Extreme lagging and crashing daily
So I got this desktop on 13 july 2018 but I started using it 25 December 2018, it handled games pretty good no lag, but recently I've been experiencing major lag problems, for example opening Google chrome makes my computer lag out a lot, Sometimes even crash. On my computer every single time I go onto YouTube it plays the video very slow and choppy and crashed.
Is this a software problem?
Is this a hardware problem?
Type of windows:
Windows 7 professional.
I am not sure if I should fix it or get a new pc.
Is this a good question?
