I've been having problems with a blue-screening Laptop (BCCode 124), and I've been trying to track down whats causing it. (It bluescreened randomly after 5-30 minutes of running in win7). It worked in safe mode. I tried reinstalling Windows, which didn't work, so I tried to install various Linux systems which also didn't work.

The only thing working right now is the parted magic version of the ultimate boot cd.(Its a repair linux distro that runs live from ram)

I had the idea to run a bunch of stability tests to try and isolate the faulty component(s), and I wanted some input on my results.

I did different cpu stresstests for different times. No problem (temerature ~60°C sometimes peaks at 65)

I ran memtest with no errors many times.

I also did a GPU check wich is included in the ultimate boot cd - parted magic distro - no problem.

I also checked the hard drive with different tools included in parted magic - no problem there too.

Every linux system I try to install crashes when I try to install it. (It either freezes with no error (rarely happens) or I get something like this shortly after I tell it to install (tried about 20 different distros):

Trying to isntall windows 7 just gives a generic "there was a problem" / "an error has occured" screen with no further information.


The laptop is a Lenovo B570. Here are the detailed system specs (the ram is a 4GB kingston now)

Can you help me to track down the cause?
