Well, based on your testing, Im going to guess that the Mobo is faulty. I would send it back for replacement

Have you tried updating the motherboard BIOS with the latest version?

No problem, sorry I couldn't help more, maybe someone else might post with another suggestion. Do post when you figure it out though

The temps you gave me don't indicate that, now if it had gotten up into the high 80's- low 90's, then I would say that it was that for sure. You can try adding new thermal paste, but no guarantee's its going to do much of anything

I'm thinking its the PSU. its already an off brand, coupled with it being so old, and being so close to how much the system could potentially draw, it wouldn't surprise me if the capacitors have degraded to the point to where the PSU can no longer output enough power. Do you have a PSU you can take out of another system and test it?

Thats perfectly fine, so I think we can rule out temps as being any sort of cause. if the computer is at idle, does it just sit there, or will it eventually go black?

hmm, what are the temps on the GPU? do they spike right before it locks up?

Sounds like an entire system lockup, sounds like the PSU is either not delivering enough power, or a cable has come loose. I would check all power connectors on all hardware, to make sure their seated correctly.

So by black, do you mean the system shuts down, or is it just the video, ex. if you were to play music then run a test that makes it crash, would the music keep playing, or is the whole system locking up?

Could be power delivery issues, what brand PSU is it, and how old is it?

My bad, I read LCD from the line above back light and decided that LCD is a backlight technology. However, if you believe dell, their monitor is a full LED monitor, unlike the LCD Acer. That's what i really was trying to say. And the two technology's do produce a different color temperature, but you should be able to adjust them and get them close to each other.

Another thing to remember is the Dell is using LED backlight, while the Acer is a LCD backlight. The LED will always seem much "cooler" then LCD

You can just lower the multiplier, but I believe you can only lower it so far.

Thats what I thought. I dont do much with personal computers anymore in terms of hardware, my bread and butter is server hardware. The hospital I work at runs blades, and I know if a blade tries to draw to much the server will throttle down the blade and move work around the different servers to balance out loads and stress on the PSU'S

Awesome, good to know. My sig is off a little, I do have a few more video cards in here for work, but I guess ill just grab a power meter from Amazon and check it off. Do you know what would happen if it was to try and draw more then the PSU could handle? It should just shut down right?
