The first thing I'd do is return everything to default clocks and voltages. If you've overclocked anything, reverting it back to stock is a good general troubleshooting step.

Next, uninstall and reinstall the video drivers. From ATI's website:


Quote:
1. Uninstall the current ATI Display Driver and Catalyst™ Control Center version from the System

b. For Microsoft Windows Vista® and 7®: Use the Catalyst™ Install Manager (CIM) via Programs and Features to perform an express recommended uninstall for users.


After this, download and reinstall the latest drivers.

If you still have problems, your system may be overheating. There are many temperature monitoring programs, but CPUID has an easy to use and free program in HWMonitor http://www.cpuid.com/hwmonitor.php This will allow you to monitor both the processor and video card temps. The CPU getting to hot would likely cause a random restart.

I've done all of that, I recently bought 4 new 120mm fans for the side of my case the card runs cool, the thing i've noticed is the D601 light comes up which i believe means a Power supply issue but my powersupply should be sufficient

That's probably your answer, then. Power supplies often do not go quickly or quietly. Random restarts is a common sign of a power supply that is beginning to fail.

I myself had a computer about 3 years ago that started to reset randomly. As my power supply wasn't the most reputable brand, I was fortunate enough to suspect it first. The problem cleared up after replacing the bad PSU.

If you're able, borrowing or using a spare power supply (PSU) would be the best bet, as you don't need to make any investment to make sure this is the cause of your issue. Unfortunately while a power supply can be tested, as you've seen your PSU still gives good power most of the time, it just wavers occasionally enough to where it can't provide the current required by your games.

Out of curiosity, can you provide the brand and model of the power supply?

ATM I cannot i'll find it on newegg and reply again, but what i was going to ask was could it be a memory/motherboard/cpu problem, i've been told one of those could be the issue by a friend and was curious if there was any way to test each without rma'ing them and going through the process of elimination

If you can give the brand and model name/number, or failing that, put up a picture of the PSU's specifications sticker, that would help. It sounds distinctly like a power issue.

Have you experienced the issue only in heavy 3D environments likes games and benchmarks? Complete shutdown/restarts are often the product of power supply problems, especially considering what you have already done to try diagnose the issue.

Any ideas other then a power supply issue?

Your best bet is to eliminate the PSU as the problem, by either returning it for exchange or refund if possible, or by borrowing another one to test for the same issues.

It is really hard to diagnose other problems with the most likely of variables (PSU) hasn't been eliminated. As mentioned before, random restarts in power hungry environments (while gaming) points directly at PSU issues.
