Hey peoples... Hope this is the right sort of place to ask. As the topic title makes reasonably obvious, I'm trying to put together a PC. Well, no, that's misleading. The thing is, for all extensive purposes, put together. There's a bit of a snag, though... It doesn't work. At all. Here's what I've got going... CPU: AMD Athlon 64 3800+ Motherboard: Asus A8N-SLI Deluxe Socket 939 PSU: Antec 500W ATX12V RAM: 2GB Patriot DDR400 PC3200 Video card: ATI Radeon X1800XL (Asus) Hard drive: Hitachi Deskstar 7K80 (x2) And I've also got an Asus CD-RW drive, and Samsung floppy drive (as incomprehensible as that seems to be to some people). Well, like I said, I've got all of that put together, and the case stuff all hooked up, but when I turn it on, not a damn thing happens, and the monitor says it's getting no input signal. Now, I've never built a computer before (I put it together with a friend who has), but apparently what's supposed to happen is the BIOS will load up, where I can then tell it to boot from the CD drive to install the OS. But, like I said, nothing even shows up on the monitor. Everything should be connected properly - the motherboard's light turns on, the video card's light turns on, all the fans start spinning, the case lights turn on... Just nothing shows up on the monitor when I switch it on. And I've tried on both my monitor and the aforementioned friend's. One thing mentioned to me is that it ought to beep when I turn it on, which it doesn't. The sound wires are connected to the motherboard (to the four red-orange pins in that group where the power switch, reset switch, etc. are connected to), so that might indicate... what? Someone please help me out here... I dropped about $1400 on this setup (and I was lucky enough to get a free case), so I'm a bit less than pleased, and a bit more than disheartened over the fact that it's thus far been completely unsuccessful. There are a few possiblities I'm considering, but I'm certainly no expert, so I'm hoping someone here can suggest what the problem might be. Or better yet, what the problem definitely is.
