So, yeah, I finally got a semi-constructive response out of Leadtek about my balky Leadtek PX6600TD video card. After eight and a half months, with three and a half months of manufacturer's warranty to run, they have conceded that there might possibly be a problem with the card, and have told me to return it to the original vendor for test and/or refund. The vendor's 30-day warranty expired, of course, seven and a half months ago.
I've contacted the vendor citing the original invoice, my mail to Leadtek, and Leadtek's response (reproduced here). We'll see what happens.
Me, to Leadtek:
I have a PX6600TD, purchased new in February. It appears I got a card with obsolete firmware; the firmware version on the card is much older than the version downloadable from your web site. Ever since I bought the card, it has suffered from random video lockups that usually (but not always) crash the entire machine. When I've tried to update the firmware, the update utility refuses to do it, and you've simply told me "Don't update the firmware" without offering any alternate solution. I have exhaustively tested the machine's RAM and it's fine. Every indication is that the video card has a problem.
I've put up with this problem for eight months now, and I'm tired of being told "It can't possibly be our card at fault". I refuse to spend a thousand dollars to swap out the entire rest of the machine just to verify that the problem is the card.
This card is still under warranty for another four months. I want to know whether your warranty is worth the paper it's printed on, and what you're going to do about getting me a card that works and doesn't crash.
Leadtek's terse and somewhat garbled response to me:
Please direct send back the card to test or refund in original dealer where you bought.
Thanks for your incoming letter!
