Welcome to TDF.
Can you tell us the manufacturer and model name of the PSU ??
^^ your's is a 250W PSU actually and is not suitable for running a GPU along with the quad core cpu you have - so get Corsair VS450 @ 2.1k and HD6770 @ 6k but if you have separate budget for the PSu get HD7770 gfx card @ 8k.
