I have a 5 year old system, but it was working fine until I started getting random reboots. Watching the temperature and voltages, and after installing "AI Suite 2" to watch, I get strange voltage low spikes, and AI Suite is giving me low voltage warnings again and again. I haven't installed anything lately and it has a clean startup (registry windows/run, etc). It just started doing this a few days ago, during a movie and some torrents. These voltage spikes weren't there when I configured this system. Please help! Maybe the supply is failing. Maybe the motherboard. IDK. Temps seem fine, watching CPUID HWM.. SB 70C, NB 68C, CPUTIN 48C but spiked on startup 122C which could be sensor bug, and AUXTIN 39C but spiked 110C sometime after startup. wth.
