Hi, im not sure whether this question belongs in memory or OS, anyway, here goes. I have just bought some more RAM for my comp. I have an AMD K7 motherboard, 750 MHz Duron processor and currently run on 128 MB SDRAM PC133 on windows 98. The Ram I bought was 128 SDRAM, PC133, the same stuff. After I put the new RAM in and restart my computer I get the error message "Problem intializing CONFIGMG, Windows protection error, you need to restart your computer" When I restart windows it will only boot in safe mode. Just before it boots into windows there is a message at the bottom of the screen saying "HIMEN is testing extended memory......done." I dont know a great deal about computers but im guessing that this means the BIOS has recognised my extra memory, but its windows that is having a problem with it. I have also been through the windows memory troubleshooter and non of it works. My mainboard manual says that it will recognise extra memory up to 768 RAM, I have tried about everything I know, can anyone please help me?
