My Ti4200 broke in a very very strange way...help?
Hi all.
Recently, my Leadtek GF4 Ti4200 64MB stopped working. Whereas it used to work fine in my Shuttle PC (the Nforce2 based SN41G2), recently when I removed the card (to clean dust off the heatsink fan) and put it back in, the Shuttle motherboard's 'AGP Protection LED' went on. After reading the manual, I found that this LED lights when the motherboard thinks you have a older 3.3V card in its 1.5V-only AGP slot -- it won't let you power up the machine in that state. Puzzled, I put it in another Nforce2 motherboard. Same thing: AGP protection LED on, no POST. Interestingly, the LED on that other mobo stayed on _even after the card was removed_. That other motherboard now works with its original card, but the LED remains on. I dont know if that's relevant, but it's odd. Now, I know that my Shuttle motherboard and its AGP are fine because 1) I can run the Shuttle perfectly with the onboard video, and 2) Another Gainward GF4 Ti4200 works in the same AGP slot. Coincidentally, I bought this card EXACTLY one year ago, on October 25th. This means that the warranty seems to have run out, and my email to Leadtek support has gone unanswered for 2 or 3 days. Does anyone have ANY clue whatsoever about this? What went wrong, and is there anything at all I can do to fix it? Any suggestions appreciated! |

I would look the card over very carefully for anything that doesn't look
right. The problem only happened after you took the card out to clean the fan. Also clean and check the edge connector. You can use a pencil erasor to clean the contacts on both sides. |

Several posts in the past about AGP cards not working til the were seated with more force than initially tried. |

Several posts in the past about AGP cards not working til the were seated with more force than initially tried. Take a look at the bottom edge of the card at the socket. You should not see any "gold" on the edge connector.... Sometimes the card latch feature will keep the back edge from going down... Bill |

Thanks for the suggestions, guys. The good news is that I've gotten
the card to work in two other motherboards now, one of which the card DIDN'T work on before, which indicates that the card is not itself entirely broken. But it still continues to light the LED when it's in my own shuttle AGP slot. I'm still totally puzzled as to why this is. As many of you suggested, seating is commonly an issue with AGP cards. I've had problems with AGP cards not seating properly before, so I paid special attention to that, and I've made a visual inspection of the contacts along the bottom and on the PCB itself. What I'm confused on is why it would be broken enough that it wrongly sets off the 3.3V AGP LED but can still work on 2 out of 3 motherboards. I'll keep looking for any obviously physical defects on the card. |

Sounds like it is not seating properly. If it worked before you took it out,
what else could it be. "porpoise" wrote in message om... Hi all. Recently, my Leadtek GF4 Ti4200 64MB stopped working.
