I came into a used laptop from a family member, and decided to upgrade it to Windows 10. Everything was fine for a little while, but recently I noticed the file explorer and the start menu not opening. It was strange, so I took a look in the task manager, and discovered that the drive usage was pinned at 99 percent, occasionally jumping to 100 for a few seconds. There seemed to be no cause for it, so I tried disabling a couple bits of software from the advice on online forums. No luck. But, it just so happened I had a drive from an old laptop, which also ran Windows 10 (had previously run XP, but I installed the tech preview on it and it ran really well, so I kept it). I swapped the drive out and found the problem resolved, so I decided to just keep that drive in there. However, just yesterday, I started my computer and ran into a major slow down. Strange, so I hopped into the task manager, and the drive was pinned, this time dipping no lower than 100%.
Now, I don't use the computer that often because it has some overheating issues. I.E., the geniuses that made it threw in an i7 and mobile GPU, but decided that one dinky little fan was plenty. So, the computer, in the past, would crash every hour or so from overheating and I could easily get the CPU to 100 degrees (Celsius) when running a stress test. I'm thinking that the computer's tendency to run so warm might be the issue.
If anyone has any insight, please let me know.
