Welcome.
Wow, so many bsods! I've moved your post to its own new thread since all issues are different and must be treated as such. Let's fix them.
1) Update your bios to the newest available:
Link Removed - Invalid URL
2) Remove all USB sticks or external drives.
3) Post new crashes if/when they happen. Your motherboard may not have compatible drivers for Windows 7. Some are very old without any updates. We'll see how it goes after you've done the above.
