I have a Thinkpad T410i notebook with Windows 7 64-bit installed.
It has 2x 2GB a RAM in it. I want to upgrade it to 2x 4GB.
I got the RAM installed, in the BIOS its okay but Windows won't start. The loading screen freezes, in safemode it stuck at classpnp.sys, I tried renameing it to classpnp.old, after that its stuck at disk.sys.
Windows recovery doesn't load.
I loaded it with a Ubuntu live USB stick and that works.
The ram is Kingston
4GB Module - DDR3L 1600MHz
Part Number: KVR16LS11/4
Specs: DDR3L , 1600MHz , Non-ECC , CL11 , 1.35V , Unbuffered, SODIMM
Is this not a good memory for Thinkpad T410i?

Welcome to the forum!
If it works with Ubuntu is definitevely a Windows issue. Did you try to start in safe mode? Press F8 immediately after the ThinkPad logo appears when booting.

You can try to install MemTest 86 (http://www.memtest.org) to a USB Drive and let it run for several passes (better overnight) to make sure that the RAM is not defective.
(Actually the RAM you bought is a Kingston Value RAM line (identifiable by the KVRxxx code), this type of RAM sometimes don't work well with ThinkPads, but mostly it's hit or miss. If it runs with Ubuntu it should also run with Windows)
Maybe some WinGuru can share more light here about that classpnp file...? :-(
