thank you guys for your help
The only place I found was the place where the company installed the 8 MG sample ram underneath the hard drive. Then I replaced the 8 Mg with my new 32 Mg(2 SIMMs 16 mg ) and when I turned it on I was big squeaky pitch sound , but the samples were still there and the sound was distorted . Do you think that the SIMMs I brought is damaged, or the place is not the right place?
