Windows 7: Keyboard randomly refuses to accept a key or two when game is running

Keyboard randomly refuses to accept a key or two when game is running

Hi,
I have a fairly new (two days?) installation of Windows 7 on a new laptop. Everything here is Genuine etc. It's all working fine, except for...
When Vindictus (a game) is running, the keyboard randomly stops responding for a fraction of a secnd (so for example, the user would notice that random lettrs are missing from the typing).
It's unlikely to be a resource problem (machine is running at like 16% CPU) and the keyboard should be new (HP Envy Laptop btw).

How can I debug this problem? MS Security Essentials is running, but as far as I can tell, the problem occurs even when it's not. I don't believe anything else out of the ordinary is running. Task Manager process list is bloated with loads of random stuff, but I can't imagine where anything malicious could have come in this early in the product's life.
It does not occur on my other laptop, which is virtually identical software-wise, though an older model hardware-wise.

thanks

Edit: I don't know if it's related to games now... seems like it does happen even after booting :/

Edit: It even happens in safe mode.
I guess I need to find another keyboard to test with or something.

Edit: Uncertain, but seems to be resolved by changing power settings to full performance. Could have been a side effect of the CPU needing to re-clock itself due to programs requiring resources, then releasing them? (Min/Max CPU state thing)
