Long story short.... System was being run at 145 fsb with a p3700 on a be6-2 rev1. Without putting back the bios to default, a p3850 that wsa working properly was inserted and would not power up, only a black screen. After placing back in the p3 700 and placing the bios back to default, the 850 still will not power up. Is it possible to burn out a cpu by running it at such a high fsb even if for a second? I know the 850 was working before as I would run it at 115 fsb all day long, but at 120 it would not boot. So could 145 destroy it that quickly? Thanks for any replies in advance.

it's possible but not likely....I'd guess the mobo is gone.
have you tried to unplug everything but the vid card?
Have you tried booting with the insert key depressed? It will force the MB to try to boot at default settings and will generally get you into bios if the chip isn't dead.

Completely clear the bios and unplug everything - i mean everything, remove processor, etc.
Leave for about 1 hour and make sure the clear cmos is selected.
Power up with just the board plugged in and nothing else, the plug the ram in, then the CPU and heatsink, then the video card with just a keyboard and video lead plugged in.
If this works continue installing the rest of the hardware and set up the system as required.
Let us know if this works ok.

It's probably understood...but power down the board between parts installs. :)
