I'm currently trying to upgrade my computer. I have a MSI K9VGM Motherboard, http://www.msicomputer.com/product/p_spec.asp?model=K9VGM-V&class=mb I tried to intall 2 gigs of ram but one of the dimms seems to be defective. I tried different memory sticks and all I get when I try to turn on the computer is a series of long beeps. I've had the motherboard for over a year now so returning it is out of the question. I'm wondering if anyone has any ideas as to how to fix this problem. I can buy a whole new motherboard but I don't understand why a dimm that hasn't been used before is defective.
