My wife turned my comp off after I went to bed last night and when I went to restart today it acts like an old christmas tree. the power flashes on and off fairly rapidly, until I kill it with the power switch on the power supply? Does this mean the power supply went south? I built this amd64 system just this spring. I have a CoolMaster450 watt PS,amd 3000+ cpu, on a Gigibyte GA-K8NS Ultra 939 MB, nvidia gforce 6600gt Anybody seen a comp act like this before?
