Hi guys trying to fix my mums pc i gave her some time ago..been like a full rebuild and OS install. Problem im having is in task manager and cpuz its only showing as single core. Any ideas? For some wierd reason it wouldnt take its chipset drivers (nforce 780i FTW) and i had to hunt down a realtek all in one driver for ethernet. Kinda stumped what to do now as it must be a chipet driver issue right? When i download the supposed driver package from nvidia all it gives the option of installing is a storage driver..no other chipset stuff...
