Windows 7: BSOD playing any game, error 0x00000101

Alright, I ran the CPU benchmark. I didn't have any errors, and my CPU seems to be very healthy judging by the times, compared to other CPU's of the same kind.
How would you like me to run FurMark? It renders without lagging at all.

EDIT: Thanks for those details, even though I don't know what they mean.
I'll ask a friend if he can swap parts with me, but that will be a while. I'll check my BIOS now.
EDIT2:

Attention! Test, test. One two. Can everyone hear me?

Well I can't hear you. I updated my BIOS to the latest version provided by ACER. After a little bit of fiddling around, my network drivers were working again. But my audio drivers fail to install, as they fail to recognize plugged in audio devices. I did install Realtek HD Audio, which tells me there is nothing plugged in.

I've got two main audio devices;

• One cable going out of the green hole to my the red and white holes of my hi-fi system.
• One headset plugged into an USB (2.0)

Removing and replugging them doesn't do anything.

Device Manager finds;

• Realtek High Definition Audio
• USB Multi-Channel Audio Device

Is there any way to find them? Thank you.
