Out at dinner right now

Have you tried setting it to not sleep.

If yes does it go to "sleep" anyway.

Thanks for the suggestion. Made the adjustments. Will see.

This board rocks.

If it still goes to sleep, freezes or shuts down then check the fan and airflow, make sure it's not getting too hot.

After adjusting the sleep mode to "never", it still exhibits the same symptoms. Fan and air flow are fine. In fact, I've removed the side cover to provide max. air to the fan. I have previously run a status utility program that provides temp. readings in various areas of the computer. Seemed okay at the time. This system has a water-cooling feature, but if there were no abnormal temp. displays, I assume it's operating okay.

Any ideas? Bug in mother board?

Maybe, more likely RAM or the video card.

Recently had an ATI display similar behavior on start up.

Do you have a spare/second computer that you can set up remote access or VNC with?

If the displays go down on the Mac you can remote into it to see if the box is really sleeping or if the card shut off.

I have a couple of spare cards, if one works in your box I'll send out to you to test with.

Gimme a bit to look into it.

"Do you have a spare/second computer that you can set up remote access or VNC with? If the displays go down on the Mac you can remote into it to see if the box is really sleeping or if the card shut off."

I do (have a spare Mac I can use for this purpose). Can you explain how I perform the remote control?

I pulled half of the RAM (Two 1Gb DDR2 SDRAM) before. Will replace the installed set with these and retest.

Thanks for the Apple hand-holding.

K,

Go to System Preferences, hit Sharing, turn on Screen Sharing. Hit the Computer Setting s tab and check off VNC users may control screen with password, and enter a password.

If you want you can Allow Access for only your user account.

Close save changes

On the other computer, while in Finder, hit Command K, browse for the and select other machine and hit Share Screen.

Put in user/pass if needed and now you can control machine 1 from machine 2.

That's one of the ways I interface with my the laptop that I have hooked into one of my media centers.

VNC is great. I have one of my machines set up to be accessed from wherever.

Was on a 7 day cruise over Thanksgiving. Am at the Beach in St Thomas and started getting a barrage of automated system emails, problem with the configuration on one of our products.

Pulled up the VNC app on my iPhone, remoted into the box in my office, made some fixes and went back to my Pina Colada.

Okay. Will try that.

Just to confirm. Once I remotely access no. 1 Mac via no. 2 Mac;

If I can access no. 1 files with no. 1 monitors OFF, then the video card is suspect.

If I cannot access no. 1 with no. 1 monitors OFF, then it's not the video card.

If I cannot access no. 1 with no. 1 monitors OFF and computer frozen, then ............

Those assumptions okay thus far?

Have Porsche stuff to attend to. Will attempt this later. Thanks. Just increased my Mac IQ by alot.

When you remote in you will get #1's dektop showing up on #2's screen.

If 1 is asleep then it will wake up and displays should light up.

If you get in and the displays don't light up suspect video card.

Ok. Thanks for the details.
