( Redirect) upgraded Dell latitude D630 to 64 bit

Can anyone help please, my daughter give me a Dell latitude D630. Unfortunately while closing down the mains lead fell out this caused the computer to boot up to the ‘your computer failed to close down etc’. in an endless loop. As there was no backup disc or restore point I had an old copy of xp pro 64 which I loaded over the original xp32, I can’t now access the wireless internet. I have the following driver probs. Display adaptor (Standard VGA graphics Adapter) Modem Dev. Ven = HDAUDIO\FUNC_02&ven 14F1&DEV_2C06 SM BUS CON PCI\VEN_8086&dev_263e Video Controller PCI\VEN_8086&dev_2A03 Network Controller PCI\Ven 14e4&dev_4311 ETHERNET Con. PCI\VEN_14e4&Dev_ I have downloaded lots of drivers, hunted for 64 bit versions and find myself completely overwhelmed by the choices so if anyone can point me in right direction or even supply the required drivers with instructions I would be very grateful Thank you DaveC
