Laptop hangs at "Starting Windows" or getting "Error 0xC0000225"
Hi,
I have a Toshiba r700-181 (PT310E) work laptop. It is running Windows 7 x64 Enterprise.
It has one 4GB stick of ram which is PC3 10600. Windows works fine with this.
I have obtained a 4GB stick of ram which is PC3 12800. With just this one in, Windows works fine.
However, if I have BOTH sticks put in, the BIOS recognises that there is 8GB installed, but Windows fails to boot.
It gets stuck at the "Starting Windows" screen. If I restart it asks me if I want to start windows normally or to run the Windows repair. If I try that I get the message: "Error: 0xc0000225. The boot selection failed because a required device is inaccessible."
I tried using a Windows 7 System Restore disc but that doesnt work...
If I try either of the sticks in the laptop one at a time, then Windows 7 boots up fine.
Is this just down to the laptop not being compatible with the mixture of speeds? I thought that if they were mixed it would just use the lower speed by default?
So confused
