Question about Computers & Internet

1 Answer

The USB and ps/2 ports are not working on power up. the keyboard and mouse are not recognized on boot up. The PC boots as normal to the desktop with no problems. All was working fine until i started messing around with a sound blaster card and upon turn off one time the above fail happened. Now when i switch on the PC I can hear a beeping noise which I'm guessing is a fail code or something. I'm guessing it's a bios fail but if I'm unable to use keyboard or mouse i cant really do anything..bios info is: Phoenix Bios, D686 bios...motherboard model is: MS7187 ver 1.A...thanks lads

    Thanks JimHillTx for taking the time to look at this. I tried all you suggested above and nothings changed. I did get the screen allowing me to go to safe mode etc but as the keyboard doesnt work then thats no use. What I did notice is when i switch off the PC the keyboard and mouse light up as if they were working. The num lock light can be turned on and off but not the caps or scroll. But when i switch on the PC they switch off. I found a PCI usb card and the power seems to stay when switched on so i'll try a usb keyboard and mouse with this board tonight and see if anything changes. Strange one.

I assume you have by now taken out the sound blaster card, I hope. The beeping is a code that tells you what the problem(s) are with your computer. Just taking out the sound card will be a start. If you had an onboard sound card and did not disable it first, then that is what started your problem. Try booting up and pressing F10 to get to the set up screen. make sure your ps/2 and usb are turned on. if you can't get it to work on your usb keyboard, borrow an old one and do the same thing. hopefully nothing permanent has been done. your bios should straighten back out. if this does not work with the old style keyboard, then open your case, you will have to find the reset jumper, very hard to find unless you have the board manual, or just lucky. Not able to do that, then find the backup battery, will look like a watch battery. Take it out carefully and leave it out for couple of minutes, reinstall and should be good to go. pulling the battery erases all your settings and returns it to bare stock settings..... let me know if more come up

Are your devices wired or wirelss ? Have you tried another usb keyboard ? You could try booting up the machine, then switching the devices to another usb port and hope windows will reconize them. Last resort would be getting a real PS/2 keyboard at thrift store or if your really stuck, boot with a live-CD then you should have mouse and keyboard to try to copy drivers manually over to the windows folder.

Keyboard locked


If they are PS/2, power off make sure that they are not plugged into the wrong port, they will fit....but won't work that way.

If they are USB, try booting into safe mode and see if they work there

Pressing [F8] repeatedly on boot is how to get the Safe Mode options to appear, then use the Arrow-keys, (up or down,) to highlight a Safe Mode option, then press [Enter] to select it.

OnBoard USB Ports Not Working and No PS/2 Ports!


When you boot the machine does it tell you what key to hit to get into the BIOS or System Setup? If so, press it. Maybe you need to try another keyboard if it won't allow you to press a key to get into the Bios or System Setup.

I want to change keyboards


Hi Richard,
most enhanced keyboards need a specific driver to run.
Go to the manufacturers website to download the driver. or search on Google.
You might also have to enter BIOS (accessed when the computer is booting..look for a message that tells you how to get into BIOS, or look in your user manual). Often it can be accessed by pressing the DELETE or F1 key just after you power up. The option in BIOS you may have to change is something like "enable Legacy support for USB".
Have you tried looking in the Dell support website? As you just recently(?) bought this, you can ring up Dell support centre and ask them to help.
Cheers,
Steve

A lot depends on where the keyboard and mouse are plugged in. I have seen in the past that the USB in the back works better than the front. Are these the original keyboard and mouse? If not, use the original until after Windows loads the desktop.

Keyboard not found


Is it a ps/2 or a USB keyboard? If its a USB keyboard it may be that the drivers won't load until you actually log into windows. Only fix is to boot with a ps/2 keyboard.

If its a ps/2 keyboard then you are probably plugging it into the mouse port. doublecheck your locations.

No boot no keyboard or mouse


First disconnect all external connections except video, see if system will boot normally (press the power button once on tower to shutdown)

If that works, then connect the keyboard only to the back USB port nearest the NIC. See if the keyboard works. If it does, shutdown and connect the mouse and try again. If it doesn't, try the mouse only. If you localize the problem to either the mouse or keyboard, replace that item.

If neither works, then reset the motherboard junper to reset BIOS defaults. the again, try them one at a time. If they still do not work, then you will need a mothebroard.

Usb issue


Do you have a ps/2 keyboard/mouse? Or a usb->ps/2 adapter. I'd say boot up normally and log in with the ps/2 keyboard/mouse. Then, from device manager, right click everything under USB and such and uninstall. Then right-click your computer name in the device tree and scan for changes.

Dell Dimension 3100 e10 ...usb won't work


Does the system respond to boot keys (F2, F12) when the DELL logo appears? If so the problem is with Windows drivers and probably can be resolved by reinstalling or rolling back the drivers, but how? Do you have access to another keyboard? Does the system have PS/2 ports? Do you have access to a PS/2 keyboard or adapter? If boot keys work, you could also choose F8 for Last Known Good Config (XP) or System Restore (Vista).

Have you tried different ports (front if using back or visa-versa)?
Try using just keyboard or mouse to see if one has somehow shorted. Also check the ports for any sign of damage.

Keyboard not working


Minimal information to go on. Since you didn't specify whether this is a laptop or desktop, I'll respond with the assumption that it's a desktop.

Power off computer.

Install new (known working) keyboard.

If that doesn't correct the problem, your issue is probably with the PS/2 or USB port your keyboard is plugged into.

If you are using a USB keyboard, first try moving it to a different USB port, then booting. If that doesn't help, try a PS/2 keyboard.

If you cannot get a known good (working/new) PS/2 keyboard to work in replacing a PS/2 keyboard, try a USB keyboard.
