Kernal-Power Error

So, I just got back from a trip this weekend to the west coast and when I tried to turn on my computer, it would boot up fine, but after a while, it would crash, dump, and reboot. This has happened 4 times in a row since I got back not that long ago. It's a kernal-power error in the event viewer log (Event ID: 41 Task: 63). No clue as to what could be causing it, but I might have a hunch. First, whenever I start running Ventrillo, the crashes happen soon after. Most likely it is causing the kernal-power to happen. Secondly, I just got my nVidia card back after the fan was faulty and had to be replaced. This might be a problem, but I'm not sure. Lastly, when I was moving back from college, I took a can of compressed air and cleaned out all the dust and dirt that had gathered in the computer, trying to be careful and not damage anything. Regardless, I had been home from college for a week after I had cleaned out the dust and was working off my integrated graphics card. I don't recall it crashing then. I have reinstalled the nVidia card and had no problems for a while until the day before I left. My computer crashed once then, for the same reason...kernal-power. Right now, I did an sfc /scannow in cmd and am waiting for the results. Any ideas on what could be causing the problem. Is the graphics card the most likely source of the problem? Any help would be great. Most my specs should be in the specs area with a few changed things.

As soon as my computer reboots, I'll try to get that for you. The sfc /scannow completed and has repaired any files that needed it. Let me get the log once I've rebooted.

Ok. Attached the latest .dmp file in zip format. Hope it helps.

It looks like the problem may have been fixed with the scan and fixes. Still, could just be temporary. Any ideas?

That's the latest driver. It's a long story, but here's how it went. I got back home and had to hook up to the wireless network. I couldn't find the cd to install the driver. So after long and arduous tinkering, downloading, and work-arounds, I got the router to finally work. But I will say that the computer has been running fine since the sfc/ scannow. Perhaps there was a bad file in the driver and it got fixed in the process. I'll let you know if my comp crashes anymore. The router has been working fine for the most part and I'll look to that as a solution if my computer crashes again next time. Thanks for the help.

Alright...it crashed again. Any links you can give me and advice on how to reinstall my router?
