Why whenever installing the DVD burner into the CPU, the RAM will be damaged? My friends and even myself have this sort of problem. I have two RAM in my CPU, one is 128MB and another is 512MB. After I have plugged in my new DVD burner into my CPU, I switch on my PC. Then my PC's screen shows some sort like the DOS and only then I notice that my 128MB RAM was damaged. Does it mean there's a need to unplugged all the RAM from the CPU before installing DVD burner? Or may be the damage of the RAM is due to electrostatic?
