A few months ago my computer started crashing when playing games. The screen would turn either black, white, (or once pink), the fan/fans would max out, and the audio would just change to a loud buzzing sound. This would continue until the laptop was turned off. Around that time, one of my hard drives was failing. We thought, seeing as it fitted so well, that it was the problem. I've just had the hard drives replaced, and while it was running perfectly for a few days, it has now started to crash again, and far more frequently. Most of the time just after the desktop loads. I'm currently running in safe mode, and that's perfectly fine. No crashing. I've tried disabling my audio drivers, and rolling back my video card driver, but with no success. I'm assuming that as safe mode has no problems that it must relate to a driver, or, some software, but I have no real clue what I'm talking about. My video card is the NVIDIA GeForce GTX 580M, if that's important. No idea what other information to include. Thanks for any help anyone can give me.
