BSOD after PC has been running for a while

I'm having a problem where my computer is getting a blue screen. I have noticed that the BSOD happens after the PC has been running for about 2 days. The BSOD's seem to be an error with atikmpag.sys with an error code of 0x00000116. The problem started about a month ago.It has happened all five times that I left my computer on that long in the past month.

Because my computer is a pre-built one from Dell, and I had upgraded the graphics card (at least a year ago) to a more demanding one, I replaced the stock 360W power supply that came with it. I replaced it with a more powerful, 680W one, because it seemed like the problem could be related to a lack of power supply wattage, but it didn't affect the problem at all. I have also run Memtest86+, and no errors were found.

Here are the minidump files for the five BSOD's that I have experienced:

System info:

• Windows 7 Home Premium x64
• Dell Studio XPS 435MT
• Radeon HD 5670 (Version 12.4 of the Catalyst driver)
• Intel Core i7 920 2.67 GHz
• 6GB of RAM

Let's see.

This thread at Overclock.net was started by someone using an ATI card, getting that same BSOD (error and file). People suggested multiple different theories, and one of them pointed to a driver related issue and solution that worked for some people (apparently this isn't uncommon). In the first thread however, it turned out to be a faulty card that the owner got replaced for free by the manufacturer.

So. here is what I would do. First, follow these instructions from that second link I gave you...

Try and do it in this order: [Fixes] Catalyst Drivers Error & OC & Eyefinity & General Issues

1. Uninstall Afterburner and Catalyst from manager.

2. Clean it with Atiman Uninstaller v.6.3.1 (turn off UAC to install this).

3. Install 1/25/2012 http://support.amd.com/us/gpudownload/windows/previous/12/Pages/radeon.aspx?os=Windows%20Vista%20-%2064-Bit%20Edition&rev=12.1

4. Install MSI Afterburner 2.2.0 Beta 14 Download

5. Enable "unoffcial overclocking" HOW TO: Enable UNOFFICIAL overclocking mode in MSI AfterBurner

6. Afterburner settings > enable all voltage controls.

Note: Exit Afterburner prior to editing .cfg file and ULPS.

Crossfire User- Do the following between steps 4 and 5:

Disable ULPS:

• Go to regedit (start > search programs and files > "regedit").
• In drop down menu: find file > type "enableulps".
• For ALL instances (keep pressing F3) change the "1" value to a "0".
• Reboot PC.

Edit:

Use latest Afternurner 2.2.0 Beta 15

.. and again, this seemed to work for some of the people with the same error code and system file popping up on a BSOD. If that doesn't work, look into getting the card replaced under warranty (if you can).
