This is less of a PC building question and more of a hardware troubleshooting question, but it could take buying new components to fix, so I may as well ask here.
I have a desktop that I built for myself around four years ago. A year after I built it, I moved to Japan, and left the desktop behind. It stayed in a closet for two and a half years until I returned and set it up again. And ever since then, it's been having problems I'm fairly certain it didn't have before. Cleaning the case out with compressed air seems to have helped, but not solved the problem.
Symptoms:
- Lengthy system and program boot times.
- Lengthy shutdown times for system, as well as individual programs. More pronounced when multitasking.
- Video games can hitch up for seconds at a time when loading or streaming new data. This occurred when loading or entering new spaces in Wolfenstein during long play sessions, or just about constantly when moving around the base in MGS5: Ground Zeroes.
- When downloading games from Steam, the download will sometimes pause (0.0 kb/s) for long periods of time while saying, "Busy reading from disk."
This problem doesn't seem to significantly impact system performance otherwise, and I can play most current games well enough once they're loaded. It also seems to happen independent of system temperature, though I'm not 100% sure of this.
What components might be causing this problem? Is it the hard drive? Is it because I only have 4 GB of DDR3 RAM? I'm not sure exactly how to evaluate it.
