I bought a PC100 RAM and put it in the appropriate slot. I got PC100 because the existing chip was already a PC100 one. When I start the PC it hangs while loading windows ! However, I can start the pc in safe mode. In the safe mode, the memory is properly shown as 256 MB RAM (I'm trying to upgrade from a 128MB to 256MB). Somehow, it just refuses to load windows in teh normal mode. Can anybody help ?
