|"a intel dual core and motherboard i s a foxconn 45cmx-k model"|
Do you realize how many Intel dual core CPUs there are? Pentium D, Pentium dual core, Core 2 Duo, Celeron D, etc. At least the motherboard model will help sort things out. Here's the board specs:
Your board uses Intel 945GC chipset with Intel GMA 950 integrated graphics. The GMA 950 is NOT good for gaming so if that's what you're using, the only thing you can do to improve your gameplay is upgrade to a REAL video card.
