My laptop makes me so angry >:[

*** Hardware Malfunction
Call your hardware vendor for support
NMI: Parity Check / Memory Parity error
*** the system has halted ***

Can anyone tell me
a) what this means
b) what can be done about it
and c) how to relax when it happens so that I don't kick it's bluescreening ass out onto the streets.

It's been doing this for a long time, the laptop's a couple of years old, and it's driving me mental. Blah.
