[SOLVED] Windows 10 freezes at lock screen with more RAM

[time-flight]

So I recently installed Windows 10 64-bit on an old 64-bit compatible PC. During the installation, I made sure to have just one DIMM in the computer because that’s apparently a good way to avoid BSODs and other errors. The installation seemed to go well and was very fast.

At the moment I have 2 pairs of DIMMS, with two of the sticks being 2gb and the other two being 1gb, making a total of 6gb of RAM. All the DIMMS are in what I would describe as ‘like new’ condition.

When I attempt to boot up Windows with the one 2gb DIMM installed, it boots up fine. However, if I install the other matching 2gb DIMM and/or any of the 1gb DIMMS with the first 2gb DIMM, Windows freezes at the lock screen or becomes very slow to the point that it’s impossible to sign in. When I press a key or click the mouse to get the sign-in screen to appear, it freezes and then gives up and goes back to the lock screen.

Not sure if this is a problem with the video card or CPU or something else, but it seems like a weird thing to happen after installing more RAM sticks.

• Firstly, are the 2x2GB sticks from the same pack? Mixed modules are not guaranteed compatibility.
• Have you reset CMOS after installing just the 2GB modules?
• Only having 1 DIMM installed during installation wouldn't really make a difference. A BSOD will occur when potential corruption occurs, having more than one module wouldn't make much difference unless the RAM/slot was faulty. At least - I've not experienced anything otherwise.
• Have you changed anything else?
• Are all drivers up to date? (Not using a driver updater app).

Thanks for the help, resetting the CMOS after installing the 2GB modules and then enabling the 'memory remap feature' in the BIOS fixed the problem.
