My leadtek (winfast a400 GT TDH) geforce 6800gt is doing crazy things

It is called a "VPU Recover". There was a system fault, and the ACPI restarted the card. Afterwards it runs on standard mode Windows drivers.

Swap the card out ... (Return to supplier for exchange).

BTW if anyone wants to throw their faulty card away - pm me. I will take it and see what the real problem is ... maybe I figure out a fix for everyone that has problems. If I manage to fix the card, I will reyurn it to its owner.

Thanks Ruder. In the end I bought myself an XFX 7800GT...and an Athon64 etc It's a ripper. I'm not using the 6800GT in my work PC and it is working really well. The second time the card died was because of windows, not the card itself (It was a good excuse to upgrade though

I've finally got the email from ups saying that the card is on the way to my home.. so if it takes 2 weeks like it took for the card to get to leadtek, ill probably receive it on january 17th.

I hope it will work and if not, I'll try what some of you tried, put something under the card to keep it in the slot. I *hope* it's a weight problem, because it's not such a big issue.

*sry again for my bad english*

I have the 6800 which ran fine for months, then the random boot up artifacting mentioned countless times before.
Unfortunately i don't have the warranty so i REALLY hope it is the weight of the card that is screwing it up, becase after sometimes pushing the card up Windows will boot fine.

(And sorry for adding another useless post to this 8 page thread :dead: )

Another Card With Problems

Just figured I'd add on the misery.

I bought my Leadtek A400GT in January (2005). From Newegg, of course. It worked fine (HL2 was gorgeous!) for about 10 months.

Then...I got garbled image and artifacts, just like most people in this thread.

Tried a bunch of differnet solutions, didn't work. Tried two different video cards, and they worked like a charm.

Currently am using a GeForce2 (32mb).

Sent my RMA request today with the form that was linked to earlier in the thread. I hope they don't give me **** because it is so close to the 1-year warranty ending. Though they shouldn't, given the fact that they clearly sent out a defective batch.

hey... i had **** happening wih my geforce 7800 gt the day i installed it ... all my games have tearing, artifacts, w/e all over the screen, i have an rma forum now, but where on my graphics card is the serial number????? it dosnt say serial no. anywhere on my card... also, i want a replacement, what box do i choose?

1. Return for Repair: 2. Return from Eval:

usually there is a letter sticker on the back of the card with the serial number on it.

Check the Return for repair box. I did twice and they rma'd the card..

If there's anyone looking at selling their dead gfx card, please PM or email me.

I had the same problem, and after initial reluctance (they tried to get me to go back to the retailer) Leadtek RMAd my card back to Holland (from UK) even though it was over 1 year old, fixed it, and promptly sent it back - less that 2 week turn around.

So I am pretty happy - they fixed my out of warranty card for nothing.

Hi everyone,

Am new to this forum and actually got here while doing some further research on Leadtek's 6800 series issues. I got a new 6800LE back in September 2005 and as of this minute (Jan 2006), I'm still going through RMA with Leadtek just like others described. It is quite sad that after 3 months, 50+ (including a couple to the BBB) emails and one defective replacement unit, I'm still without a card. They said I should be getting one in a few days, I wouldn't be surprised if replacement turns out to be defective as well.

What good is a warranty on a product that you cannot use, I wish someone had a contact phone or fax # for their CEO. I'd like to send a letter to him or someone that'll really look into this issue from a preventative stand point, I could care less at this point if they resolved the issue with my card as I'd already made up my mind not to buy any Leadtek merchandise again. It just feels awful after what I've gone through to see someone unknowingly end up in the same situation.

Do your self a favor and stay with another brand.

Yesterday my A400 came in the mail. Less than an hour after opening the box, I found this thread, and only wish I found it much sooner.

Garbled characters at post, and no amount of bios tweaking through the other card, nor trick offered in this thread induced the card to do anything beyond the garbage-filled screen. Once I let it boot through to windows, where I could make out my desktop through a haze of green lines. When I decided to install the latest drivers (what the hell, it was worth a shot), the screen went black and stayed that way until I hit reset.

I exceed minimum requirements for everything.

Now, I knew this card was big and heavy, but after feeling it in my hands I honestly have to say I wouldn't be comfortable with it running in my system even if it functioned. It seems like it would rip the AGP slot off the motherboard.

And it's such a shame, because my Ti4600 is a Leadtek, and it's been extremely reliable across two owners and thousands of miles of travel in and out of an AGP slot, plus THOUSANDS of hours of heavy gaming. I wouldn't replace 4600 if not the absolute minimum requirements for some games being higher than this card.

Anybody who read through this entire thread probably gets the hint by now that they should avoid this video card. I wanted to add my own warning though. If I saw this thread before purchase, I would have gone with something else.

have you tried to hold it and lift it a bit once installed just to be sure that the contacts between the card and the agp slot are correct ? Some of us here put something under the card to keep it correctly in place and they resolved the problem.

try to hold it without the screw that joins the card to the case. When I installed the card, the screw moved it a bit... at the moment I didn't think it could make a problem since I hadn't read this thread.

I tried like a dozen variations of "hold the card up", screwed in, not screwed in, double, triple checked for any collision with wires inside, any other potential pressure, also airflow.

I tried the fast write settings, AGP voltage settings, multiple dedicated power supply connectors... an exausting venture considering with every combination of bios settings I had to swap the whole thing out with the poor 4600 just so I could see the bios.

When my Ti4400 died, it did the same thing: garbled post.

Then theres no solution??

Im suspect that someday one of us will come with the total solution, i hope that is not to trow the card to the garbage.!!! :evil:

After 1.5 year of faithful service, my Leadtek 6800 GT died aswell a couple of days ago, and there is absolutley nothing i can do with it right now. Windows desktop turns into a colorful net, a few seconds after boot.

So much for Leadtek and their 1 year warranty. I guess the card's not totaly useless yet. I asked the card if it would like to meet with my hammer and the system crashed, so i will take that as a yes. :stickout:

I dont think that someone will find a solution if squiddie has tried everything he told us. The card is probably just faulty and there is nothing to do with it but hope for a functionning card. Ill receive my 3rd leadtek a400 gt next wednesday (january 11th). Be sure I'll tell you what's up with it. All these previous replies make me think that my chances to get a working card are weak.

Hi all, i believe to have a similar problem to the above, although slightly different, my card (a Leadtek A400GT) has worked fine for the best part of a year now, but just recently it randomly crashed and i had to power off to reboot.

When rebooting, all is fine, and windows loads up, but the moment windows has loaded it will be fine for a few seconds max, then the whole screen will become overlayed with a garbled mess (i can still move the cursor briefly in this state, sort of behind the mess) the system then crash's and reboots.

I can load perfectly into safe mode however, which led me to believe that this must be a driver issue (even though i hadnt recently changed anything in my setup) so, as i was planning to format soon anyway, i formatted all drives and reinstalled windows, all is fine i can boot into windows now, i set up my network to get online and installed all my drivers. This worked fine, but as soon as i installed my nvidia drivers (I tried the winfast ones, 66.93's and the latest 80.xx ones, so far) and rebooted, i get the same mess when attempting to boot into windows normally...i meet all the minimum specs for the card, and as i said its been fine for a year. Im just very puzzled as to why it works fine, no corruption etc (i can even play video files) until i load some nvidia drivers into the system, and im looking for someone kind enough to shed some light on the matter

Any help is much appreciated,
Moogie

My kingdom for a working A400

My first post here and I am sorry to say it is a sad one.

I am/was an avid Leadtek supporter. I'm growing on in age here and when I find a good company I tend to stick with em. I've got three machines and various others at my company all with Leadtek products (some reaching 5 years old now). However, I purchased an A400 (AGP) in the beginning of December and I experienced the weird chars and lines upon boot-up.

I've done everything I could to try and rectify it and searching Google brought me here (back then). Since I had already RMA'd it to Leadtek there was nothing I could do. I've just received my third card about 1 hour ago and am sad to say it's a bad one. The second was by far the worst, but I will not "live" with this kind of odd behavior from a $180 part. I've been following this thread religiously and just want to throw my experience on the pile (it's some sort of therapy for me I guess ). I originally thought "ah.. maybe it's just finicky". Every card I received, I tested on three completely different machines. All had the exact same result - despite power supply, AGPx4/x8, bus speed, etc... That can only mean one thing: a bad product.

I loved Leadtek products and they 'were' always stable and effective. I am not one to listen to the younger crowd and play the "your brand sucks" game. However, I am a business man and when someone drops the ball.... and HARD. It's time to move on.

Goodbye Leadtek. I appreciate the good memories but these bridges deserve to be burned. :hotbounce

Ok I've just installed the card and it seems to work well. I've tried bf2 with everything at high and it hasn't crashed yet . I'm happy but still, it could crash tomorrow, next week or next wonth without advertising... You should understand that I don't trust this card yet .
