Windows 7 BSOD (I'm not great with computers)

[Selvaria]

Hello, I just received two BSODs this afternoon, both times had different errors. First was Pool_header, the second was Pool_caller. I don't know much about computers, but I am capable of figuring out how to fix things. Here is my PC:

Newegg.com - iBUYPOWER Gamer Extreme 560D3 Desktop PC Phenom II X6 1100T(3.3GHz) 8GB DDR3 1TB HDD Capacity NVIDIA GeForce GTX 560 1GB Windows 7 Home Premium 64-Bit

Here are the dump files (I hope), and thank you in advance for any help you can give.

Edit: Right before the first BSOD (I was playing a game on steam), I heard the sound that windows make when you unplug a USB device. When I opened steam after I rebooted, I heard the sound again, but it happened about 4 times. The second BSOD didn't occur until after I closed steam and was browsing BSOD topics.
