Random BSODs, freezes, and restarts with a pixelated screen.

[ReallyFat]

Hi there. For the past week, I've been getting some random BSODs, some freezes, and sometimes just a random restart. there is a flash of a pixelated screen, and then it just restarts. This computer is nigh on two years old, and has showed no sign whatsoever of slowness or any malfunction. Yet for the past week or so, it's been randomly crashing and getting restarted. Specs
-Intel Pentium Dual Core processor. 3 GHz.
-ATI Radeon graphic card. 1 GB.
-2GB RAM.
-320 GB storage space.
-HP Pavilion CPU.
-Desktop PC

I would upload the dump files, but honestly, it crashes by the time i press the copy button. i am attempting to get them using the homegroup from this computer.
anyway, i would really appreciate some help.

EDIT: I managed to pull the dump files out from the homegroup. here they are.

The above crash is related to a USB device. What devices do you have plugged into your USB ports?

• Start with http://www.sevenforums.com/tutorials/165554-usb-driver-general-fix-problems.html to resolve the USB issues. Also, USB ports can sometimes enter a safe power state to protect the system from power surges due to USB devices. To reset the USB ports to a nominal power state:
  
  1. Shut down and turn off the computer.
  2. Unplug the computer from the wall or surge protector (then remove the battery if it is a laptop).
  3. "Remove the computer from any port replicator or docking station, disconnect
     cables to printers or devices such as external monitors, USB memory sticks or SD cards, headset or external speakers, mouse or auxiliary keyboard, turn off WIFI and Bluetooth wireless devices." (Use Hard Reset to Resolve Hardware and Software Issues HP Pavilion dv5000 Notebook PC series - HP Customer Care (United States - English))
  4. Hold down the power button for 30 seconds. This closes the circuit and ensures all
     power from components is drained to clear the software connections between the BIOS
     and hardware and clear any corruption in the temporary memory.
  5. (If it is a laptop, plug the battery back into the laptop and then) Plug the computer back into the wall. Do not reconnect any unnecessary peripherals; monitor, keyboard,
     and mouse should suffice and be the only peripherals reconnected.
  6. Turn it on to reinitialize the software connections between the BIOS and hardware

in my USB ports? A Genius i608X graphic tablet, one wireless keyboard and mouse dongle (i only use the keyboard, mouse is off and stored elswhere). then i have speakers, which don't use a usb port. and i think thats pretty much it

Alright, just go through the steps laid out in my previous post. Sounds like you do not have any unnecessary devices plugged in at the moment, so hopefully just the steps will resolve the problems.
