Computer freezes when opening large files
Your computer doesn't have enough memory to hold the file. It's using the hard drive as backup memory, which is much slower. Close all other programs before opening big files. This fixes the freezing.
When your computer freezes opening large files, you don't have enough RAM. The file is too big to fit in fast memory, so Windows spills it into slow hard drive storage. Close other programs and the freeze disappears.
Risk: Medium
⏱ 10-20 minutes

⚡ Before you start
- ✓Close all other programs before opening the large file — every open program uses RAM

Skip, I just want a technicianCommon mistakes to avoid
- Forcing a shutdown during file loading — wait at least 5 minutes before giving up because interrupting can corrupt the file
- Opening multiple large files at once on a computer with 4GB or 8GB of RAM
- Assuming the computer is broken — this is a capacity problem, not a hardware failure
Signs you need professional help
- If your computer has 4GB or 8GB of RAM and large files are a regular part of your work. If a file takes longer than 10 minutes to load and never completes. If you want a RAM upgrade assessment and help choosing the right type.
