You need more proof? :) Best get yourself to Fry's, CompUSA, or some other retailer and buy some memory. :) One test is to buy new memory with a return policy. If the system works fine with the new memory, you know the old is bad. If the new memory doesn't work, take it back in for your refund. > Thanks much, > Nick -- John Baldwin -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
