Can't press ctrl+v at the same time

[JaredH]

So an issue suddenly happened with my keyboard this morning. All other commands regarding ctrl work apart from ctrl+v.
I've tried re-installing drivers and nothing seems to work. Another issue is when I try to boot the computer up in safe mode, upon reaching the windows repair screen (not sure if it's called that, the one you navigate to all the safe mode option from) the keyboard doesn't work at all.
Also I did try an older keyboard and ctrl+v worked perfectly fine on it.
My keyboard is a Logitech G105
My OS is Windows 7 Home Premium 64-Bit
Oddly enough setting one of my G keys to ctrl+v seems to work, I'm just not actually able to press the two keys at the same time. Screenshot by Lightshot

Jared my first thought is the KB is malfunctioning ? under warranty? but you could try these mate for starters

http://www.sevenforums.com/tutorials/433-disk-check.html < if necessary include the /f and /r in the command line as per Option2
Run these in safe mode and the sfc often best run for two to three runs

Okay I'll try, thanks.

Well. After doing that, it didn't seem to do anything but I did manage to fix it in...A weird way.

So I took the keyboard and plugged it into another computer to see if ctrl+v would work, which it did. I brought it back over to my computer and tried it again and suddenly it's working again. Not sure how or why but it somehow solved itself.

At a rough guess Jared probably dirty USB contacts, however it the issue recurs then it may be the USB fitting on the board .
