Problems booting new PC

I recently built a PC with all new parts except for the hard drive & DVD burner. The PC has a 600W power supply w/ a 512 MB Gigabyte video card and and an AMD +6000 X2 processor. When I boot the PC, I do not hear a boot up test "beep", nor do I have a display. The processor fan & power supply both spin like they should. I also have a system fan that does not spin, I currently have the system fan plugged into the mother board for power.

I have swapped out other motherboards from working PCs an they have the same behavior as my new motherboard. I have tried different power supplies which give me the same result. The only common component between all the different ways I have tried building the PC is the actual ATX tower. I am beginning to wonder if all the boards are short circuited against my ATX tower.

I would appreciate any advice if anyone has ever seen a problem like this. Thanks!

The most common problem I see in new builds is the missing insulating washers on the underside of the MOBO. I use plastic or nylon standoffs to eliminate this problem. Also, a video card with 512 MB will require another power cable from the power supply directly to the video card. Try to keep any fans external to the CPU or video cards plugged directly to the power supply, drawing too much power through the MOBO could starve some ares of the MOBO and if too much is drawnn, it could burn some traces off the board.

Or stuck in the ON position.

All you need to check this is to unplug the Reset Switch from the Header Strip and see if you now get a display.

You will also need to attach any additional Power Plugs that the M'Board has fitted so if it has 3 X 4 or 6 Pin Plugs beside the standard ATX Plug you should make sure that the Power Supply is plugged into every one of these sockets.

Otherwise do as mentioned in the above post.

have the problem after the above great anawers, disconnect the system fan, drives and anything else (except video card and memory-you have tried each memory chip individually, haven't you?).

If it does not POST properly, check the video card MB jumpers, then a different working video card if you have one.

If you POST properly, add things back one at a time and hopefully you will find the offending member.
