i have a p-III 1.0 ghz pc. It was working fine. Now i changed my 128 mb sdram (HYNIX Made) by a new same ram. The system worked very well for some time nearly one month. Now it stopped working and beeps when i try to boot. I tried my ram on some systems it works well on some and doesnt work on some. What is wrong with it? Other RAm WORKS WELL ON MY SYSTEM. What should i do? Where the problem is?
