Need Technical Help: New Motherboard Woes

[AppyPappy]

Here's the deal. It's new set up. Gigabyte GA-7VRXP board, 1500(1.33ghz) Athalon, ATI Radeon 7000 board, 256DDR RAM. When I boot the machine, I get...nothing. No signal to the monitor. Everything spins up but no signal. The monitor never comes off power-saving mode.

Note: I have not set the jumpers for the processor because they didn't come with instructions for the settings for the chip. The voltage is set to something called "Auto"(by default). The FS is set to 100(by default).

I have not changed any of the settings for the board.

Note: This is the same thing that happened with the machine I am replacing. It would boot but nothing would happen. I checked the monitor and it is fine. No other parts are the same between the two machines.

I tried to post this in chat. If it gets somehow to News, would the moderator slap it back into place.

I have a motherboard problem recently. Try disconnecting everything that is connected to the computer other than the keyboard, mouse, and monitor. If it works that way then turn it off, add a device, and turn it on. Keep doing this until it doesnt work. Then you will have found the problem device. This is a problem that happens when you 'daisy chain' things. If you are doing that. If you are not doing that and this trial doesnt fix your problem then someone who knows what they are talking about will have to help you.

Everything has been pulled. I have a yellow light next to the ATX connector but I can't find out from GigaByte what that means.

Sounds like your video card. Did give any beeps when you powered it on?

[tacticalogic]

Does it run the POST tests? You should see it flash the lights on the keyboard, and access each drive in turn as it tests them. From your description, I'd suspect the video card first, although it could be any of the other cards or drives. Since everything spins up, it sounds like the 12v side is OK, but if you've go something shorted out in the 5v side the power supply would detect that and refuse to power the logic circuits.

Does it have onboard video? Try plugging your monitor into the onboard video connector and see if that works.

[AppyPappy]

No beeps. I'll try another card but I had the same problem on the previous machine, which I am replacing with this machine. It's a Cyrix333 and it suddenly stoppped working one day. So I replaced it with a new machine which I am building. Here are my two latest theories : 1) The outlet has gone bad 2)one of the risers is touching the board somewhere and causing a short.

[AppyPappy]

No onboard video.

[AppyPappy]

No flashing lights and the drives are not connected.

Have you tried to reseat the video card and memory?

[tacticalogic]

I think your next step is going to be trying another video card, or at least pull the one that's in there out and see if it will power the processor and try to run POST tests.

Check to make sure the circuit pins that stick through the mother board are not too long and are shorting against the box.

This site should help you.

Also, check the power supply...that is if you had the same problem with another board.

That was my thought too. So far that's the only thing Pappy hasn't mentioned specifically as being new.

different monitor too right?

Try to change the speed of your motherboard to 133Mhz instead of 100Mhz default setting.

[AppyPappy]

Done. I set the clock speed and the FS. No change.

First rule of troubleshooting...."Break it down to a minimum system"

In the case of a PC a minimum system is:

Power supply, mother board, (not mounted in the case but set on a non conductive surface ..the top of the MB cardboard box is great) CPU (with cooling fan VERY IMPORTANT WITH THE Athalon… they will cook in a heartbeat), and memory(minimum amount)only

..this config, if it comes up, should give you beep codes…. but get your Motherboard manual first(go to the MB makers web site) and CHECK YOUR SETTINGS FIRST including you memory config (what dimm slots)... do not alway trust what is labled on the MB this is sometimes wrong

… if you do ger beep codes in the minimum system power down and add the video card only… power up and see if you get a display … if you don’t do you still get beep codes? if no beep codes the video card could be hanging the bus/holding the system down
