I bought my son a P4 Dell dimension 3000 I bought it completly basic just so he could go on the internet. What i did was hook it up to a D-link router which was also connected to my computer as well as my 360. now this is when things go wrong. The setup worked great for two months until my friend put media centre on my sons computer then it said that it couldnt connect to the internet so I put windows XP home back on his computer and when it booted up it was massive it was set to 640 x 480 screen resoulotion now this was just an eye sore but when I tried to reconnect my computer to my network it said cannot find hardware even though it is all connect perfectly. Could some people who clearly know more then I do help I would be thankfu if someone knows how to change the resoulotion Oh and i cant do it under display the bar wont move any further right and could someone explain to me whats up with the router and computer issue. Thanks for the help.
