USB mouse doesnt work help!!!!!

[alexgreenday]

I recently got a new case with a power supply of 420 w instead of 250. It was working fine for a day until today the USB laser mouse stoped working. I tried numerous different mouses and they didnt work. WHen i put the mouse in an error message comes up that says USB device not recognized. I installed my USB drivers but it still doesnt work. What can i do to fix this or what do u think the problem is?
thanks very much

What version of Windows?

Alex:

Do you get the message before or after you see the starting windows splash screen?

Try unplugging the mouse, waiting a few seconds, then plugging it back in.  

Try checking the BIOS settings to see that the USB ports are still enabled.  There may even be a page in the BIOS setup to choose whether the system uses a PS/2 or a USB mouse.

Blessings to you,
Doc

I have a USB adapter but the mouse still doesnt work. When i use the adapter my mouse lights up but then it doesnt work. What else can i possibly do to fix this problem?!?!

Remove the mouse from the device manager, shut down and plug the mouse into the ps2 port (green) & re-boot.
Let windows detect the mouse & install the drivers.

One of the USB devices attached to this computer has malfunctioned, and windows cannot regonize it.  I tried reinstalling the drivers but it didnt work. PLEASE HELP!!!

Does anything apart from a mouse work in the same usb.

Have you tried your mouse on another usb port.

I tried my Ipod and it works for that but my mouse still doesnt. Now when i plug in my mouse it says it found new ardware but when i click it for more information it says there is no drivers for it but there is.??

Remove the mouse from the device manager, shut down and plug the mouse into the ps2 port (green) & re-boot.
Let windows detect the mouse & install the drivers.

Why would you want to plug into a usb port when there is a ps2 port that was designed for a mouse?

Try a system restore and if this doesnt work like FED said just put it in the ps2.
