Hi Everyone,

I am writing this to ask my fellow summoners for help. Sometimes when playing League of Legends (I estimate once every 20 games), my computer will simply lock up. I can't alt-tab, I can't alt-F4, I can't Ctrl-Alt-Del, I can't even press the numlock key and have the light toggle on my keyboard. Basically, whatever the problem is, it's blocking everything. My first thought is that I have some kind of hardware issue, but I have not had this freeze happening while doing anything other than playing League of Legends.

Does anyone else experience this? I haven't observed a pattern yet to what causes this. It's not any specific action that I do, or not that I can tell. One minute everything is fine, the next my computer is completely frozen and the only thing I can do to recover is a hard reset. Thank god for the Reconnect feature, but sometimes I can't reconnect before my team decides to surrender.

Any help at all is greatly appreciated.

NVIDIA GeForce GTX 580

I have a number of theories, including:
- Maybe the northbridge overheating (but why then not in other games?) CPU and GPU are both liquid cooled, temps are fine.
- Hard drive issue. But why not in other games? I've completely uninstalled and then reinstalled LoL. I also tried repair feature one time. I still have the issue.
- I'm on Skype at the same time. Is there a known issue with Skype?
- Is there a known issue with Razer mice? I'm using a Razer Abyssus.

I had a similar issue with launching Mechwarrior Online a few weeks ago. Every single time I'd launch the game, it'd load up and then my computer would completely freeze, requiring a hard reset. However, once I dug into the nuts and bolts of the issue, I found that the game was freezing due to my GPU freezing and being unable to recover.

I would recommend updating your graphics card drivers once and trying, that fixed my issue.

Also, related question: Are you running a solid state hard drive as your OS or gaming HD?

Hi Morgageddon,

Thanks so much for your reply!

I have installed the OS on a solid state drive. League of Legends is on a platter-based (spinning) magnetic hard drive. Is there a known issue with SSD and LoL?

I have updated my graphic card drivers multiple times, and each time I've been hopeful. I still experience the issue now and then.

I looked in the Windows logs by the way and I don't see anything indicating a GPU freeze. Not saying that's not the cause, because in my limited experience hard freezes like this are almost always hardware, with the GPU as a prime suspect. Still, I don't understand why the problem doesn't appear in other games for me. Maybe it can happen, but simply hasn't happened in another game yet.

Vichar, yes there is for the SSD/platter with LoL.
I had a 90 gig SSD running a Sandforce control chip.
When I would be playing LoL, sometimes the SSD would FREEZE and windows itself would crash for anywhere from 30 seconds to two minutes at a time, IF it recovered. If it didn't, I had to reset the computer.

What model SSD are you using? Because to me, it sounds a lot like you need to update the firmware on it, as I did that and all LoL freezing disappeared.

Don't forget to update your firmware when you use the new SanDisk! Many SSDs are shipped with firmware 3-6 months out of date, causing stuttering and freezing.

Hello, as of the last patch. I am having the same exact issue as you stated above. I don't think it would be my GPU considering it was fairly new and I do not use a solid state drive. All of my drivers are up to date, etc. Was wondering if you found a solution to this problem? It just started occurring after this last patch and only freezes my pc from this game. I also play WoW, so I got on for a few hour w/ maxed video settings and it runs no problem.

My specs:
Processor AMD Phenom(tm) II X6 1090T Processor, 3200 Mhz, 6 Core(s), 6 Logical Processor(s)
System Type x64-based PC
Total Physical Memory 12.0 GB
Total Virtual Memory 24.0 GB
Graphics Chipset: AMD Radeon HD 6900 Series

I replaced my SSD (updated the firmware) and I have experienced the same issue several more times since. I now believe that the cause is running Skype and LoL at the same time. I do not recall running into the problem when Skype was not running.

Bump, looking for an answer, is it really skype.. Because I have the exact same problem and I have been running skype everytime
