W520 Freezes and makes loud buzzing sound

This happens every once in a while and I cannot figure out what is causing it. The laptop freezes and buzzes and forces me to shut it down via the power button. 


Can anyone shed some light on what might be going on? The past two times it has happened it was when I was using Chrome.

Re: W520 Freezes and makes loud buzzing sound

Hi, zackh123


I would recommend checking the logs in Event Viewer, which can be found under Control Panel ► Administrative Tools. Once in Event Viewer, open the folder Windows Logs and check out the System logs. Try going back to the last time this occurred and check for any errors or warnings that may lead to the system freezing like this.


Also, what is your operating system? And from where does the buzzing sound seem to come from?


Thanks in advance,

Re: W520 Freezes and makes loud buzzing sound

I did do that and it's hard to read the logs. It said something about chrome but I'm not sure if it was when the problem happened or directly after I booted the computer up again and chrome crashed. The buzzing sound seemed to be coming out of the speakers or not just one part of the computer. To the ear, the HD seems to be running well too.

I updated the BIOS and both video card and it has not happened again, but I will stay in touch.
