I just completed my new build... (New components) Maximus Formula Intel Quad Q6600 G0 4 GB of Corsair XMS2 PC8500C5 RAM (2 sets of Twin2X2048-8500C5) Corsair 550VX PSU EVGA 8800 GT 650 MHz Tuniq Tower 120 (Existing Components) Seagate 500 GB SATA HD DVD Burner CD-Rom Floppy Drive Case- Tsunami Dream 3000 At any rate, I waited for 1.5 weeks for my video card and installed it last night. When I turned on the power supply, the the power, reset, and CLCMOS buttons light up on the motherboard, as well as the top of the sound card. When pressed the power button on the front of the case, the leds and other things light up on the motherboard for about 1 second and turn off. The case fans spin for about 1 second as well and shut off. The LCD Poster displayed CPU INIT, but it does this even before I push the power button on the front of the case. Last night I... Checked the 8-pin and 24-pin power connectors. Checked the connectors on the system control header. Then I got tired and depressed! Here is what I am thinking... 1. I will take out all but one of the RAM sticks and try to boot. 2. I will try to boot with only video card, monitor, cpu, heatsink, and fan. 3 Could be a PSU issue? From Corsair, I hope not. 4. Will try to clear CMOS and take out the battery and all that stuff (read a bit on the forums of other sites and have some instructions to follow) 5. I may have a short somewhere. 6. Last, will reseat the CPU. Could the heatsink be screwed down to tight? Any other ideas, suggestions, thoughts? Thanks guys. I will post back with results.
