I'm trying to troubleshoot a computer for another person, and it has problems with USB flash drives. I just bought a brand new Sandisk Cruzer Blade 16gb for it, and even though it shows up when plugged in, it doesn't let you access the volume, format it, or place new files on it.
The same USB flash drive works just fine on another computer, so I believe it's a problem with the computer, especially since it has similar problems with other USB flash drives it is used with.
The only thing I can see wrong at the moment is that in the Device Manager, a device called "M-Systems Diskonchip 2000" has a yellow exclamation point next to it. Upon further inspection, it's an embedded chip device aqcuired by Sandisk, who make my USB flash drive, but it's still present when the USB flash drive is removed, so I believe it's a permanent fixture in the Device Manager, and was there before I bought the flash drive.
This device entry is not working because it hasn't been assigned a resource range, but none of them are suitable as they're all being taken up, apparently.
The computer is quite old: A Dell, with a Pentium 4 2.06ghz processor, 500mb of RAM, and a 30gb harddrive. It's still got a printer port, if that gives you any more indication as to its age. It's running Windows XP.
Is there anything that anyone can think of which could address the problem of these USB flash drives not working?

Are there any obvious solutions for a computer which won't allow more than 2 USB devices to function properly?
Wait... you said it was a Dell. Then you probably won't find much in the bios. Bleh.
When I mean uninstall the USB devices, I don't mean the USB mouse you have plugged in, I mean the motherboard drivers the computer uses to communicate to the USB mouse. Normally at the bottom of the device manager.
