Win 7 won't start with 4+ GB RAM
I have a computer that I built in 2007, with 2x1GB of 533MHz RAM, and I installed Windows 7 x64 RC Build 7100 on it a month or two ago. Last week I bought 2x2GB PC8500 RAM because I was long overdue for an upgrade.
I installed the new 4GB and removed the old slower 2GB, and booted up to find the Windows 7 boot screen, then everything went blank, including the keyboard LEDs, and the computer is completely unresponsive. I tried running it with one new 2GB stick and it ran fine, so i tested the other stick thinking i might have a dud, but again windows ran fine. I further tested the memory in separate bays so that it ran single channel instead of dual channel, but still nothing. The Bios always detects the memory amount correctly in setup and when booting the computer, but windows seems to hang with any setup with 4+ GB RAM. My board is good for 8GB RAM. I also reset the bios settings to default as was suggested to me, but still nothing.
I'm probably overlooking something, but for now I'm stumped. I'm pretty sure the x64 version should support 4GB. Any suggestions?
