What will you do when your computer suddenly Hangs up/Lag?

it depends when this happens and whether i will loose data on doing this or not. it also depends how long the hand will remain. i will always wait for the hang to en before restarting the PC

I start by closing any unwanted programs I don't need running this includes shutting down any background programs as well. This frees up ram which helps with performance. I check my router and internet settings to ensure i'm receiving the best signal. I perform a system clean up and promptly restart, and e walk away for a bit. This prevents freezing quite as often and helps my system working its best.

I generally just turn my computer off until I calm down. And then start from where I left off. Recently my computer had a complete freak out. And crashed like every 10-15 minutes, sometimes not even that... It taught me to save it whenever it crossed my mind though!

i will do that, shut down the computer. before that i usually change the value on the register editor because if we change the value can make increase performance and your computer relax.

I just shut off the computer and start over. It makes me so mad because mine does it a lot. Some real smart person put the fan on the bottom of my laptop so it over heats and freezes up.

I would try using Ctrl+Alt+Del first to see if I can end the task I'm performing to get the computer back to working. If it doesn't work, then I would just power off my computer directly and restart the computer.

It is really annoying when this happens I usually do the same thing, I save anything important that I am occupied with or working on before shutting the computer down for a while, passing the time by doing something else, before returning to it later.
