I have just finished building my second computer (the first ran beautifully for 7 years - only had to replace the video card after 5 years), and it doesn't boot up. No video signal what so ever. My question is this: is it possible that the power supply isn't strong enough for it to boot? I'm using an Antec True Power 430 20 pin from the original machine I built 7 years ago.
MoBo: Gigabyte GA-EP45-UD3P
CPU: Intel Core 2 Duo 3.0Ghz
RAM: 2x2 gigs G-Skill ddr2-1000 PC2-8000
Video: BFG Nvidia GeForce 9800 GT
I have set it up so only the video card, 2 sticks of RAM and CPU are connected (no hard drives). The fans turn, and the boot lights on the MoBo turn on, but the CPU fan only budges for an instant when I turn it on, and then stops. The CPU fan also budges an instant when I finally give up and turn the system off, so obviously it gets power, at least for an instant when I turn it on and off. Could it be not enough juice out of the power supply?
Any ideas? I'll go through the bare-bones trouble-shooting if necessary, but if my power supply isn't enough, I may as well just replace it before going through the trouble...
