I reformatted (NTFS) and installed fresh copy of win2k pro on cpq presario 5000 (PIII 500 megahertz). Service pack 4, all MS updates, downloaded Intel 82810 chipset (video) drivers latest version yet unit locks when I do various browsing tasks. Any ideas? I've seen some HP's that simply do not support win2k. hope that is not the case here.
