make the live knoppix cd  ftp://ftp.gwdg.de/pub/linux/knoppix/KNOPPIX_V6.7.0CD-2011-08-01-EN.iso  

boot from it and post the minidump  found in windows\minidumps

you can copy it to usb stick or drive

it looks like : bad ram, or a bad ram controller to me (= bad mobo)
if the Knoppix cd runs, that will confirm the hardware is ok

1GB is not enough for Win 7. Increase the RAM to 4GB, check if your hardware supports it also. Reinstall the OS again, and don't forget to put the good AV. Like Mcafee or Symantec

I would service the CPU cooler. It might be as simple as using a can of compressed air and blow the air back through the exhaust vent.
After doing that make sure the fan still works. If the vent was clogged it is possible for a chunk of debris to jam the fan.

the dump points to IMAGE_NAME:  ntkrnlmp.exe    and    PROCESS_NAME:  svchost.exe

unfortunately - that can be caused by almost anything
you can try updating the OS - use windows update  - if that is possible
other wise, do a system repair : http://www.sevenforums.com/tutorials/3413-repair-install.html
