winxp

I had installed winxp for a client…worked fine for three days then the network just disappeared and norton is permanently disable and every time you restart the cpu there is this message….”your compiuter has rcovered from a serious erro” or sometning like that.

My network connections are not visible and i cannt run the network connection setup wizard.

I thought it was a virous but after three anti-virus programmes…norton 2003, avg 6, vexira…nothing .
