Hi, i am having a problem with my desktop computer. It was been built peice by peice so no brands or models. i was playing a game earlier today and i either hit the power button with my knee or it just restarted on its own... well when it restarted it wont let me get on the internet. It says limited or no connectivity... i have a wireless router that is brand new. I have another computer that is hooked to this router and it works fine, i have a PS3 that is wirelessly connected fine. I have used command prompt to reset my winsock and ip. I also tried to hook the computer strait from the modem bypassing the router but to no luck. I opend the device manager and there were no red 'X' or yellow "?" for my network card... i dont know what else to do... anything help would make me extremely happy... thank you.
