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.

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