Fantastic

So I upgrade the BIOS, and I boot fine into Windows. I think everything is working. I then try playing the game again. 2 minutes and I get another crash.

But then I reboot and I see that the computer thinks I have a slower processor (a 1500+). So I go into the BIOS and change what I thought was the correct setting (to what I thought it was before the reboot), and I try to save and restart. Well, the screen goes black and nothing happens. The monitor LED turns from green to orange, and the computer sits there. No reboot, no beep codes, no nothing. I have to flip the switch on the PSU to restart. I go back into the BIOS and the change I made is still there, so I'm able to save my settings, just not reboot following them. But now I can't get beyond the POST because it says my CPU speed is set incorrectly. "Duh!" I think. But nothing I change seems to affect the speed.

I don't know much about the chipset values in the BIOS, so I don't really know what I'm doing.

Please help!!
