Help! How do I find my tabs when I changed computer

Hi all!
Can someone help me please. I jsut changed my pc because the motherboard stopped working. Harddrive is OK!
I was thinking of starting over now but I have a huge problem. I can’t find the Profile map on my old HD and I want to retrieve my old tabs, i.e start up tabs.
The strange thing is I can’t find a AppData folder under any user on my old HD. Can someone please help?
Many thanks in advance Mike
