Please help. I recently installed an additional 512Mb of ram to my pc. I had 2 x 512Mb installed previously. in slots 1 & 2 and installed the new ram in slot 3. The pc still only says that there is 1024 of ram installed, although when i run pc wizzard it shows all 3 sicks of ram and gives the details of the ram as well. i have tried fitting a single ram in each of the slots 1, 2 & 3 and re-booted each time and carried this out on all sticks, prooving the ram and slots are ok. I then tried a combination of 2 sticks, with a stick in slot 1 & 2 the systems shows 1024Mb, with a stick in slot 1 & 3 the system shows 1024Mb but with a stick in slot 2 & 3 the system shows 512Mb.
The spec on the motherboard says that it can handle up to 3Gb of ram. I am hoping that this is a case of updating software / drivers etc. to allow the system to recognize all of the ram, but not sure how to proceed, and would appriciate any help you can offer.
The system details are as follows:
