So I am going to explain this in a way where even if you don't have any knowledge of Minecraft you'll be able to understand the issue. So this all started when I was playing a customized modpack with 200+ mods (Big Modpack) and I accadentally used //regen from WorldEdit on a massive area (Extremely CPU intensive) which caused me to have to restart my game. When I did this I realized that I had destroyed my house in the process so I went back and restored a world back up. Everything continued to be fine for a while until I used WorldEdit again later on and it just caused everything to stop like my keyboard and mouse stopped working and lighting up, my headphones made the disconnect sound and my sister (who was playing on my LAN server) got disconnected) I went and restarted my computer to find the world had been corrupted so again I used a world backup and continued for a while until this happened again and now it is becoming more frequent and it has also started to happen outside of minecraft as well. Please help I am concerned about my computer haha.

Check all fans are running and try to clean out any dust.
Start by testing your memory. You can google for "memtest86+". Download the iso and burn a bootable CD. Boot from the CD and allow it to have multiple passes on your RAM.
If your whole computer is crashing, then it could happen in memtest as well as Windows. If memtest finds errors you will see a report. If the PC crashes while it is running, the issue is somewhere else.
The graphics card is also relatively easy to test by removing it and using the onboard graphics. Run some sort of stress test on the computer, any CPU benchmark will do.
How much RAM is installed?
Are you using a 32-bit or 64-bit version of Windows?
If you open task manager while running Minecraft, what is the figure for "Available memory" on the performance tab and memory (private working set) for minecraft on the processes tab?
 


You said you can get it working by restoring a backup, you should be able to check RAM usage.
Minecraft in the past used a 32-bit version of Java so it would crash if using more than about 1.6 GB of memory.
If it is still a 32-bit process, it should have a "* 32" in the Image name in task manager.
They may also offer a 32-bit or 64-bit version for download, in which case you should use the 64-bit version.
