Okay, here's the deal. The dmps do not tell the cause straight out. We will have to guess at it.
I cannot say that AVG is the cause, but I do know AVG causes its fair share of BSODs. I would suggest removing it completely and then installing
Microsoft Security Essentials instead. Use this removal tool:

AVG is not pointed to as a cause, but even if it's not, you may be happier with the performance of MSE.
Here are the summaries for your bugchecks 1A and 3B, respectively. Both taken from here:
BSOD Index Quote:
Usual causes: Device
driver, memory, kernel
Usual causes: System service, Device driver, graphics driver, ?memory
As you can see, memory and device driver are suspects.
Download a copy of
Memtest86 and burn the ISO to a CD using
Iso Recorder. Boot from the CD, and leave it running for at least 5 passes.
To test for bad
drivers, please enable driver verifier:
Using Driver Verifier to identify issues with Drivers
Please UPDATE your chipset drivers on the motherboard manufacturer or computer manufacturer's site:
