After reading some articles, I think one of my RAM bricks are corrupted, but I want a complete answer from you guys.
So here's my story:
My PC lies inside my desk on a shelf. Yesterday I hit my desk with my office chair so it bumped my PC and it instantly shut down. After restarting, the screen was completely black (even the indicator light on my screen went orange, indicating it wasn't connected to anything), so I had to force the computer off once again. The second time I started, it worked and I recovered my PC to a past point (Windows Recovery) and thought everything was fine.
But now multiple issues occurs, based on things not starting and working as they are intended. For instance:
League of Legends wont start after I hit "Play" on the launcher, but it shows under "Processes" at Task Manager.
I can't join or do anything on Battlelog except refreshing the server list.
I can't install any programs, it says the source file is corrupted.
But Steam works, and I can play Skyrim no problem. (Except it crashes kinda often).
They also are likely to take damage from violent movement as mentioned.
The "arm" that reads/writes data on it is a few nanometers above the disk surface so a bump can easily move it that few nanometer distance and cause it to physically touch the disk, creating problems potentially.
Sorry to hear your RAM got screwed up, at least it is cheap.
