Team Fortress 2 problem

[CannonFodder]

I have a problem... when I get killed, my screen flashes between two stillshots... the person who killed me and some other random picture.

Its annoying. Any ideas?

I'm running two 9800GTX+ cards....

turn off or on multicore?

Just started (as in, everything was fine before in this config) or was there a recent upgrade and this is the first time you played?

Recent upgrade. I tried both options (multicore on/off) and then updated my northbridge driver. Worked like a charm.
