thanks
Many thanks and think you are right.
I did pay someone to do it but they cant find anything wrong with the hard ware.
The original location of software and OS was an 80gb hdd...this was copied I assume to the 250gb hdd
I assume this was straightforward enough.
however they have had a crack at it twice and found no fault...
so what am I to do...given the fault is intermittent.
When the system locks the light on the front of the tower stays on...only going off after it frees up.
I de fraged, scan disced etc tried disconnecting one of the 500 hdd after the other still cant nail it.
I could take it back but whats the point...unless I can demo it on site there ...but it might work for hours or like last night froze 3 times in an hour.
software wise I had explorer on but use firefox instead...ps7 cs3 nikon nx2...but I do pictures so software essential.
Many thanks for your help
