probably yes, but check your Page File size too, it should be 1.5 times bigger than the amount of ram on the system.
page size? what do you mean?
Page file size. Basically when you pc runs out of ram, uses the hard disk drive to simulate ram (random acess memory), and thats bad, because it is going to run slow. Your Page file size should be 1.5 or 2 times your ram size, so if yiu got 256mb your PF would be 384 or 512, at 512 it should be 768 or 1 gig.
