Beeping Sound + Lag?

I have an Antec 1200 case with 6 fans, and the problem only started with Windows 7.

I'm pretty sure I'm hitting some keystroke for something if I can simply make it stop by standing still and tapping shift.

Do you have adequate cooling? Run SpeedFan to find out.

With Vista, I didn't have this problem, so it's not the hardware I think it's directx 11.. Since I installed it, I've been having these problems..

Found a fix!!

The problem is with CTRL + Space switching between languages.
Go to the control panel, remove any extra languages and disable any shortcut keys. This fixed the problem for me, GL HF!

Hi Everyone

I seem to have this same issue...

This happens every time I play games, doesn't matter what game I play... Even though this didn't happen when I built the PC.

Windows 7 Ultimate x64
Intel i5 4670k
120gb Sandisk Extreme ssd
Intel mobo
Sapphire Radeon 7770HD Of Edition

I checked speedfan and there's no overheating issues at all. I've been using a USB Mac keyboard for more than 3 years now. This seem to have started around 4 months ago.

While I play games, I can hear a fairly soft beep and the keyboard button I pressed, is w for forward, would get "stuck" and the character would keep moving in that direction. Doesn't matter what I do, nothing can stop this. This stays like this for a few seconds, then for some reason the game looks like it freezes for a split second as if its loading. Once this is done, the character still moves in that same direction but if I press the same button again, it stops and I can continue playing. This would happen around 5 times every minute.

I'm sure you can see that its damn annoying. I've tried the above and one seems to work.

Please can anyone help here?
