Loft condensation and insulation

[YCDCN]

I noticed we have moisture in one corner of the bedroom, then i remembered seeing a lot of condensation in the loft.
My thought is that the loft insulation needs replacing anyway as it is thin and old.
If i insulate the floor joists with the relevant amout of "stuff" and use a system like Loftzones Storefloor that would help some of the problem.
Then, if i use the foam board insulation for insulating the roof and maybe even plasterboard it.

I will also have a couple of Servers and other bits running in the loft (yes geek alert) so there will be a bit of weight and heat from them.

Would be interested in peoples thoughts.

Not sure what your question is?

Your problem is not enough ventilation from the loft to outside and damp air leading through the ceiling into the loft. In that situation more insulation will make it worse, so don't change that first.
