Okay, I'm back, but not with a new video card. I had someone else take a look at the computer and he noticed that one of the drivers for the motherboard was not working, so he installed the driver and told me to get back to him in a few days about whether or not it blue screens again.
Meanwhile, I found out that the guy I first took my computer to changed the power supply in my computer for some reason. My power supply was originally 600 watts and now it is 400 watts. The new computer guy seemed to think this made no sense and thought that also could play a role in the blue screens.
So after updating the motherboard drivers, it did blue screen again. I was wondering if any of you could take a look at the last two most recent minidumps to see if anything about them looks different from past ones or if anything stands out?
Also, for what it is worth, the first of these BSODs wasn't an actual blue screen, it was this dark red-ish color with bright red text...
