Can't figure out why my PC suddenly started not being able to handle multiple tasks without performance lag RRS feed

  • Question

  • Ok so about a week ago after no changes to my system or new software my PC started to not be able to handle multiple processes it had no trouble with before. I have a dual monitor set up and frequently play something like Netflix or Winamp on one screen while playing Video games on the other. I never had any lag or performance issues to speak of. I am stumped on what the issue could be. I am by no means excellent with computers, but I'm not a novice either. I simply am not sure where to start in deciphering my problem. When I run one thing at a time like Winamp I experience no issues, however if I try to play a game by itself I do experience performance issues where I didn't before. I assume this is because a game takes more from my machine than a media player. Any suggestions on how to begin figuring this out would be appreciated. 

    Here are two screens from my Task Manager while I am not running anything. Below the images I will post the first part of my DX Diag. Let me know if anyone needs to see anymore of it as I know most of it is not needed.

    Thanks to anyone that can help.

  • Do you have any temperature monitoring programs in place (I didn't notice anything in Task Manager)? If the case hasn't been cleaned out in a while, it might be time to check that. Look for dust on any of the fans and heatsinks, and the components. Heat build-up will cause the CPU (and the GPU) to throttle back to keep themselves from overheating.

    Have you done a malware scan lately? Could be some nasty running in the background that doesn't show in task manager.

    If the problem persists, you can start here to help determine the possible cause:

  • Well now I feel slightly silly. I cleaned out the machine and it seems to be working fine. I just cleaned it a month or so ago and generally clean it every couple months. I just moved to a new place and have the space it is in is smaller (with pets) so maybe that would explain why the dust collected quicker than usual. I think I will just bump up my cleaning schedule and if I have performance issues beyond that I will try these other methods. Thank you for your help!

  • You're welcome! I'm glad it was something simple (that "clean boot" procedure can certainly take some time).

    I have a long-hair cat, and I have to vacuum mine out at least once a month, and that's with the mini-tower on a stand about 18" off the floor. It's amazing how much an "indoor only" cat can shed. If I could transplant it, I wouldn't have to wear a hat outdoors :-)
