I mounted the old HD (I want to keep all the data, programs etc) and old DVD and CD-ROM drives.
I changed the BIOS Set up to recognize the HD and CD-ROMs etc., set the boot devices etc.
The system is using on board video, audio, lan and USB etc.
The system boots up, goes through its memroy check, detects the drives, then I get an error message saying XP did not start properly with options to start in Safe mode, Safe mode with network,...., normal mode etc.
Whichever mode I choose, it suddenly gives a blank screen, and "RGB Input not detected" message (which I usually get when the monitor is turned on before the CPU boots up), then CPU reboots, ending with XP start options again.
The HD is ok, since it worked in the old system.
Did I miss any step in set up or anything?
Thanks for your help.
