Windows 7: BSOD after I reformatted.

I have reformatted my computer and I still get Blue screens at different times and there are not during the same program.
I have win 7 64 bit
Hardware is a couple years old except the graphics card which is 4 months old.
I reinstalled the os last week.
I have the full retail version of the os.

Thanks for the help in advance.

Avast can be a contributing cause of BSOD'S . Please remove and replace with Microsoft Security Essentials AT LEAST TO TEST

Microsoft Security Essentials - Free Antivirus for Windows

I uninstalled it. Now I was getting a blue screen before I had avast installed and before I installed a fresh copy on Windows 7.

Let us know if you are still having the problem

Will do thanks.
