A useful description of bsod found
here
It is very difficult to troubleshoot from here, but I think the key to solving it lies in the changes you have made....which is your fresh OS install.
You may be missing some drivers that you had present when running previously, such as gfx, chipset or audio.
My personal experiences of bsods have been hardware related, usually from overclocking a system too far, or faulty ram.
If ram is faulty why no probs before reinstall of OS? O_o
Is a difficult one.....
Have you made any hardware changes as well?
