Yep, like the title says im missing Ram or i might not know anthing about it. When i got this laptop it came with 1Gig of Ram. But it's only registering 502megs of it now. I think this may have caused my computer to slow down drastically, since i was told by other people that im crazy for running Windows Vista with only 502Megs of Ram. I have just recently Reformatted (my drivers failed and it took a few tries to get windows to actually load completely) and done a few steps to remove some harmful things from my computer (i found a trojan which is removed now).
