Re: USB port malfunction?

I have the same computer and had the same problem. I re-installed everything, returning the PC to new/out of the box condition. This didn't fix the problem. So, I decided it could only be a failure of the onboard USB controller.

I ordered a new USB 2.0 PCI Card (low profile size for the small case) from StarTech for $20 (ordered from

Installation instructions are vague, so, if you're running XP or Vista, there are one or two important things to do before placing the card in your machine.

First, go to the hardware manager and uninstall the modem, since you'll be removing this from the one and only PCI slot. Second, DO NOT remove the current USB controllers, rather DISABLE them (disable the top two lines on the USB tree list -- This will make the USB Hub and Unknown Devices below those disappear). This will allow XP or Vista to properly recognize the new StarTech card after install and install new USB controller drivers rather than trying to use the existing ones.

By the way, if you're running XP or Vista, you won't need to install the CD that came with the StarTech card.

So, this solved my problem. It's a $20 fix, but necessary. I hope this info helps.

My computer freeze and restart randomly

If the PSU power supply units fan is not working the PSU is faulty
Test all power and data leads that attach to your hard drive IDE,SATA
the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have secure dust free connections and are not faulty or just replace them they could be faulty

motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail

make sure all leads that are attached to your drives dvd\cd floppy have secure dust free connections and are not faulty or just replace them they could be faulty a computer needs

power and data to travel through every working device and to continue its cycle and have an end so any faulty leads will end up with a computer error

even something as small as a faulty power lead or fan lead can cause you problems

computers need all of the data and electrical current to travel through every working device and to have an end to be able work properly

make sure ram modules and cmos batteries have dust free secure seatings and cmos battery has charge some motherboards cmos batteries are soldered in

you might not have enough computer ram

not having enough computer ram will run your computer over its limits putting to much strain on the CPU central processing unit and can cause memory dumps

you might have to many programs trying to or accessing the internet at the same time
scroll to bottom toolbar (bottom of screen) right click select task manager

applications you will see whats running
if you see anything you dont need running select end now and you might uninstall that specific

program if you or computer does not require it to run and
some unnecessary programs that could be jamming up your computer

also under processes see what is ticking over in the background again if you see something you
dont need to be and users you will see who is using your computer

you might need to add more computer ram
if you're not sure if a module is right for your system use the

Crucial Memory Advisor tool for a list of guaranteed compatible modules. first you will need to select the manufacturer from a drop down list then select your product line

from a drop down list then select the model then click find it will take you directly to compatible ram also you will have an option to scan your system
you should always ask for a guarantee on the compatibility of the ram before making any purchase

might be getting hot

check you CPU make sure its securely seated and has thermal grease

hope this helps

I have 3 usb ports( two at the back and one on the

Check to see if something else will work on the side port. It may not necessarily be a dead port. Just something you should know too; I used to work for Wal-Mart in the electronics department and they had to recall all their firefly flash drives because they had a tendancy to malfunction. Try using it on a different computer, it might just be a dead flash drive. I hope this helps your problem and I hope your flash drive didn't have anything too important on it :x

USB suddenly malfunctioning on Dell TOwer

It does sound like your ports on the front might be bad. They usually connect to a seperate port on the motherboard than the rear ones, and I have seen devices short out the front ports, such as a USB music player.

You can remove the ports on the device manager, and they should come back ok, without worry. However, I doubt that is going to help the front ones. I think you have a hardware problem.

If that is the case, the easiest solution is to get a USB hub, and run a USB cable from the rear, to the front of the computer.

How to do to install web cam saic4007/37?

Webcams are usually just plug into a usb port on your computer, older ones prior to usb used a serial port. It's the software that needs instalation, if you didn't get software with it, you can use it with msn mesenger Icq, or any of the popular messenger services, or myspace, any application that uses video will seek out our cam. Also most photo programs and some email programs like comcast have video email, it just finds your cam and you click on the icons.

My usb mouse has suddenly stopped working

Your USB ports may have become dissabled by accident
got to your system bios and see if your USB ports are enabled

If your USB ports are enabled check to see that they have an IRQ assigned to them.

if your USB ports are enabled and have an IRQ assigned to them check to see that

"Legacy USB support" is enabled.


if the mouse still does not work , you may have dammaged USB ports , or simply a defective mouse.

Test print page error says printer is not on line. Paper advance works and power is on. Drive error says not enough information.

I suspect your printer port is dissabled in the bios , tripple check to make sure the printer port is enabled and let me know what happens. printerport IRQ = 7

if this is a USB printer , tripple check to see that your USB ports are enabled in the bios and have an IRQ assigned to them , namely IRQ 11 which is the default and you need not set it manualy.

Use the Primary USB ports , not the extended ones as they may be dissabled by accident or have faulty wireing.

let me know what happens.

USB Ports

one way would be to download and install latest device drivers from the net. it should help.. if you are using win XP, there is likely a BIOS or Windows configuration problem. On some computers there is a configuration option in the BIOS that asks whether an IRQ should be assigned to USB. Although the option's actual wording varies among BIOS manufacturers, you must enable this option by setting it to either On or Yes (depending on your BIOS manufacturer and BIOS version). Otherwise no USB devices will work on XP. A problem with Windows XP’s USB Controller configuration can also prevent any USB devices from working. To determine whether the USB controllers are working properly, open Device Manager and expand the Universal Serial Bus Controllers node. Beneath this node, you should see a USB Universal Host Controller and a USB Root Hub. Depending on your PC, there will either be a USB Universal Host Controller and a USB Root Hub listed for each of your computer’s USB ports or a USB Universal Host Controller and USB Root Hub for multiple ports
