is my system under powered?

I'm trying to get some help. We need someone from the BSOD squad who can read dump files. You should look at this thread about posting BSOD's, they will probably want this info too.

Hello,

Before going off to buy a new PSU, you might try removing one of the video cards. That will significantly decrease the power load on the PSU, and may confirm or cast doubt upon the theory.

I'd suspect you are seeing a hardware problem, though there are a few things that stand out to me. First off, SP1 should be installed. See here: Learn how to install Windows 7 Service Pack 1 (SP1)

The 2005 version of ASACPI.SYS is running on your system, which has known issues with the latest versions of Windows. You might install the ATK0110 driver from the Utilities section here: ASUSTeK Computer Inc. -Support- Drivers and Download M4A78T-E

PC Tools has also had some serious trouble with Windows. While I'm not against the idea of you removing the program (I dislike it strongly myself!), I don't see the need in asking you to do so until Driver Verifier blames it. Try running that tool as described here: Driver Verifier - Enable and Disable

Finally, run each of the three Prime95 tests: https://www.sevenforums.com/tutorials...t-prime95.html

After all that, also check for the latest BIOS. I had a similar problem.

Not much we can do without the results of the suggestions that have been given...

Did you select upgrade or setup while trying to download Prime-95? Attachment 166350

It's likely the same BSOD as you haven't reported being successful with any attempt to rectify the situation.
