i have tried to install vista beta 1 (5112) and beta 2 (5270) but it runs verrrrrrrrry slow to the point that it doesnt work. i dont see why because i have a good enough pc. it runs fine in a virtual machine but wont install directlly from the dvd drive. i really need some help. my specs if it matters ram 1 gig hdd space 160 gig processor intel 3.0 ghz pentium 4 video card ati radeon mobility 9000
