Windows live mail causing display driver fail, system crashes

Help, Just put this system together, everything seems to work great, Supermicro server board with 2 3.2 gig dual core Xeon cpu, 8 gig ram NVIDA gforce 8400 gs 512 meg dual display. system gives me no trouble at all. regardless of how many tasks and windows open , but if i open windows live mail and try to send a reply or open and email with graphics screen goes black almost instantly, flickers than in a few seconds will give me BSOD saying attempt to reset the display driver and recover from a time out failed and dumps mem and reboots. have tried everything I can think of short of a video card. Have a new video card on the way, 64 bit ATI 2 gig PCI-X 1 will see if this fixes the problem. will post with results.
