ok ive purchased a wireless keyboard and mouse for my old windows 98 computer, and its been working fine since boxing day up untill two days ago when now windows 98 refuses to get past the windows 98 screen i have determined that it it the mouse by unplugging the mouse and plugging in an old mouse but i have no idea why if it was working 3 days ago and aint now! its really annoying. Can anyone help??? plz
