I need immediate help! PLEASE!

I FINALLY got a new computer, it came with Vista (Didn't have it on my old computer..) and yeah.. Everythings fine, until it randomly started auto adjusting screen, then the monitor kept going into sleep mode.. Now that that's fixed, my little mouse cursor is uhh.. Completely gone. Can't see it. Can still click on things but yeah.. Took me nearly a freakin hour to get to gamespot forums.. I need help fixing my mouse cursor.. Any help is EXTREMELY HIGHLY SUPER DUPER FUNKALICIOUSLY APPRECIATED. Thank you. Now, to try n' get my mouse on the 'Submit' button.. -.-

(Five minutes fly by...)

Step 1: Uninstall Vista

Step 2: Install XP

Look at your mouse.
Recognize the brand it is.
Go to the manufacture's website.
Look for and download the latest driver from the site.
Install and update your Mouse driver.
Reboot your computer.

Was about to do what you said about the manufacturers website thing.. Too bad I went to open up a new tab, and guess what? Thats broken too. My f***ing luck! -_-

Now I need find the friggen Submit button again.. =_=

Woohoo! I fixed it.. Thanks for the tips. :)

Have a nice day/night, I'ma go get me some friggen ice-cream. :D
