Random Shutdowns/Crashes throughout day

Logs - View attachment 67742 - I've had this Alienware laptop for about a year now, and it started to crash at random intervals throughout the day around 3 months ago. It runs windows 8.1 and works perfectly (other then the crashes). When it crashes it does not give me a BSOD, but rather just goes to the colored 'Shutting down' screen before shutting down. I've been running it in Safe Mode with networking and it doesn't seem to crash during that, so I don't think it's hardware. I ran the log collector program in Safe Mode with networking, I hope that doesn't mess with anything. Thanks.

Update: I recently uninstalled the NVIDIA driver after reading another thread with the Display Driver Uninstaller program. It seems that the crashes have stopped! But now I face the problem of not being able to use my NVIDIA graphics card, I can only use the not-so-good integrated intel card. What should I do? Are there NVIDIA drivers that won't crash my laptop?

Did you use the drivers from your motherboard or the generic Nvdia driver.
With a laptop it is adviced to use the "customized" OEM drivers from your manufactorer
