No Green, Only Red and Blue??

By 412Know,1 Must Seek ·
Ok, I've got this p4 mobo (PC chips)and an Intel 1.5ghz CPU. I bought the machine as is at the time. I got around to checking it out, afer discovering the FDD cable was reversed, it seemed fine. I tested all the components and ran HD and RAM checkers...no problems. I go to close the machine and stand it up, The Green goes out and I have tried several known good Video cards I have on all available slots (all 2 of them)there is no AGP slot, just a small Video jack that plugs into a rectangular pin socket on the mobo. I know I had this problem with anoher mobo, but can't remember how I fixed it. Oh, and there is no setting in the bios to disable the on-board video, that I can see. Any suggestions? And while Im on that subject, I had a few that won't show video at all. How would I know if it is a bad mobo or a bad cpu without being able to swap them out? I use all known tested and working Video cards both pci and agp. Thanks!

Seriously, I wouldnt waste anymore time on the board, that's the problem. You bought the pc with the backup plan to harvest it for the parts. Spend $50 bucks on a new motherboard and reuse the parts. You got a sweet deal on a good working processor, hdd, and ram. You have known good monitors and video cards. Dont destroy them plugging holes in a sinking ship. Let it sink. You can find great OEM deals online like www.newegg.com
Curious, if it doesnt have an AGP port where were you sticking the video cards? UNless its pci express which I doubt based off your processor. This rectangular pin socket, it supports your other video cards? If there is no Bios turn off attribute for the onboard video or AGP port then its an unscallable pc. Well this is my .02 in the matter it sounds like the onboard video jack is damaged, save your time and get a great deal either online or at a computer show and you will have more options to make the pc last longer on a minimal investment.

This was the strangest MOBO I have seen for a relatively new one. It only has 2 pci slots. No AGP and little 1/2 socket for a specialized modem. Very inflexible. I finally tracked it down to a PC chips manufacturer. I had to actually remove the board and on the bottom, there was a small ID number.. I wrote them telling them If I had put out such a board, maybe I would have hid my name as well.. :)

This is the reason OnBoard video should be outlawed!.. anyway...

OnBoard video has 3 methods of being turned off. Inserting a REAL video card, jumpers, or BIOS. There is a fourth way, but I've never been able to get a sledgehammer to only crush the vid chip.

I'm inclined to agree with the electrical short theory. I'd say check the connectors on the vga connector, but if you're getting the same problem with a normal vid-card, you're not using the onboard connector anyway.

Check to make sure all chips are seated is kinda dumb, but can never hurt. (Unless you leave the power on and do it after washing, but not drying, your hands)

Pull the MB out, and put it back in making sure all the posts are secure and the MB has no bend or bow in it.

Have you thought of maybe just running it lying on its side?

To find out the maker of the M'Board you need the BIOS String on the bottom of the monitor during the POST. You need to copy this down completely and usually press the pause button on the keyboard so you can get it correctly. As you already know the maker of the BIOS you can look on their Web Site for a maker by the explanation of the BIOS String or try

http://www.biosman.com/

and follow the links to the BIOS Maker and then the listings for the M'Board Maker as described by the BIOS String.

Firstly to see if you do have a problem with the M'Board or just the way it has been mounted I would remove it from the case and plug in a PS and just add a click switch to the Power On pins to start it laying on its side on an anti static surface. Once you have it running you can then tip it onto its side to see if the problem persists but I'm betting that you'll find it was badly fitted to the case or some crud has shorted out the back of the M'Board and is causing the problems. O good clean out will never hurt but remember if you use compressed air to hold the fans still to prevent them from destroying the M'Board as they spin and generate power.

Lets know how you get on.
