I have had an sn25p running great for about two months, then suddenly it won't boot. I get no power - no fans, no lights, no beeps, no video, nothing. I tried another video card but that didn't help, and of course I've tried resetting the cmos but that didn't help either. I guess the psu went bad. Is there some way to test the psu, or try a generic psu externally? The motherboard doesn't have the regular ATX psu connector so I don't know how to check it. Anyone have ideas? My system consists of the following: - Shuttle sn25p - 2 GB RAM - Leadtek Geforce 6600GT - Hitachi 160MB HDD - Lite-on DVD burner - AMD64 3200+ (venice) I think the PSU (350W) should handle this fine. I'm not overclocking and was actually throttling the CPU down to 1GHz when it wasn't busy. Any ideas as to how to test the system or what the problem may be are appreciated! Thanks! rich
