HeatoftheNight,
This time as soon you have installed Win 7 again AND
immediately install Microsoft Security Essentials (MSE) Link in my sig,
then
Make a system image backup to an external drive.
Use the Win 7 Backup and Restore for this.

How to Create a System Image Backup in Windows 7
===========================================
Do Not install any other AV in place of MSE until we are a little further along.
It is imperative that you have a solid system first!
Now you have installed Win 7.
You have installed MSE.
Now install ALL critical updates.
Install ALL important updates.
Install ALL optional updates.
Don't try to be smarter than Microsoft. Don't say wll I don't need that. Just do it. Install each and every update.
Now after all of this, once again do a System Image Backup.
Now and only now, can you start to install some of your favorite programs.
The idea is that you don't want to reinvent the wheel again. You want a solid system as a return point.
Create a system restore point VOR each install of a piece of software.

If after using your system for a couple of days, you find the system to be solid and stable, then make another system image backup.
