6600GTs going out?

Here's my story.

About 2 years ago, I built a partially new computer for myself. Gigabyte K8Triton, LeadTek 6600GT, 1GB Memory (2x512mb Corsair), DVD Burner, 200GB Seagate. Soundcard came out of my old system, so did the floppy drive that I rarely use.

Everything was fine for 19 months, one day after leaving Warcraft on while I went shopping, I came back to see some horrible video tearing issues. It was flickering and looked like someone had cut the screen and laid the pieces kinda back together. Well 2D apps worked fine, it was only 3D apps that this happened in. I contacted LeadTek through their website, got a new card after shipping mine in. The replacement card had an issue right away, it made noises minimizing/maximizing windows, and a horrid clattering noise during any 3D app/game. I contacted LeadTek again through their website, again sent it in and got another replacement.

I've had this replacement card for almost a month now, two days ago it started acting up, so I decided to try Counter Strike: Source stress test, and it started jumping, locking, and losing textures. Today, while playing WoW it started locking up, typing was really slow, video and textures starting cutting in/out and finally my system locked. I rebooted and was treated to garbage characters appearing and disappearing on the screen. I rebooted again, this time all the "DOS" text was just garbeled dots. Rebooted again and here I am now, wondering is it most likely just the cards, or has my system some how mysteriously came up with a way at eating this replacement video card?

My original card obviously overheated at some point, because when I was testing it out, the fan was making weird noises. The first replacement obviously was a bad card because it did it in my system and my friends system. This last card however, lasted a month, I thought maybe it was my OS and drivers causing some slowdowns as after I reloaded my system, it was fine, except in large raids when my text typing would slow down.

Sorry to ramble, but anyone think of anything I might want to check out? Or should I just assume LeadTek's refurbished cards suck, and I need to fork out another $10 for a replacement? (shipping cost that is).

Ok, but how do I prove whether or not its the PSU?

And, do I still go get the video card replaced?

It's the PSU. I had the same issues with my 6600gt before it hit the graveyard from use. I would think that the video card is still ok.

Sorry, I just wanted to be sure before I started spending money, chasing my tail. Since the card isn't directly connected to the PSU, I figured I'd be seeing more issues than just the video issues.

Yep, pretty much settles any debate there.. even high end TT psu's arn't great, but that thing is junk.

Now lets hope you didn't fry another video card with it.


Well, it always comes down to opinion...I've had 2 of these for an extended amount of time and have had no issues whatsoever.

Build 1
P4 2.8
1.5gb Corsair PC3200
80 GB Maxtor IDE
400 GB Seagate 7200.10 SATA
Leadtek 6600gt AGP

Build 2
AMD 64 2800+
1 GB Corsair ValueRam
80GB Western Digital SATA
Leadtek 6800le (Unlocked pipes and shaders and overclocked)

Both systems are used for about 20-40 hours of gaming a week (not me although I wish) as well as many other general tasks and have been running for over a year with this PSU in them. Blaming this PSU is just poor judgement.

Let's test the PSU shall we? That would be a good place to start. Get a volt meter out, turn on the computer and run an intensive 3D app. Measure your 12 volt and 5 volt rails. They should not be any more that 10% above or below 12 and 5 volts repsectively. If it checks out then you know that the PSU is not the problem...

Thanks modular, thats the information I was looking for, however now, sometimes it will boot up fine, but dies shortly in 3D apps... and sometimes it will try to boot, but all of the text from the video bios start, to the bios, to the detected hardware at the bios screen is garbage characters.

Ok, I have gotten a meter, my PSU is giving 12.17-12.25 on the 12V and 5.16 on the 5V this is testing from a molex.

Any suggestions? Probably just crappy cards?

Any comments at all?

Booted up the system, it came up fine, and those are the readings I got from a molex from boot up till I was in and loading WoW in Ironforge.

Also, I tried using some video stress test first, but it wasn't registering anything, so then I launched WoW, graphics seemed sluggish, but the readings were still 12.17-12.25
