this problem just happened today while i was USING the computer...i use a optical mouse ( those that is directed by a beam of laser instead of a roller ball ) ...while i was working...my mouse stopped suddenly...the light (laser) went off...after a sec later it lit up again...something it would just stopped and wouldnt lit back up...the light is flickering...and the arrow on my monitor screen wouldnt move

so can anyone help me or suggest any idea? is it too old...i had it for about 2 years... :-/ :-/
maybe the batteries need replacing......aslo do a scan for trojans BUGS etc.....um my mouse doesnt have any SCREWS so i dont think i can take the mouse apart. beside...why would it need battteries when it's attached to the computer
i have an old mouse from my old computer, but the plug doesnt match this computer...so i cant tell if it's my computer or the mouse itself...oops thought is was wireless

what o/s is this.......update drivers for it....or CLEAN the surface it runs on?>http://support.microsoft.com/default.aspx?scid=kb;en-us;321122mice USUALLY only last a year.. Well, when I use them anyway.

Perhaps the cable has been damaged. Does it have a tight connection to the PS/2 or USB port?
