Computer crashed,i changed the hard drive and now i have no sound

Either you broke the connector or crashed the head. You could crack the case open, buy a new empty enclosure and see if the drive will work in it. Otherwise if the head is crashed, replace the drive.

Could be a couple of things. First thing I'd suggest is taking the actual hard drive out of the enclosure. If it was just the bridge controller in the enclosure that burnt out, then you might still be able to gain access to the data by connecting the drive directly to a computer or try it in a different enclosure.

If that doesn't work then it may be a more serious problem. I could be that the controller board shorted out. Simply changing the board with another one from a similar hard drive won't work, because there is adaptive data that is stored on the controller that must be maintained with the original drive.

The other problem, and it's something we see often in these drives, if there was brief cut to the power, sometimes the heads won't park all the way, and they seize to the platters. This prevents the drive from spinning up. If that is the case though you would hear a faint buzz buzz sound coming from the drive. You'd also hear that same sound if the spindle motor was seized, but since you didn't say the drive was dropped or bumped, I doubt that's the problem.

Hi!
I think I had this kind of issue before on my computer. I sorted it out. First I check the motherboard and wiring inside if there are any wires touching the fans because of the buzzing sound. Found nothing. I noticed that the buzzing sound came from my hard drive. It seems that it's not getting enough power that's why its struggling to spin. What I did was I changed my power supply to higher wattage and everything was fine after that. You can give it a try though. If it still the same issue, you might as well try a different hard drive.

Regards!

These symptoms indicate a possible hardware failure.
Take the computer to a repair shop where they would replace it for free incase it is still in warranty.

Sounds like the Hard Drive crashed. Remove the HD and test it in another computer to be sure.

If it was running at the time it fell, the heads crashed into the platters, and the buzzing you're hearing is the dents left in the platters spinning by 7200 times a second.
Not good. Likely will need a professional service to recover the data.

Try this Double click on the volume control icon in the system tray.Click on "options"--"Properties".Select Line-in and Mic.Mute them. I hope this solves your problem.

I was afraid of that. The speaker system is only half in the monitor the other part(Amplifier section) was in your old computer. Here is a possible solution. Buy an external sound /speaker system. The amplifier comes with it and many can be had at a reasonable cost at **** places as  Walmart , target ,etc. Sorry. but the speakers on  your monitor, I believe ,  will not work with you new computer. Sorry. 

Your hard drive has crashed but here is what you can probably try. Take off the hard drive. Put it into another system (a friend's computer or something) as secondary drive. See if it gets detected in the BIOS. If it does, you can try and run a application like Recover my files to try and salvage your data. Hope this helps.

hello

okay i think your base is too full.

turn off the base of your speekers and then try to play a song or a sound...

if not go to control panel and then sounds and lower down the base volume bar
