Silent Running: HW clock slowdown due to missing Auxiliary Power.

Hi,

My PC's spec is as follows:
A64 3000+ w/o oc
512M RAM
MSI 6600GT PCI-E w/o oc
1 80G PATA HD, 1 CD-ROM, and 1 DVD-RW
Antec 350W PSU


Yesterday, when I was playing BF2, my PC shut down suddenly for no apparent reason.

So I started up the PC again, upon entering Windows, a message popped up from the nVidia driver saying that the auxiliary power is not connected. Viewing the debug info in the driver it says "Silent Running: HW clock slowdown due to missing Auxiliary Power".

This is weird because I was always under the impression that the PCI-E version of 6600GT does not need auxiliary power, nor does it have a place to connect it.

So I kind of ignored it, and rebooted, and everything then seemed fine. However, after a while, I started noticing small black bars (I would say each about 20x3pixels, with 50pixels between any two vertically) on the left of the screen in any 3D program. I rebooted the PC several times, and it never went away. It was quite late at night, so I shutdown the PC and thought I would deal with that today.

Today after I started the PC, any 3D program I enter would cause artifact to appear everywhere on the screen. So I went to look at the temperature, and to my horror, the GPU temperature was at 103 degrees Celsius (CPU was at its usual 31 degrees; before all this, the GPU would idle at 40 degrees, and rise to about 50 degrees while gaming). I immediately shutdown the PC, and give it about 45 minutes to cool down.

I restarted the PC after that. After entering Windows, I found that the GPU was idling at around 60 degrees. I started World of Warcraft just to see if the GPU temp. would rise that high again. I played WoW for an hour or so, the temperature stayed at around 68 degrees. So I kept playing, and after another half an hour, my PC suddenly rebooted. And after the system restarted, there was artifact everywhere even at POST. I shut down the computer, and opened the case. The video card was untouchably hot.

After letting the video card cool down, I tried to start the computer again. Now, it wouldn't get past detecting HD's. The CPU fan would just stop, and there's still artifact everywhere on the screen.

Sorry for the kind of long post. Has anybody experienced something like this, or know what the problem is? Is my video card fried now? Thanks for any help.

it looks like your mb's not supplying enough power to the card

does the board have one of those 12v plug? (the ones you plug into the hd and optical drives)

if it does, make sure it's dedicated to your board

My mb is a Chaintech VNF4-Ultra. I doesn't seem to have any place to plug a molex into, at least not that I can find. And I thought only the AGP version of 6600gt needs an additional power plug.

well...try playing games while the optical drives are unplugged...see if it does the same thing

another thing that might happen is that the psu is overheating due to poor ventilation (happened to my antec neopower)

1) try playing games with the case open
2) try unplugging the optical drives and play games
3) if nothing helps....rma the card

Well, the thing is, I can't even get past POST now, there would be artifact everywhere on screen. Thanks for the suggestions though.
