Why rendering an animated scene all of a sudden freezes computer?

Question

hopefully someone can help me with this question. As of about 2 weeks ago (where before everything was fine and smooth) Blender freezes my entire computer when i try to render a pretty simple scene of the camera panning through a field. Before, the scene rendered just fine, but i had to delete the png images because i rendered them into the wrong folder. But when i render the scene now, it will only render a handful of images before completely freezing my pc causing me to have to do a hard reset. Also I am rendering using Blender Internal render. Here are my PC specs: OS- Windows 10 Pro Processor- AMD Ryzen 7 (8 CP) Graphics- NVIDIA GeForce GTX 1600 6GB Blender 2.79 If there's anything else you need, let me know.
