I was in the middle of playing a game when it suddenly crashed, and I noticed that all my other applications were struggling too. When I checked the Task Manager, it showed my disk usage at 100%, but there wasn't much showing in terms of usage—only about 1 GB. I'm wondering if this might be caused by a virus or if there's a fix for this issue.

In Task Manager, you can click on the Resource Monitor link to see exactly which processes are accessing the disk. That might give you a clearer picture of what’s going on.
You might need to look at your RAM situation. If you’re low on memory, when the game crashed, it could have pushed all other processes into the swap file on your disk, causing the drive to work overtime. Increasing your RAM might help.
If you're running on a traditional HDD, this could be pretty normal behavior for Windows. Upgrading to an SSD can make a big difference, as modern Windows versions generally perform better on SSDs.
Try opening the Task Manager as an admin and see if anything looks off. Sometimes, Windows runs background processes like search indexing, which can spike disk usage for no apparent reason.
Have you checked if your hard drive might be failing? It could be worth looking up some steps to test its health. If it's failing, that could definitely cause those disk usage spikes.
