I have XP SP2.
I had an 80Gb disk, but today installed a 750Gb.
I cloned using Acronis True Image then disconnected the old 80Gb drive.
Since then computer appears to work fine but reboots every 10 or 15 mins.
However.. 20 mins ago I converted the new disc to a 'dynamic disk' and so far I havent crashed!
Any ideas if this will be the fix and why this might have happened?
