Mouse Trouble

I have a problem with my PS2 mouse port in the back of my computer. All of a sudden, it stopped working. When I turn my computer on with the mouse plugged in, it does not boot up to windows but instead stays at a screen  with a blinking cursor. Is there any way I can fix this? Thanks.

Hello,

The PS2 does not allow mouse support. Please use included controller to play your video games such as Metal Gear, FFOnline and such. Purchase memory card as needed.
