I have a Gateway FX6860-UR10P. Core i7 3770. It came with 12GB DDR3 RAM (three 4GB sticks) (upgradeable to 16GB). The motherboard is an Acer Ipisb-vr Rev1.01.
I started having problems with the computer about a year ago: random graphics card glitches and freezing, it would only recognize 8GB RAM. Recently, the computer just froze repeatedly on a Windows startup, repair, and/or fresh install. I could wipe the drive and load Linux Mint just fine.
Here are the things I did that didn't help:
1) replaced the motherboard with a new one (the exact one it came with)
1) replaced graphics card
2) moved RAM to different slots
3) fresh Windows install
4) wiped the hard drive and reallocated the sectors
Finally, I replaced the hard drive and that fixed my freezing issue. But now I still have the RAM issue. It will only see 8GB not matter what slot combinations I use. If I use more than 8GB, I get 4 beeps. I have tried the RAM sticks in different slots so I know all three sticks are good. They just won't work all together.
It doesn't make sense that it's the motherboard since it's a new board causing the same issue. It isn't bad RAM. I've tested it in all slot configurations with no success. New graphics card. New hard drive.
It used to recognize 12GB with no problems. Now, it will only see 8GB despite everything I mentioned. What could be the problem? I am running out of ideas.
