hi, i have a dell dimension 4500 with 1gb Ram, a p4cpu, and a seagate 40gb barracuda hard drive. the ram was installed recently, and they are different brands of 512mb ddr. my computers programs kept on having problems and needed to close. after searching for viruses, and turning up none,i reformatted the computer using the dell cd from my dimension 2400. the other non-dell windows xp install cd wouldn’t work on this computer, i dont know why. anyways, after reformatting, the problem persisted, and the programs still closed. parts of AVG were even “experiencing problems”. what is wrong here? is my hard drive dying? and why do i get a blue screen from my ati catalyst drivers?
help?
