Hi I recently took out my pc which was mothballed for a few years and when i started it up it wouldn't boot up and kept beeping. I found out the battery had die so I put a new one in and obviously all the settings have gone. I'm trying to get it back to what it was but so far had no luck apart from that I can only use one stick of Corsair CMX512-3200C2PT and have another 3 sticks to install but it keeps beeping. I would be grateful if someone can tell me what BIOS settings I should use to get it back to normal. Do I need to update my BIOS and also the last time I updated it was about 5 years ago roughly. If you require any further details on the PC i'll try and provide it. Thanks if you can help.
