my win 98 pc hangs, usually when logging onto the internet, sometimes when printing. i installed sys mon, it showed very hight kernel usage when opening the internet. i had 64 mb RAM, so installed another 64, now have 128 mb but sys mon still shows excessive kernel usage. so i turned off all start up programs using msconfig, still no help. i then completely reinstalled windows, including fdisk and format of hd. pc is running minimum applications, 400mhz pIII processor, 128 mb RAM, but still hangs and runs slow alot. do i have a hardware problem? any suggestions?
