What should i do when PC hang?

Answer 1

By pressing Ctrl-Alt-Delete, the most famous key combination and choosing Log Off from the menu that appears. This only works with Windows 7 and Windows Vista. For Windows XP, pressing Ctrl-Alt-Delete will bring up the Task Manager. If that's your case, go to the Shut Down menu in the Task Manager.

Answer 2

Frequent freezing or navigation failures may be a warning sign that your computer is running low on memory or space on the hard drive.

There are various computer programs that can help solve your computer hanging problem, or you can take it to a qualified computer technician.

You can try reducing the number of windows or tabs you have open and see if it alleviates the issue. You can reduce the number of programs you run at the same time. Some programs present a heavier load on the system and may require more resources causing the system to hang while it tries to get the resources. This could be happening with newer games. Check your Task Manager and see if anything is running that shouldn't or if anything is using more resources than expected.

• You may have a virus. Run some antivirus programs (malwarebytes, Microsoft Security Essentials) and see what they find.
• You may be running out of disk space. Check your disk space.
• You may not have enough swap space allocated and you are causing the system to thrash. Check your disk active light and see if it is on all the time.
• Check your logs for hardware error messages. Your hard drive may be dying.
• You may just have an older system that can't handle everything you are trying to do.
• Run something like "ccleaner" to remove temporary and cache files.
• Run a disk defragmentaion program.

Answer 3

If there is no response on pressing Ctrl + Alt + Del, I would keep pressing the power switch down until the laptop switches off, then press the power switch once to begin restarting the laptop again.

Answer 4

When your PC hang then restart your PC through restart key or combination of Ctrl+alt+delete key.
