when you say it gets a fresh start, do you mean the PC shows the BSOD and then reboots? – Dave Jul 20 '12 at 8:40

I recommend the following troubleshooting to fix the problem:

  1. Run Windows Updates.

  2. Check system BIOS version (update to the latest version if necessary)

  3. Update the Chipset, Wireless and Video Card Driver.

  4. Run PC Diagnostics with Hiren's Boot CD or Ultimate Boot CD

  5. For the BSOD codes, look them up on: MSDN Bugs Check Code reference

  6. Perform a clean boot:

Click on "Start" when your Windows 7 loads. Type "msconfig" on the search bar and hit "Enter". Go to the "Startup" tab and disable all the applications listed. Then go to the "Services" tab and check mark the "Hide all Microsoft Service". Click on "Disable all Services". Click on Apply and restart the computer.

Test the computer and if no BSOD is shown, start re-enabling one by one each Service and each Startup application until you discover which one is causing the BSOD.

Extra help here.

Follow this guide you will find a solution. Remember to test the computer after any change if no BSOD is shown.
