Weird Memory Usage Spike

[cleverpun]

I was using my computer as normal; watching youtube via firefox, and then the video suddenly started skipping and stuttering. My computer became unresponsive, and I eventually had to restart it then force a shutdown. Task manager looked something like this;

 

 

Any idea what could have caused it? I'd like to avoid such problems in the future. My computer appears to be working normally now, and the only notification it gave me on startup was a note that updates couldn't install properly. Could it have been a glitch with the update installer?

 

Thanks in advance for any advice

Might just be a freak event, if it happens again, you should look into it further

Mine does that aswell, it will come inches close to crashing and force me to shutdown, though mine is win7.

Iirc if you power off or shut off your router during an update it can corrupt some files and when the ram can't handle it, it will stutter

tfw did the same to me earlier today during a 14 key trade nice

I see you have AVG

AVG is an asshole and likes to cause memory leaks or something after scanning.

the only way to stop it is to disable auto scans and manually starting them when you feel like restarting

^can confirm.

 

AVG killed my comp until I finally uninstalled it in favour of avast

Get process explorer first, it's much better than stock tskmgr. Second, the "system" is a bunch of processes and each of those can cause bad things. By your description it could be interrupts. I had a problem with them and it eventually stopped. I don't remember how or why though.

 

So get procexp, find what process is causing it and then google.

After using process explorer, removing AVG in favor of Avast (even though I don't think that was the issue) and doing a bunch of googling, I think the problem is SuperFetch (whatever that is) there's lots of topics about it, but the problem doesn't seem to be clear in a lot of cases.

 

If anyone is interested/has the same issue, here is the post I used https://social.technet.microsoft.com/Forums/windows/en-US/6d0b13bb-78b6-4cd9-ab98-9ac256444c3c/build-10240-bug-system-process-uses-too-much-memory-because-of-superfetch-feature?forum=WinPreview2014Feedback

 

We'll see if that fixes it or not

SuperFetch was something implemented I think back in the XP era, and it was something that checked which programs were frequently used, and set up the memory so that these applications could start up faster. Sounds good on paper, but it was a disaster. Memory leaks and high RAM usage due to it being enabled, and next to no improvements in application launch speed whatsoever.

 

Best to leave it off if at all possible.
