Frequent BSOD after upgrading CPU.

Hi there, I recently upgraded to an AMD Phenom II x6 1090T from an Athlon x4.

I first booted the computer using my original W7 install, but after frequent blue screens, I decided to format, during installation of windows 7 I got the BSOD 3 times, but on the fourth, it installed fine. But I still get the BSOD's.

I'm at work at present and unable to attach the zip file.

My system specs are:
Amd phenom II x6 1090T
Foxconn a7da-s 3.0 motherboard
Radeon 5770 1GB
8GB g.skill DDR3 1333mhz RAM
and a cheap 700w power supply.


Any help will be appreciated. Many thanks!

Also, the frequency of the crashes vary from a few minutes to a few hours. I will upload the dump files tonight. Many thanks.

The file should be attached to this post.

Many thanks again :)
