Dictation.Nerformance,
there are still a few more things you can try. Did I see somebody already gave you a link to the program that tests all your USB ports? If so, how did that turn out?
Here are some other possibilities of things you could do at this point to try to determine what the exact problem is. Did you give us the exact model of your desktop computer? And does your desktop computer have an integrated graphics card and are you using it or did you add the dedicated graphics card into a PCI slot?
Did you recently make any changes to your hardware? Have you recently opened up the inside of your computer to clean things out? Is there a possibility you could of disrupted some cables or jumpers that are needed for the USB connections? In other words, there may be some kind of mechanical problem that occurred when you opened up your computer to make some adjustments or changes.
The other possibility is that somehow the proper drivers for your USB devices have been lost. That is very, very unusual. That would suggest there has been some kind of hostile mountain where he installed in your computer that just attacks your hardware USB ports and nothing else. Again, that is very rare.
Let's take a look at some other things that could be done only for the purpose of doing a diagnostic, nothing else.
Windows itself, when it installs, finds appropriate drivers for most of the hardware on your computer. Additional hardware drivers are found on a CD that would come with the motherboard, if you had purchased a custom motherboard and built the computer yourself.
But if this is a standard off-the-shelf computer made by Dell Hewlett-Packard or one of the other major manufacturers, all the drivers would've been preinstalled and are also available in the recovery partition.
At this point I'm going to ask you if you do have an installation DVD for the first version of Windows you are now using. If so, you could try this as only a diagnostic and not as a cure-all.
Using the tools you find in your control panel you will find someplace where there is a disk management program and is allow you to shrink the size of one or more partitions on your hard drive. Avoid doing anything to the recovery partition. Leave it alone. Instead, try to of one of the other partitions, even the Windows boot system partition can be resized to some extent.
The objective here is to make enough room available on the hard drive to install a fresh copy of Windows on the free disk space you have made available after shrinking one of the partitions. If you're system has a installation DVD, you can use that DVD to install the same version of Windows on another partition. But if this sounds like too much trouble for you, there is an alternative.
What you're trying to do is to see if a new installation of an operating system will properly install the USB ports on your motherboard. Ideally we would do this with Windows, however we can also do it with Linux. The advantage of using Linux is there are some versions of Linux that are very small and can be installed rather quickly and don't even require hard drive space if you ask for the demo version.
One version of Linux that I use quite a bit for troubleshooting is called Puppy Linux, which is available for download free and fits very nicely on a CD. Will boot up from the CD after you specify that you want your computer to boot from the CD.
http://puppylinux.com/download.htmlUpon startup that would last for a couple of simple options, but you should be able to just ignore it and go ahead and get it up to where you have the Linux graphical desktop. Now at that point it should be pretty obvious whether not your keyboard and mouse are working. Because of your keyboard wasn't working you wouldn't be able I have seen the questions that Linux would ask you upon boot up. Likewise with the mouse. If the mouse is working you'd be able to move around on the screen.
Of course, in order to prepare a Linux boot CD you have to have access to another computer they can get to the Internet – has a CD-ROM drive that can burn the CD from thel Linux ISO file.
Now if you are able to get another operating system up and running to the graphical desktop and the keyboard works, we have established that the problem apparently is something to do with the operating system not being installed properly or got damaged by something. Even at that point it would be hard to tell what damaged it, but at least we would know that reinstallation of the operating system should solve the problem.
But before you reinstall the operating system, you want to make sure that you have some way to recover the data you need.
Does this sound like something he would want to try?
At this point I am almost out of ideas. But there is one more. You could go purchase a small PCI card that has four USB ports on the back panel. These are usually sold for less than $20 and can be found at this Newegg or Amazon or maybe even at your local Walmart.
Walmart USB PCI card.That's the best I can think of at this time.
End of dictation.
