Whenever I call someone or I get called, my computer crashes with a BSOD of Machine Check Exception. It usually crashes just after I am connected to my peer, or after sometime talking, usually 5 10 minutes max. I don't have any minidumps somehow, I only got this : Faulting application svchost.exe, version 18.104.22.168, faulting module svchost.exe, version 22.214.171.124, fault address 0x00001432. Which is stamped 10.56 PM, and I was back to MSN from my crash on 10.53 PM according to my chat logs. Thanks.
