windows update help

[dalex]

a relative bought a new tower with windows media centre pre-installed from an auction site and it worked fine until it updated to sp2 from automatic downloads , now when ever he goes to microsoft to download and presses express or custom instal,to download anything at all, the pc locks up, its a genuine activated copy of media centre
help please its very frustrating
