Just to update  in case anyone else has similar issue in the future..Thanks Styloid for the suggestion to replace the cmos battery...we had done this previously HOWEVER..I noted that the original battery and the replacement had different digits ..one was CR2025.  the other was CR2032...as soon as I replaced like for like we were able to turn on without 7 beeps..at this stage it won`t initialise past the black oblong in the display but I am fairly confident that is a HDD issue...so I will advise once done..Also many thanks to DHook for his valued suggestions and assistance..most appreciated..
