Have installed Network cards in two PC´s, which are using Win98SE. I am now experiencing shutdown problems. If the network cards are removed it cures the problem. On a second partition of my HDD I have installed WinXP which has no problems with or without the networks cards. Do I have to live with the fact that Microsoft cannot offer a resolution to this problem? Please note I have attended the MS Troubleshooting Course many times, have installed the so called fixes / patches, with no Success. I would installed WinXP in the other PC, but Microsoft isn´t giving away it´s software.
