i bought this coputer from kijiji.ca and it is home built partially i am pretty sure.

i searched around 2 try and figure out why, but could not... message i got said the peripheral does not appear to be plugged in, also earphones dont play any sound either. What does peripherals not plugged in mean, do i have to open up computer? And also this isnt a big deal because i also have a usb keyboard, but the keyboard input does not work.

any ideas guys?

In the most general sense, a peripheral usually means anything that has the word "drive" in the name of it. That means things like Hard Drive, Solid State Drive, DVD Drive, and so on.

In this case, it sounds like the computer thinks you should be getting sound from such a device. It could be thinking about a discrete sound card if you have one of those and not just motherboard sound.

Also, do you know if your sound is being routed through your video card? If you have your sound traveling over HDMI into your monitor or something then it could be a problem with the way the video card handles sound.

If you have a video card driver that handles sound, you might want to consider uninstalling it and see what happens. Sometimes the generic windows drivers do better than the ones that get installed along with the video cards.

i know what u said prolly made alot of sense but i just dont get it, i am not great with computers and i just want my damn sound to work and my friegen keyboard port to work ahhhhh!!! thanks though, if there is a simple fix that i could understand that would ne great guys. I am currently contacting the person i bought it from but i'd like to resolve the problem on my own with ur help :)

Do you have a copy of the classified ad? I'd ask you to list the full specs of the computer, but like you said, you don't know much about them.

What operating system does this computer use?
Windows XP? Vista, 7? etc.

I'd like to know what the specs are. Whether or not the computer has a separate or integrated sound card. A simple way to tell this is by telling me where the plugs for the speakers are located on the back of the computer?

Are they like this? Or are they lower like the modem in the picture?

The sound may be a conflict of drivers (software that tells the parts in the computer how to work), or the drivers are corrupted, or not installed at all.

Download this program
http://www.cpuid.com/softwares/cpu-z.html

When you open it, give me the following information:

Under the Mainboard tab:
Manufacturer and model.

Under the Graphics tab:
GPU Name

Theres other stuff I could ask you to give me from this program, but I don't think they're really relevant to the issue.


The keyboard port problem, could be caused by physical damage (Example: a bent pin(s).. Which leads me to suggest, being more careful (or avoiding) classified ads such as these in the future.

lol, the seller informed me that desktops no longer have internal speakers, heheheh, i didn't know. So there is a green 3.5mm input at the back of desktop that works for speaker input.... it is 1 of 6 inputs at back. Speakers name: 1. High definition audio device 2. digital audio s/sdif high definition audio3. same as number 2.....Now some things i still would like to know are the following. There is a one headphone input jack and one mic input jack on the front of the desktop. It does not work if i plug earphones in it, how can i get this to work. Also, for the mouse and keyboard inputs, i found within dxdiag at start menu that the status is attached but controller/vendor/and product ID's are all n/a

cpu intel core2 duo e7500 @2.93ghz

so can ne1 help me get these things working, thanks.

LOL. I think I see what you're saying now. You were expecting the computer to play sounds without any kind of external speakers hooked up to it. No, the only "internal" speakers computers have now is one that makes beeping sounds.

The default color for the main speakers jack you want to use is the green one, FYI.

As far as the headphone jack on the front, its possible that it could be not turned on. You'll want to click the speaker on your task bar and open up the menu, (there are slight differences between operating systems)

Right click the speaker icon in the right hand corner of the computer screen. Click Playback Devices. Click the properties, and make sure the levels are up. You should find one for that jack on the front of the computer. Now its possible, that the computer may not be wired to that port on the front of the case, but again lets try to rule out the simple things first.

The mouse/Keyboard in Dxdiag show n/a because they are integrated into the motherboard.

If you want I can take a couple screenshots and show you what to check out.

hi, i tried your recommendations and found that there is a front panel audio device installed for headphones, yes. But it does not work still, there is no place to manage volume inside properties and device is enabled.Also the driver is up to date, i don't get it.

sweet i found out how to make the front jack work !!!!!!!!!!!!!!
for people that have same problem do this......

download: High Definition Audio Codecs (Software) at

http://www.realtek.com.tw/downloads/

after downloading and restarting computer

go to control panel and find realtek hd audio manager

then do what people say in the following link, somone actually posted a pic of what u need to do within the realtek hd audio manager.

Do your mouse and keyboard cords have little round plugs on their ends with about 5 pins? Or, are they rectangular plugs that fit into a USB port? The small round plugs are usually PS/2 connectors, and they would plug into the respective PS/2 ports, usually on the rear of your machine near the top. Note that these ports have separate mouse and keyboard labels, and usually are colour-coded purple for keyboard, green for mouse.

If you are plugging into the PS/2 ports, make sure your BIOS Setup screen has those ports Enabled. If you are plugging into USB ports, plug into ones on the back of your machine, and make sure they are Enabled in BIOS. You probably do not need to Enable in BIOS the "Legacy USB Support", but you can try it if you like.

: They are color coded purple and green, and when i plug the keyboard in the correct colour the numb/caps/and scroll lock quickly light up and then turn off and keyboard does not work?

Quickly light up and then turn of ... sounds like there is at least partial functioning - that's the power-on sequence of the keyboard itself. However, after that your system does not respond to the keyboard.

I just realized that, with no keyboard function, you can't enter or adjust the BIOS Setup. So, I would try two things;

1. Borrow another keyboard and try it, just in case your keyboard id faulty.
2. MAYBE the previous owner was using these two peripherals connected via USB ports (requires an adapter) and had the PS/2 ports DISabled. So, get an adapter that converts a PS/2 male keyboard connector into a USB connector, and plug the keyboard into a USB port to see if that works. Also try the second keyboard this way. Alternatively, borrow a keyboard already made with a USB connector on its cord, and try it.

this is not a major problem because i have a usb keyboard, but i like to have everyhting working if possible. I also have a usb/mouse...keyboard adapter that converts a usb port into a keyboard of mouse input. There is usb inputs so that is great, but i dont know why the keyboard input does not work? Also, what exactly are bios and how do i access them.

Its not a major problem. If you didn't have a functioning keyboard the computer could detect, you couldn't boot up your computer at all. Let alone BIOS.

As to what BIOS is, its an acronym for Basic Input/Output system. Without getting too technical, it is a mini operating system that is physically stored on your computer board that tells the computer to turn on the hard drive and look for Windows. It does other things, but thats a very simple explanation of it, I'm sure somebody could come into the thread and criticize my explanation and go into some overly complicated explanation. Hey, I could have done that, I wouldn't concern yourself with it unless you're genuinely curious.

As for why your keyboard port doesn't work, my guess is that its physically damaged, as long as you have a USB keyboard and mouse, I'd pretend they dont exist. If you find yourself short of USB ports, you can always get a cheap usb up, you can daisy chain them together (plug a hub into a hub) and end up with over 100 usable USB ports if you were so inclined. :pt1cable:

I confess, I told you a white lie on the keyboard port. It could indeed be turned off in BIOS (no promises), but I figured you are the kind of person who doesn't care how and why the computer works as long as it does. But I thought about it, and I guess its not fair to leave it like that.

It is indeed possible that the ports are turned off in BIOS, if you want I can walk you through how to check, again, I assumed you're content so long as a keyboard does work.

Sure.

Start by turning the computer off, and turn it back on.. As soon as it powers up.. immediately start tapping the delete key. This should take you into a blue screen with a menu.. This is your BIOS/CMOS (insert meaningless acronym here)

Some BIOS are different from others, so if delete key doesn't work, try F1 F2, Escape key, or F10 if delete doesn't work. (it should)

If you get into this menu, look for something like "Integrated Peripherals". And see if there is something "Disabled" like PS/2 connector. If its disabled, enable it. And save changes and reset. You can look around in there in case its not in "Integrated Peripherals", but thats where it ought to be if it is.

There may not be something like this at all, if there isn't than my prior statement that the port is damaged physically stands.

Don't change anything else in BIOS, this is the reason for my white lie, changing something that you don't understand could cause more trouble than it was worth to get those antiquated ports working.

so i tried it and under "boot settings configuration" was the only place i could find "ps/2 mouse support" and it was set to auto, so i set it to enable, that didn't work after save and exit, then i tried disabled and that didn't work, so i put it back to auto.... so i dunno, thanks for the help though, now i know what bios are and how to access. ne more ideas? Any more ideas? thanks.

No problem.
Nope, I got no more ideas, they're busted. If you find yourself short on USB ports, Thats easily fixed with something like this:

OP, if you are going to open the computer case to look inside, look carefully on the motherboard ("mobo") for the name of the maker (like ASUS, BioStar, ASRock, MSI, Gigabyte, etc.) and then look close by for something like a Model Number. Post them here, and that will help us find the manual for your mobo and give you advice on specifics. What nekultury said is right, including his caution not to change anything else by mistake. Let me add two notes. One, after you have made a change, you must use the correct keys (usually there are on-screen prompts) to Save and Exit. You also can Exit without saving, in case you are worried that you changed something you did not want to. The second: instead of repeatedly tapping the "Del" key, you can just hold it down until the first BIOS Setup screen shows up. But just in case your system does not use the "Del" key for this, watch the screen messages for a prompt about what key to press to enter Setup.

I see nekulturny pointed out you already specified the mobo, so there will be no need to open the case. My reading of your manual does not help much. It confirms that "Del" is the key to enter BIOS Setup. I also agree that the only mention I could find of PS/2 options is the PS/2 Mouse Support on p 4-33 in Section 4.7.2, and you already found that does not solve your problems.

I guess I'll agree with others - the PS/2 ports appear not to be working, for whatever reason. If you can use the keyboard and mouse via USB ports, that's your best solution.
