My PC at home for some unknown reason now boots up without mouse drivers and I'm not sure how to fix it! (Typing this at work as I can get on).

Can you move the cursor without a mouse using the keyboard somehow?

yes you can use the keyboard. Can't remember the keys offhand, but I am sure someone will on here.

What OS are you running?

If you mouse worked previously and then suddenly stopped working, it is probably a duff mouse. Have you tried a different mouse?

Windows 98 - space to scroll, arrow keys to move the cursor, enter to left click, escape to cancel/exit, alt+tab to switch between open applications... erm.. that's all i can remember at the moment!!! Hope it's useful!

Use your 'windows' key to access the 'start' menu or Alt-S. Holding the Alt key down and the underlined letter on most windows applications menus will let you access the menu options.

Unplug it from the mains and hit it hatrd with an axe. Go one, you know you want to!!
