Game Freeze?

[Guest]

Ohk iv read like a gazillion threads , But every time i start a game it runs smoothly and then freezes and then unfreezes for like half a second and then freezes again an the computer locks up .
I read about the realtek HD Drivers having conflict with my Asus 8600gts so i uninstalled it and put in a new sound card - Sound BLASTER!Live - installed those drivers loaded the game and frozen again.
Ive checked my psu 300W support 12v and stuff got the 6 - pin pcie cable .
Although my motherboard has an ATI chipset could that be the problem?
My specs are :

Processor :Intel Celeron D 3.06 Ghz

Motherboard :RC410-M

HP/Compaq motherboard name: Asterope2-GL8E

512 Mb DDR2 - 400 mhz

80gb 7200 rpm hard drive

Graphics Card: Asus 8600gts - 675mhz core clock -
and Intergrated Graphcis

I have the latest Drivers for My graphcis card Please Comment Im 100% confused .

give your system more ram 512 is just not enough,also your swapfile is affecting everything as a result of only having 512 ram,,NOW THEN ,,consider putting in motion a plan to replace your system keep the hdd and the 8600 as temp starting points,replace the mobo the cpu and the ram,you can do the rest as you want to...

Adding memory to your machine should be the first thing you do to improve gameplay and system response.
512mb is simply not enough
