You will not beleive this - I do not know what causes it and cannot get it to behave any different (played with CMOS settings etc) but my PC once windows starts wants to use the external video port and not the internal one. It cannot be convinced that there is no external device so every time I boot...

Sir

Did you resolve you problem - I have exactly the same and cannot figure it out

Have re-loaded the drivers all to no avail
