I have some further info on my problem which might help? I have noticed that if I unplug the Cat 5 cable from the hub that serves the PC that freezes, it stops doing it, but if I leave that plugged in and remove the Cat 5 cable that from the hub that serves the other PC, which works okay, the troublesome PC still freezes. It would seem that just having the hub powered up and the ethernet card connected to it upsets the PC. I have an ethernet port on the motherboard, and a PCI ethernet card in the PC, and it happens with both of them. Has anyone any idea what conditions could be causing my problem.

Everything has gone quite well until now. I recently installed a home network using a 5 port hub, and the main PC (just described) started to freeze completely, nothing except a reset would do anything. There was no pattern to it, sometimes it would happen quickly other times it would not. I removed the network and eventually re-installed Windows XP all for nothing for now it freezes even more regularly. Some programmes seem to be more prone to the freezes than others. Just for good measure now and again the system will just close down (black screen) for no reason. The other PC on my network, of similar spec has performed faultlessly. Can anyone please help me.
