Daily BSOD on cold boots & random freezes

I have an ASUS n80vn laptop that is about 3 years old. It came with OEM Windows Vista, but I installed my own copy of Windows 7 Professional 64bit more than two years ago, and there was no problem upon installation.

Lately (for about a month), I have been receiving BSOD either during boot or the log-in screen. The BSOD usually happens only once per day, and I would be forced to restart my computer. No BSOD upon restart. I suspect the problem occurs when the laptop is cold. I have attached the BSOD Dump files collected over the past month.

The only driver change I've had was nVidia graphic driver updates. I've uninstalled and reinstalled the two most recent drivers and the BSOD problem still occurs.

On a side note, I have been getting random freeze-ups too, and this has been happening before the BSOD problem. These freezes occur when I'm doing regular tasks such as web browsing or typing in Word/Excel etc. When my system freezes, there is no BSOD, but nothing can be moved (keyboard + mouse won't do anything). Closing lid does nothing too. Strangely, I have not been getting this kind of freezes when I play games.

I am having a hard time pinpointing the source of the problems. Any assistance is much appreciated.

Quick rundown of specs:
-Windows 7 Professional 64bit (retail)
-Age of hardware: ~3 years
-Age of OS: ~2
-Processor: Intel core duo P8600 2.40 GHz
-RAM: 4GB
-GPU: GeForce 9650m GT

I have switched protection programs to MSE and Windows 7 Firewall.

The BSOD problem persists.

Old drivers should be update, uninstall any Vista drivers
