Hello, I tried today to boot up my system with no ram installed I just wanted to check if it works. I have a ma785gm us2h motherboard amdx6 phenom 1075t I did not get any video display I would like to know if this is normal. I hear no beeps.
Yes, this is normal. Without RAM, you cannot get a display. Furthermore, if you don't have a motherboard speaker installed, you will not hear the associated beeps indicating that RAM was not present in the POST. You should get a motherboard speaker; it is an invaluable tool in diagnosing your computer.
Motherboard speakers are very inexpensive and can typically be found in computer hardware stores, such as Fry's or Microcenter. If there aren't any shops in your area, just do a google search for "motherboard speaker". You'll find a plethora of options.
