I was just doing some mild overclocking on my system: MSI K7N AthlonXP 2600 Tbred 333mhz FSB Generic PC3200 ram I had been running it at 333 locked. I was playing around this evening and bumped the RAM up to 400 FSB, but unfortunately, I think I forgot to ulock the 1:1 ratio when I saved. Now The machine is dead. The HDD LED stays on when it tries to boot, no bios, no video signal, no system beep. So what do we think blew? Could the CPU really have gone that quick with the FSB bumped up to 400 for just the second from the BIOS save to reboot? I shorted the CMOS battery, and that didn't help, right now I have the battery sitting out of the mobo. I'm looking for suggestions.
