Need Help with New System Build

[REDCHAOSTRY]

Hello,

I am building a new pc for myself (this being my 3rd self built system) and I have run into a problem. I put the system together and attempted a power up with no luck, but I did have have power led light up on motherboard. Troubleshooting lead me to the power switch (behind the face plate button) being unseated. Seated the switch correctly and re-attempted a power up. Now I have a new problem. Any help or advice would be greatly appreciated.

This is the current status:

Mainboard Power LED On
CPU Fan On
Chassis Fans On
Power Supply Fan On
No Video Out
No Post messages

I have tested the Power Supply and Video Card in another system, and both work fine. I have no way of testing the CPU, memory, or motherboard, in another system. I have disconnected all devices but the Video Card and Keyboard with no change. If you need anymore information about the system, please ask and I will gladly provide that information.


System Components
Mainboard - Asus K8V SE Deluxe
CPU - Athlon 64 3400+ - with retail heatsink and fan
Memory - Muskin PC3500 Level 1 Dual Pack (512 x 2)
Video - BBA ATi Radeon 9800 Pro 128
Power Supply - Antec True Power 480 watt
Case - Thermal Take XaserV WinGo 7000A
Sound - Sound Blaster Audigy 2 ZE
DVD - NEC 2500A
HDD - Western Digital Raptor 74 GB SATA

I thank you for your time, help, and patience.

Did you wipe the BIOS?

Welcome to AnandTech, BTW

Yes, I wiped the BOIS, following the procedure from the motherboard User Guild page 2-19.

try one stick of memory in the blue slot first. You can;t try the memory in another system ? That should work in almost any system of the last 5 years ! (any DDR system)

Thank you for the suggestion, I will try it as soon as possible. I forgot that putting the RAM into a slower motherboard, will just underclock it from its rated speed.

It may be that your motherboard is shorting out. Make sure the board is not touching the case or any other metal component. This happened to me once, with pretty much the same symptoms you describe. Disassembled the whole rig and found I'd left one too many spacers under the motherboard . The spacer was touching the back of the motherboard, shorting it out. No permanent damage was done, fortunately -- just removed the spacer and the machine booted up fine after that.

Also confirm that

• your ATX12V cable is plugged in
• your power supply is set for the correct input voltage for your area (115 volts or 220 volts)
• you don't have any EMI springs sneaking into your motherboard's jacks (the springy finger things on the I/O shield)
• your video card is fully seated in the AGP slot, not just halfway down (two rows of contacts in there) and that the video card has its auxiliary power pigtail plugged in
• your mouse and keyboard are plugged into the correct PS/2 ports (it matters which one)
• and that you don't have your case's front-USB wiring plugged in incorrectly (suggestion: unplug it for now and see what happens)
• also, if you have any very-low-RPM fans plugged into the motherboard's fan headers, such as thermally-regulated Enermaxes or a slow-running PSU fan, unplug them as a troublshooting step... my home system won't POST or run if I have an Enermax 80mm thermally-regulated fan plugged into it, because the RPM signal is so low that the motherboard gets

Hope that helps

Thank you all for your help. The new rig is up and running well. mechBgon it was the ATX12V cable, thanks to you for pointing me in that direction.

Sweet, enjoy your new rig
