What hardware can cause crashes?

[ytriffy]

Hi, list.
I recently send some debug data to hackers about crashes on my system.
But it seems that no one knows how to help me.
So I rely on you to help me determine which hardware can cause  frequent 
crashes(page faults mostly).
My system specs:  Athlon(tm) 64 Processor 3200+, MB: ECS (nforce4) A939 
,  geforce 6600gt 128mb,
two memory modules  kingstone and kingmax both 512mb, two hdd drives 
Samsung and WD both 250GB, Realtek chipset NIC,
Cirrus logic cs4281 audio card.

Any suggestions are appreciated.
