So i am using a real old pc with GA-945GCM S2L mobo i have 2gb of ram installed in. Currently my ram is placed in second slot when i swapped it to first slot my pc started beeping. It is a continuous short beep so its definitely ram issue putting back to slot 2 it works,however i have also notices sometime it works on 1st slot. How can i get this thing fixed since i want to upgrade to 4gb of ddr2 ram.
