Thanks for the replies guys:
...or you may have an on-board VGA adaptor that needs disabling with a jumper change. Can't tell you for sure I cannot find a reference to the motherboard model you're quoting (not on Google as least).
Sounds interesting - there is an onboard VGA adaptor, so this could be the problem. Don't know how I would change the jumper settings though? Could I just remove my video card, is the onboard one better than what I have? (see below for spec)

The OS is Windows XP - once the PC boots up hopefully the OS should fire up as on my previous system as I have taken the old hard drive out.
Once I get this sorted I will probably upgrade the HD.
