Last night I installed windows 7 x86. i clicked on my computer it said 2gz ram then i installed some drivers and clicked on my computer and it had 4gz ram. it had Aero and when i installed battlefield 2142 and played it, it felt like 4gz. today i installed black and white and installed the recommended updates from windows and black and white 2 i click on my computer and it says i have 2gz... and areo effects etc is gone... what's going on? I need to have 4gz. I have some questions is x86 = 32 bit? I read on the web that 32 bit can't see 4gz of ram is that a rumour or true? if so how come i had 4gz before. did the updates stop windows 7 from ustilising the other 2 gz of ram? does reinstalling/installing mobo driver or gfx card driver affect anything?
