Major video problem - Please Help!

[Roguer]

UPDATE: Read down to my last post

Hello everyone, I'm a longtime lurker of this forum and I just recently bought a Leadtek A6600 GT TDH AGP. I had nothing but problems with my previous video card which was a Ti4200, so up until I bought the 6600GT I was using a Geforce 2 MX400.

The problem is that in World of Warcraft I am getting a horrible picture (is this what "artifacts" are?). [Here is a Screenshot of my problem].

I reformatted my PC, updated my chipset drivers, installed DX9.0c, fully patched windows, installed the latest drivers from NVidia.com (I've tried older drivers as well), changed every setting in game, turned on/off AA and ansio, etc. I can't get rid of this problem! I haven't had a chance to install any other games to check if the picture is bad yet, but I'm confident it will be.

I received a notification from the Nvidia driver that my card was not receiving ample power so the clock speed was lowered for stability, so I'm assuming that my power supply is not cutting the mustard any more, but I am looking for a temporary solution (even if it dumbs my vid card down to the power of a GF4 for a little while). I have tried underclocking from 500/900 to 300/600 and nothing changes.

I am far from an expert when it comes to hardware, so I have no idea where to go from here. I want to be sure that installing a new PSU will correct this problem before I go out and spend money on it, and I would like to figure out if there are any alternative solutions/temporary solutions.

Here are my specs:
TurboLink LC-A350ATX power supply
MSI 645E Max mainboard
P4 2.8ghz (w/o hyperthreading)
40 Gb maxtor 7200 RPM hd
2x512 Geil 2700 DDR ram

Thanks in advance!

what is the idle temp for it? and load? do you have good airflow in your case?

 

[Roguer]

GPU core temperature: 46 C
Ambient temperature 34 C

The temperature doesn't raise a whole lot when loading the game (I haven't been able to "play" the game to get it hot). This problem is happening from the second the game is loading though, so I don't think it has anything to do with temperature.\

I have good air flow in my case. I've been testing with the case open also and no change

Id prob take it back and get a new one. if you reformatted and has the same problems its prob the card

 

[ricetek]

maybe its the generic power supply..

 

[Roguer]

I just read a couple reviews by people running 6600GT with 350w power supplies without any issues. I'm not ruling it out, but I'm not sure it's a power issue.

I have also confirmed that Splinter Cell Pandora Tomorrow has major issues also. damn!

 

[legcramp]

yikes.. i didn't even see your powersupply brand..."generic" hehe well the people who runs those 6600gt on a 350w psu, are using antec's or something... brand named ,...

 

[Roguer]

Does it make sense though that a problem like the one I am having would happen because of the PSU?

UPDATE:

This is seriously disappointing. I upgraded my PSU to a Fortron 350 watt and I'm having the SAME problem ((

Can anyone provide any insight? At this point I'm almost thinking it's my mobo. My GF2 works absolutely fine.

Try the card in another computer and see what happens.

This happened to me in WoW when I tried 458/1200 on my 6800 Ultra. I think you probably damaged your card

 

[mulpsmebeauty]

I'd be sending the graphics card back for a replacement meself

 

[Roguer]

Well, thank god I discovered the nVIDIA forums

The problem is that I have an SiS based chipset, and all currently supported drivers have major issues with graphical corruption with 6600GT and mainboards with SiS chipsets. I downloaded the beta 67.03 drivers which corrected my problem but caused my PC to randomly reboot during gaming, and then I downloaded the 71.25 drivers from guru 3D and I'm currently using those without any problems at all.

Anyone else with 6600GT problems, make sure if you have an SiS based chipset you're using new (beta) drivers.
