I built myself a little computer reusing some of my LGA-775 stuff but I am having problems getting it to power on. I bought a 600w power supply (specs are below) which should be adequate for this setup, and it has run before, but now I can't get the computer to turn on. When I push the power button, the system powers up for a split second and then dies. If I push the button again... nothing. I can turn the switch on and off in the back all I get is that brief on state. The board has power indicated by a green LED, and the very first time i tried it the system ran fully powered. PSU Specs - Thermaltake TR2 600w I know Thermaltake units are hit or miss but it doesn't make any sense that it worked fine and now it doesn't. The power supply is brand new and it doesn't make any weird noises. I know there is plenty of power going through it because I can hear the normal faint buzzing sound. System Specs Intel Q6600 (stock speed) ASUS P5G41C-M mATX board Super Talent DDR3 4GB HD4870 512MB 500GB SATA-II HDD LiteOn DVD-Burner There are also 2 60mm fans and one 80mm fan plus the CPU cooler... Any help with this would be extremely appreciated, thanks!
