only fans work on motherboard

June 6, 2010 at 09:58:06
Specs: Windows XP
I replaced the CPU fan with a Evercool 70x70x15mm ball bearing 3 pin fan, and I put a hard drive in. When I started the computer, only the CPU fan and the AC power fan went on.

We have no idea what you did, but I'm pretty sure that you did something wrong.

I am trying to fix this computer (an Intel (GA-8GEM667K P4 Titan-DDR MOTHERBOARD). It was a gift. There was no fan on the CPU and it did not have a hard drive in. I turned the computer on for a short while to see if the motherboard was working before I spend money on it. It worked fine until I added the CPU fan and the hard drive. When the CPU fan and the PS worked and nothing else happened, I did the following:

1. Removed the rams (memory) and the battery. Covered the rams as well as the battery with paper from the inside of a cigarette box. (The white side of the paper on the outside and the shiny side touching the ram and battery). Rubbed lightly over all parts of the ram, especially the insertion part and left it covered like this for about 20 minutes.
2. Removed all cards and cables, leaving only the CPU (without the fan plugged in).
3. Removed jumper from the CI jumper pins
4. Removed jumper from CLR-PWD pins
5. Unplugged the monitor, keyboard and mouse
6. Removed the screws holding the motherboard. Lifted the motherboard from the case and put it outside the box on cardboard surface.
7. Cleaned the bottom part of the case and made sure there were no loose screws, wire or metal parts inside the case.
8. Cleaned the bottom of the motherboard (rubbed very lightly) with the shiny part of cigarette-box paper (to make sure there’s no electrostatic discharge) and inserted it back into the case. I used non-magnetic washers with the screws to fasten the motherboard to the case again. The motherboard does not make contact with any part of the case
9. Removed one of the rams from the cigarette box paper (made sure not to touch the ram with my bare hand), and inserted one stick of memory into the no. 1 slot on the motherboard. I made sure it is all the way down and locked in place.
10. Waited for about 10 minutes and then plugged in the AC power and switched it on by wall. Then I switched on the computer and let it run for 10 minutes
11. Switched off the computer, and removed the plug from the AC power supply again and left it off for 20 minutes.
12. Used the same cigarette box paper again and “cleaned” all metal parts on the expansion (AGP) card. I was careful not to harm any small parts on it. I held it by the part that fastens to the case and didn’t touch the card with my hands.
13. Aligned the AGP card to the onboard AGP slot and pressed it firmly down on the slot to insert the expansion card. I made sure the AGP card was locked by the small white- draw able bar and fastened the card with its screw to the case.
14. Plug in the mouse, keyboard and the monitor, waited for at least 20 minutes for static to clear and switched it on again.

As I said, only the fans work. The monitor stays black and the keyboard and mouse lights don’t go on. The CPU does get warm and so does the AGP card. I have no idea what else to do.

OK, you were given a dead computer. You then danced with it for a few hours taking it apart and cleaning all the parts.

Right so far?

Then you reassembled the thing and it started up and ran for 10 minutes without the agp video card and with one stick of ram and the onboard video worked just fine.

Am I still on the same page as you?

You then installed the agp video card and no video.


So some possibilities are crappy power supply, 4 pin 12 volt connector (2 black and 2 yellow wires) not plugged into the motherboard, bad agp video card, an AGP 2 card (must be AGP 4 or better for this motherboard), you bumped something, or you did something else you didn't tell us about..

Do you hear a single beep at startup?
If you remove the agp card, does it work?

I see where Zybella ran the computer without a CPU fan for some period of time. Although I didn't think that was possible maybe some other fan was connected to the CPU header. If that is the case fatal damage may have resulted.

Possible OtH, but it did apparently run for 10 minutes and an Intel chip will try to protect itself from frying by shutting down.

I do know a guy who did just what you said and he also restarted his machine every time it shut down. He did eventually fry a 3.0 Prescott...the heat spreader looked like it had been heated with a torch.

Thank you all for your advice. The computer ran for ten minutes without a CPU fan, BEFORE I took it apart. The video card also worked fine. The computer stopped working only after I installed a CPU fan and a hard drive.

I have been all over the internet to learn what I could find about this problem, but could find nothing that helped yet. How can I test the CPU without removing it from the board? If anyone knows something that is not mentioned above, please help! I can not believe that I could fry the board, or anything else, just by adding a hard drive and a fan to the heat sink.

Disconnect the hard drive data and power cables and try again. Could be a problem in the HD controller or the drive itself. Take it out of the equation.

When troubleshooting only make ONE change at a time.
