Guys, have any of you encountered a peculiar occurrence with a Logitech G15v2?

Each time when I would play a game, be it Counter-Strike or RAGE, a specific key would be somewhat pressed down until I've to either restart or log off my account. It tends to happen in the midst of a gaming session. If I'm not launching any games, it wouldn't occur.

Before I reformatted my PC, the key would be C. After reformatting, it would be the Backspace key. Its downright annoying and puzzles me. I've updated the drivers but the problem isn't backing down. I noticed that when I logged in back after logging out, the failed driver installation message, "|-|-|-|-|-|-|-|-SATA(or bearing something similar" would appear.

I've checked on Google, but results aren't same as mine.

Highly probably that its the keyboard at fault, but why does it happen? Anyone could care to enlighten me?
