correct driver does not install, you have a hardware failure. The sound portion of your laptop motherboard may be malfunctioning; probably is. As it is a notebook, installing a new sound card is not an option. You could have a new motherboard installed, but the cost of that starts approaching the cost of a new notebook. If you cannot live without sound, time to look at a replacement. These days, PCs are made to fail in about 2-3 years either by a failed motherboard or a failed hard drive. If you get past 3 years, you are lucky. Backup everything while you can. I use an external USB hard drive and the Free version of Macrium Reflect to make a disk image; that way, I save all of my data as well as software programs.

Computer speakers do not work

Maybe you need to reinstall the driver for your sound card as what ever you installed may have currupted the original sound driver.
I hope this helps.
Have a good day and good luck.

Hello virac80,

Does your HP desktop have a built in speaker or is it connected to an external speaker system?

You could also check if the audio jack is properly connected to the audio port at the back end of the desktop itself.

Just to be really sure, you can go to your Device Manager & check if your sound card is working fine.

For you to get to Device Manager, click on the Start Menu button, then drag your mouse cursor on top of your My Computer icon, right click that icon then go to Properties.

Choose the Hardware Tab, then choose Device Manager.

Find Sounds, Video & Game controllers. If you don't see any red X mark or exclamation point, everything's okay.

Just double check on your wires if they're all properly plugged in to the correct ports.

Sound stops suddenly

Alright, so wait, explain that again, It stops working when your using it, or when it goes into standby?

It starts working again after what? When you come out of standby?

When going into standby, the system goes on low power may cut the power to your speakers.

Check your Power settings.

RIGHT CLICK on DESKTOP> Select properties, Go to screen saver Tab and click on the Power button, then check all the power options such as when it goes into standby, how long till it does and adjust them to your preferences, also make sure Hibernation is turned off as well, when it goes into Hubernation, it cuts almost everything.

Give this a try and let me know,
good luck

Speakers stopped working

Hello there!
It sound a power adapter failure,
check your speakers for power failure, or bad connections,
check also your sound card, mixer, and drivers.
perhaps if a onboard sound is disable for some reason.
check that too.
Good Luck
