hi all 
having major problems with my computer of late i bought both parts from overclockers but im not sure which part or both is causing these problems
what it is ive been playing a lot of new games latly aswell as bf2 which i always play
im getting major artefacts in all games of late but im not sure what it is that could be causing it.
i bought these from overclockers
gainward biss golden sample 7900 gs 256 mbs card.
asrock dual sata motherboard.
dual core 4400 cpu.
im getting like weird artefacts in all games not as much as what i do with the new games though.
in silent hunter 4 for example im getting green flashes on screen aswell as loads of lines all over my screen so the games become vertually unplayabl;e
ive tryed old and new drivers-still the same
im stuck on what it is thats causing these artifacts
could it be my ram as i have 1.5 gig of ram but there different models?
could they be cauing this?
is there a tool i can get that will tell me whats cauing these problems?
i really hope some1 can help me here as ive obnly had the equipment for like 6-7 months and really for the money ive paid out i should be getting 1-2 years worth from the stuff i bought maybe more
please help some1 thx
