So the power will rise enough, when installing the software to cause a blue screen? It is only installing the OS. Nothing stressfull about that surely? I don't know.
Worth trying a dif PSU then? Didn't think the PSU would ramp up while installing software.
It was the CD guys. He used a dif one supplied by his local PC shop, with SP3 on it and it worked fine!!
