Crazy worked fine one night and the next won't post, boot or anything. Troubleshooting section in manual claims the system is not recognizing the memory. Blinking lights on the Caps Lock, Scroll Lock and solid light on the Num Lock. I reseated both sets of memory, and replaced with memory from a working laptop and still nothing. I removed the HD and hooked up to a Desktop PC and it is working and all files are visible. Don't even get a flicker on the screen and when the keyboard was removed to re-seat that memory the fan isn't visually energized either. Any Ideas?
