Have an old faithful computer that was built for me 6 years ago. It will not boot up and apparently the chirrups it emits means the memory chip is "blown". On the side it says :- M.tec PC133 512MB. It has 16 chips on it but I don't know what to get as replacement because they all quote numbers of pins. Any suggestions gratefully recieved. Also found a site doing Kingston memory for around £15, any good?
