I recently managed to salvage my old computer onto a windows 7 machine, all
is working and good!

However the experience has left me nervous of having no back up machine
sitting switched off but ready to go with windows 7 on it, and I thought it
would be handy to test run my backups to make sure they worked.

I thought I would resurrect my old machine, started off renewing the hard
drive but that didnt clear the problem (it is not going through the boot
sequence tries to start windows but dumps you into the repair screen and
then retries and keeps going in cycles) so I assumed it must be the
motherboard or processor, so I have just fitted a new one of those but it
still has exactly the same problem.

I should say the Hard drive (s) I have tried all work fine and boot up on
other machines

Can a dodgy power supply cause these sort of problems? if not what is it
likely to be?

At this stage I realize it would have been easier (and quicker) to just buy
a second working machine but I was lured into this course of action and am
now being stubborn and dont want to be beaten!

My fixation in windows 7 is just because its the last version that my Label
station printer software works on and changing to the new software would
involve rewriting thousands of Labels

Charlie, I doubt this is or ever was a hardware problem, sounds more like a
problem with the OS and drivers.
Did you use a backup of the OS from you other working machine to start the
old machine? That would never work and the more you change the hardware in
the old machine the problem gets worse.
A clean install of a proper copy of Windows 7 and all drivers would be the
way I would go but you would need the original key.
