Have a custom built machine that I made about a year ago. Intel 2.4 P4 and Asus P4S8X mobo. Lightning hit near our apartment complex today; I have the machine on a top-of-the-line power strip which is plugged into an APC BK650MC 650vA battery backup.. Even though I have it on the backup, the machine powered down. I turned it back on, and it booted straight to BIOS and says "Machine started in safe mode due to invalid CPU speed detected during bootup. Please reverify CPU and machine settings and reboot." Considering I never went in and set anything, and I'm running the standard 2.4 (and not overclocking), wtf? Obviously I probably need to replace something; considering it boot to BIOS, is it just the CPU that I need to look at replacing? Or is this not the problem at all? Help.. I need that machine..
