Gem,
Your problem is hardware.
Since you said that you had to remove a memory stick to install, then you should start by:
1. going to the gigabyte site and making sure that your memory is correct and compatible.
2. testing your memory with Memtest86+
RAM - Test with Memtest86+
Memtest86+ - Advanced Memory Diagnostic Tool
With all of the problems you have had, you should look into getting a low-end Dell, HP or Toshiba computer.
