On boot up I can get into BIOS no prob - set up boot sequence no prob - BIOS recognises CPU, Ram, HD and DVD drives - save and boot and I get a NO INPUT SIGNAL message and system reboots and goes through whole thing again
Do you mean you are trying to boot from a hard drive that had the operating system already installed? That is probably your problem.
Hi - yes I am using an HD that has XP already on - I have done this before and never suffered this sort of problem - unsure why this would cause a problem? I am using the on board graphics - but have tried this with a Radeon X1950 Super pro ATI card and still got same - have used ram off another computer and still same - any ideas? and yes it is an on screen message
Proximon hit the nail on the head. You can rarely take the HD out of one computer and move it to another and expect it to work. The old HD has registry entries and drivers for the hardware in the system it came from. Even if you manage to cobble it together and get it to work, the performance won't be nearly what it would be from a fresh install. Do the right thing and perform a fresh install if you want a stable, fast system.
