computer shuts off while working on adobe programs....need some help

[shutterleftopen]

hey,

i have just recently upgraded some hardware on my pc. today i purchased a new processor and video card. i'm a graphic designer/photographer and had problems editing large files in photoshop so i decided it was time for an upgrade. after installing everything i changed my BIOS settings to allowing all 3/4 processors enabled then installing the drivers for my video card.

i went into photoshop to edit some big files and once i started saving all of them the computer shut off. turned it back on to try it again and as soon as i started doing heavy work it shut off again. my concern is that since upgrading my hardware that i now don't have a large enough power supply.

my set-up:

nvidia quadro fx 580 (the new video card i purchased)

intel core 2 quad q8400 (the new processor i purchased. was an intel core 2 duo)

nvidia nforce 750i sli ftw motherboard

6g of ram

xigma tek 650w power supply

i'm not sure what the problem is but man is it frustrating. any help or input at all would be greatly appreciated. i'm just trying to finally have a system that doesn't give me problems.

thanks.

Check your CPU temperatures - did you remove the motherboard from the case to install the new processor? If not, I'm betting the heatsink is not completely snapped down.

The FX 580 doesn't need much of a power supply - specs say it only uses 40 watts.

thanks for the reply man.

i didn't take off the motherboard. but i'm almost positive i got the fan over the cpu on all the way.

i downloaded HWMonitor and checked my temps. it looks like just sitting here the CPU temp is around 60 degrees Celsius. i tried getting into photoshop and doing some extensive work and the temp rose to 116 degrees Celsius. i'm not sure if that's too hot for a cpu or what. could that be my problem?

Either your heatsink is not all the way attached, or you used way to much thermal paste. That should be in the throttling zone of a core 2 quad, you need to check out your heatsink immediately, and in order to do it right you need to pull the board out of the case.

[glc]

You cannot properly install an Intel heatsink without removing the board from the case. In order to put enough downpressure on the pins, the board must be directly supported on the bottom. If you are able to put enough pressure on it to seat the pins with it in the case, you will be excessively flexing the board and possibly cracking solder joints.

so is that for sure then the problem? the processor already came with thermal paste on the heatsink so i doubt that's the problem.

what should the temp be running large editing programs on an intel core 2 quad?

[glc]

No more than about 60 to 65 C.

thanks a lot. that was it. my first time taking out a motherboard and it went well. those heatsinks are a pain in the ass though. hah. but i got it. did the same large batch process in photoshop that was shutting my computer off and it did the entire process without going over 66 C so i'm definitely glad that fixed it.

greatly appreciated.
