[BSOD] Bugcheck 101; what is it?

[cypherinfo]

- Windows 7 x64 bit;
- the original installed OS on the system: windows 7 professional 64 bit;
- full retail version;
- the age of system (hardware) one year;
- the age of OS installation: seven months after last installation.

This is my first time I get the bugcheck 101; I wonder why.

Thank you.

It's a hardware related error message.
It can sometimes be caused by a overclock that has become unstable.

I see it is in some way related to a PCI Express interface; I wonder if you may determine what hardware device is installed there if any; I have a notebook, no overclock and no hardware device installed.

Thank you.

Just so you are clear on one thing, the laptop itself, is hardware.
I'm sorry to hear this is coming from a laptop it could mean the device is at the end of it's life.
There are far more things you can do and parts you can replace in a desktop.

There is a slight chance that you did not properly secure the heatsink when cleaning the fan, and overheating could cause a problem like this.
I'm sorry to say short of the steps at the link there isn't a lot of help we can offer via the internet for this kind of thing.
