Dead 6800GT?

[SuperDave1685]

Hey there guys.... Having trouble over here with my video card in my sig... It all started last night when I fired up Rainbox Six 3: Raven-Shield to play with some buddies. The screen was flickering on the main menu screen and the sound kept freezing and stuttering... So I thought that it might have been the new XG drivers i installed... uninstalled them, ran driver cleaner, and re-installed.... no luck- same thing... welll today, it did the same thing, even after many chipset driver uninstalls and reinstalls, BIOS resettings, etc.... So on one restart, it failed to POST... just one big beep... "GREAT!!!" :mad: :mad: ..... sooo, finallly after an intensive removal of the Artic Silencer rev. 5 and a good cleaning (about an hour) of the card to clean off any thermal goop that might have seeped onto the card, I got it too boot into windows.... BOOM! Nvidia Sentinel pops up and tells me that my video card isn't receiving enough power so it has backed the card down to prevent damage to the card...I played BF2 for about 15 min then when it started to artifact... so I turned off the PC... Turned it back on and during the startup, the screen went beserk on me- checker boards, lines, etc... the sign of a dead card!! :bang head: So I rebooted hoping it was a fluke.. success! I got into windows, but I can't click on anything, otherwise the system freezes... everything is at stock in my PC right now, so an OC'ed CPU isn't the cause... The temp tab in my driver panel says the card is idling at 50C.... so its not overheating... BTW, my Power Supply is an Antec Neo Power 480W, with 18A on the first+12v rail and 15A on the 2nd +12v rail... surely the PSU is cranking out enough juice!!?? The PSU is only about 5-6 months old... Any help would be GREATLY appreciated!!!

You sure the molex connecter is connected right?

Update.... Well I'm sitting here in windows just danady... no problems at all, but when I go to play a game, it goes haywire and freezes and I have to Alt-F4 out. Yes, the molex is connected securely.. the card infact has its own dedicated line coming from the PSU....

*edit*
About a week and a half ago, I tried running the AGP bus at 75Mhz and @ 1.6v to see if I could get a little more outta my card- no such luck... I figured if that woulda damaged the card, then surely it would have shown right away?? :shrug:

If it's working in everything else, and not the game, that points to game issues. Try to relaod the game, and look for patches. Also if you are OC'd, back off the OC sokme. You need to eliminate variables and if your OC'd is complicates things. Some games do not like high OC's, and others will tolerate it.

i would also try a different video card, borrow one from a friend or use a lower end one if you have it lying around, if it is still doing the same thing then it would rule out your video card as an issue and you can move on from there

Well I backed down the card to default clocks and it looked like it likes that... at least for a while.... I left my computer last night folding after I got done playing Counter Strike Source...only to wake up in the morning to a hung system!!! :eh?: So.... I reboot and BAM! checkerboards all over the screen... Apparently, the card was on its last leg and peacefully died in the night... :cry: Sooo I bought me an Ati X850 Pro from Circiut City today.... gonna attempt to unlock the extra 4 pipes tomorrow (if my wife lets me on)... Damn, thats 2, TWO! 6800GTs that have died on me in LESS than 2 months! Talk about bad luck!!

man that sucks, sorry about your bad luck. I am curious what you think is killing your cards though. Could it be some sort of power supply issue, a motherboard issue, or something similar? I would hate to another card get killed if its one of those components.

[SuperDave1685]

I'm pretty sure that this card died because of my OC.. which wasn't even that much- only 400/1100 compared to the stock 370/1000..... cause as soon as I flashed it back down to the original BIOS, it seemed ok ... The first 6800Gt was an eVGA. It died because of static discharge.... boy was I mad at myself!! :bang head I can't believe I forgot to ground myself while working on it! It was a good card too, ran at 420/1200 24/7 rock solid with no volt increase... :cry:

Sounds like you killed the memory, my BFG 6800GT would reach 400 fine but the memory didn't like anything more than 1080. It also could have been after you installed the arctic silencer, I've killed a Geforce 3 by applying a little too much arctic silver on the memory :shrug:
