My friends computer was working fine. She wanted to have a firewall, so i\ntold her to d/l zone alarm free. She did. Then after that, the mouse or\napplication of anything will freeze for 1-2 seconds then continue. She has\nbroadband, so it would be like you have dial up and you are waiting for the\npage to load when you spin the scroll wheel on the mouse.\n\nPrior to this she had her modem plugged into the front usb port, and printer\nin the back, she called and said the modem wouldnt work, i suggested just to\ntry putting the modem in the back usb and printer in the front... so that\ngot her modem back up. this was all in the same day.\n\nSo, what could be the halting/waiting problem. It has been fragmented, scan\ndisked, etc... could this be a usb problem? or a conflict of hardware? I am\nstumped. everything is operational and they are at 90% cpu perfomance.\n\nxp home, compaq box, i dont know what version.\n\n\nbrian s.
