Turns out my brother logged onto the computer, causing 'the system' to no longer have access to the folder where work and cores are stored. This happens even if my user is still logged in. Weird, but anyways, that's it. :)

My GPU2 client on the 8800GT has started to go idle with the following message;

[xx:xx:xx] EUE limit exceeded. Pausing 24 hours.

A workunit goes to 100%, then it sends the results, get a thank_you, and attempts to load new work. It then dumps an error;

[xx:xx:xx] Folding@home Core Shutdown: UNSTABLE_MACHINE

It doesn't happen during a workunit, but in between when it tries to fetch new work. What's the reason for this? I lowered the 8800GT to stock, and it still happens. If I restart the client, all is good until the first or second work unit is done and sent.

Any suggestions? :confused:

UNSTABLE_MACHINE and the rest of the spam continues 5-6 times and dumps out in the EUE limit exceeded.
 
I've seen that happen when the clocks are set too high. I don't know why this error would remain at stock frequencies. Try doing something else with the card that's GPU-intensive like playing a game or watching high-def video and see if other problems surface.

 
I have had this problem on a Dell box. I cannot get it stable running with 1 or 2 SMP clients + the GPU client. I have settled to just having a GPU client and a standard FAH running and it seems to be ok. My guess is it is a heat issue, one of the things that tipped me off is when touching the back of the PC by the video card, I received a mild burn! :D
 
I was getting this a little while back and fixed it by dropping my OC down a bit. Now that the heat has hit full blast, I realized that I got that error again a few times last night. I'm dropping the clocks a little more to see if I can't get the heat down enough.

FAH will push your machine beyond what any other stability test will.

 
With the GPU2, it could also happen that the client became borked and it will always do that no matter what. A full uninstall and reinstall usually fix this.
