Freeze lag

The last couple of days I started getting this "freeze lag" when playing dota 2. The game freezes from 0.5-2 seconds or something like that, seems like it's random. Happens randomly throughout the entire game. This is NOT lag caused by bad internet, servers, etc. Looked around online and couldn't find any solutions, most people just said it's network lag etc. Anyone have any idea how to fix this? Extremely annoying, especially when it happens at the absolute worst time...

have you thought about checking whether your graphics card/processor is working properly, my second thought is that are you on a network with multiple users using the internet at once, my third and final though is that have you got enough cpu/ram to run Dota.

First two seem most likely to me but other than that nothing else I can really do without more information. Also have you tried playing a different moba because then you could find out whether it is your dota files or your computer.

I'd verify file integrity to check the files are fine. Also what's your setup? Ram and cpu?

Well my setup is this:
Graphics card: Nvidia GeForce GTX 770
Motherboard: Asus z87-deluxe
Ram: Corsair 16gb ddr3
Processor: Intel core i7 4770k 3.5 ghz
cooler: Noctua nh-d14
256gb ssd
2tb hdd
OS: Windows 7 Ultimate 64-bit

Steam is on the ssd and dota is on the hdd, does that make any difference? Only ones using the internet is me and my girlfriend, but she only uses it for facebook/netflix etc and it should be more then good enough for the 2 of us. I haven't tried playing any other mobas but there are no problems with any other games I have. Also fairly new computer since I bought the parts like 6 months ago, haven't had any problems with it so far.

Do you know if it happens to other players and do you get the red disconnect message in the top right corner?

No disconnect message, just a small screen freeze. Looked around a little and saw some people who I think had the same issue, but there weren't really any answers that helped.

From what you've said, the only thing that would cause this to me is the possibility of corrupt or screwed over (technical term) file.
I have had an issue with Dota before when it wouldn't give me in-game community. I re-installed and it worked fine again so that is my only suggestion if you can't find an answer.

I'm having this exact issue. I've been looking around for a while, but I've found near-to-no queries about the problem. My parts are fairly new (about a year old), and I've been playing dota since I got them. No amount of re-installs or updates seem to fix it.
