I'm getting BlueScreens about every five days for more than three months. Here's an example:

A problem has been detected and Windows has been shut down to prevent damage
to your computer.

The problem seems to be caused by the following file: ntoskrnl.exe

CRITICAL_OBJECT_TERMINATION

If this is the first time you've seen this stop error screen,
restart your computer. If this screen appears again, follow
these steps:

Check to make sure any new hardware or software is properly installed.
If this is a new installation, ask your hardware or software manufacturer
for any Windows updates you might need.

If problems continue, disable or remove any newly installed hardware
or software. Disable BIOS memory options such as caching or shadowing.
If you need to use safe mode to remove or disable components, restart
your computer, press F8 to select Advanced Startup Options, and then
select Safe Mode.

Technical Information:

*** STOP: 0x000000f4 (0x0000000000000003, 0xfffffa80065f2b30, 0xfffffa80065f2e10, 
0xfffff80002f9bf40)

*** ntoskrnl.exe - Address 0xfffff80002c98d00 base at 0xfffff80002c19000 DateStamp 
0x4d9fdd5b

It's has always been the same BlueScreen message showing CRITICAL_OBJECT_TERMINATION, 0x000000f4, and ntoskrnl.exe. Of course the addresses change.

My computer is a ThinkPad T400 (about 2 years old) with a SSD in it. I'm also running Windows 7 Professional 64 bit. When I bought my computer, it had a 250GByte SeaGate HDD in it, which I replaced by a 500GByte HDD by Western Digital. Last september I bought a Corsair F120 SSD and replaced the HDD by this SSD. Then I bought a LEICKE HDD adapter for the UltraBay II where I plugged in my 500GByte HDD. This configuration ran about half a year without any errors. After re-installing Windows this spring, I am getting regular BlueScreens. Sometimes my system runs for about 2 weeks without a BSOD, sometimes I get several BlueScreens a day.

The only thing that I noticed is, that I'm always running Google Chrome when it happens.

Is there anyone who has made his/her own bad experiences whith some of my components or is there anybody who can tell me if it would be helpful to send my notebook to Lenovo?

Thank you very much for your help on my issue!
