Well here's the thing..
It now will only boot from the OS disc to the install/repair utility.
Have removed the two Ram cards (individually) removed the TV tuner card, only the graphics card now but need an adapter for the cable.
Now time for a stupid question.
When removing and refitting a CPU is it absolutely essential to apply a new layer of thermal paste between heatsink and CPU or can I just refit it with the residue of the original paste intact.
All the websites I see say to apply new paste, however these are aimed at building new systems or upgrading not refitting the same componants.
Just asking.
