hey when i boot my pc into xp it locks up with a black screen right after the windows startup sound. the only thing i have installed in the last few days was the latest nvidia drivers and battlefield 2142. and i have rebooted and shutdown many times since then. but now i have tried booting into xp dozens of times today with no avail. and i was just playing BF2142, shutdown cause i was running to town, get back and now no luck. i went into safe mode and disabled the nvidia tray, still same effect. what can i use to figure out what is crashing? is there an error log??
