After doing the microsoft troubleshooting,I restart my computer and the install box pops up at the bottom right showing its reinstalling everything (printer,webcam,camera,mass storage device,composite device,drivers and so on)then a box pops up showing this error(I did not have this error before)
C:\windows\system32\spoolsv.exe
Function address Ox77e7b825 caused a protection fault.(exption code OxcOOOOOO5)Some or all property page(s)may not be displayed.
And my mp3 player's are still showing same error.

[happyrock]

try rebooting again...are you still getting the spoolsv.exe error...
try using your printer

[cant]

printers not working,i will uninstall it then reinstall

[cant]

ok printers installed and working no more error from that

[happyrock]

click on start...run...type in services.msc...press enter...
scroll down to plug and play...set it to automatic and make sure its started...
try the mp3 player...
nojoy
shut down the computer disconnect a couple of usb devices like your web cam and mass storage device...
boot up and see if you can connect the mp3 player

[cant]

Plug and play was on automatic/started so I disconected everything one at a time,cam/camera/printer trying the mp3 player then plugging back in.Finaly when i disconected the printer my mp3 players worked!when I plug the printer back in the mp3 players show the error again.

[happyrock]

they probably are having a IRQ conflict or you may just have to many usb devices connected...
do you have a usb hub connected by chance or a reader for flash cards (SD, CF )

[cant]

no sure don't,only things that stays conected is a webcam,printer.I do have a 1gb internal memory card,I put in over a year ago.

[cant]

sorry yes a stick

[happyrock]

lets try disconnecting the printer...boot up and try to connect the mp3 player...if it works then try connecting the printer while the mp3 is still connected and working...try using the printer

[cant]

They both work when I do it that way.

[happyrock]

now try leaving the printer connected (the usb) but turn its power off ...the mp3 disconnected ...
boot up and plug in the mp3 player...does it work...if yes
use the safely remove icon in the system tray and remove the mp3...now power up the printer...test it...if it works OK plug in the mp3 player
