The secretary in my office complained her machine often locked up after typing upper case i. The machine has to be hard reset, loosing what she was working on. It happened more in the morning but not every day. So after updating the PC-cillin & doing a full scan & finding nothing I guessed it might be hardware, so I changed bits until evenutally I changed the whole PC!! I was in the room loading the last of her files & another girl came in & said the same thing had just happened on HER laptop! Help!One PC is a generic PC running 98, PC-cillin & office 2000, the other is a Dell laptop running 98 & office 2000. Any ideas??
