Coming out of retirement.

Defo a hardware issue in there somewhere - have you checked the water loop for leaks? An x6 with a GTX460 is perfectly capable F@H hardware - i used to run a 1090T at 3.4 and a GTX460 without issue.

Check for simple things first - loose cables, loose RAM, working PSU and go from there - RAM will normally allow the machine to boot unless all the Dimms have failed together, as will a faulty hard disk as you should at least get the system to post

I put on my Big Boy pants, and tore into it.

The GTX460 card failed. On closer exam, it was full of dirt where it wasn't easily visible. Tore a 460 out of another machine, cleaned it, and voila, up and running.

Guess I'll know more in 24hrs.

There are several good programs for monitoring CPU and GPU temperatures, here is one:
Speccy - Download

There are also programs where you can control GPU parameters such as fan speed, frequency, voltage, etc. I use this one to increase the fan speed to keep my GPUs cool:
EVGA Precision X
Note that you have to create a user account to download, but that's free to do.

(EDIT By Mod: And it doesn't require that your GPU be assembled by EVGA even though their brand is on the software.)

Thanks!

I didn't even look at the temps before it crashed. OPPPSSS!!! I remembered that hot video cards fail easier than CPU's so I started there.

I will admit, after that, I won't put the shop computers on line. At one point I had 20 computers folding, most of them at work.
But non-business machines, I will fire them up.

Which current video card has the best "bang 4 buck"?

The GTX 680's are too much $$$. Looking for max folding at $200 a card.

PS: On the Linux side, you should upgrade to Ubuntu 64-bit.

Is there a reason for not using the 32-bit Ubuntu? It sees all the RAM, and I thought it was more stable.

Try a used GTX 580 they run slightly more than $200 on Ebay. Very high performance for folding. If that is too much try a Used GTX 570 or GTX 560Ti.

I just thought that since all your other OS's are 64-bit, and you've done fresh OS installs, you might want to make them consistent. For folding, there probably isn't any performance boost in going to 64-bit Ubuntu. And you would know more than I do about Ubuntu stability, I use 64-bit Debian v6.0.6 on two Linux machines here, and it is rock-solid.

The only reason is that fah requires a 64 bit version of linux to run the v6 smp client. V7 supports both 32 and 64. Depends on your client preference.
