I am currently running windows XP (original MSP). I have just put together a new machine. Biostar NF61S MOBO amd x2 4400 CPU ATI X700 video card(512Mb) with 1 GB of kingston DDR2 ram (667). problem is when I am running any program with movement IE Games /screensavers I have pixelated transparent blocks on the screen. Not sure if I need more RAM or it a bad card. most other applications work fine including straight video... any thoughts ?
