The problem is with windows Xp. I have 256MB RAM right now and xp runs pathetically slow. Is it due to avast! antivirus im using or due to small RAM ? avast checks every running process and new processes when they start. I think that makes my PC slow.
In case you suggest me to get more RAM, please tell me how much should i get, how much will it cost and what do i need to know before purchasing-- like good brands or something.
