My Acer notebook crashed manytimes with BSOD please help.

Recently it was OK. But after windows fail to restart. I restored by using norton ghost. After booting windows, BSOD happen about 4 times (as attached). I don't know what went wrong. But after booting in safe mode, it work fine. I tried to update driver in safe mode, all said updated.

Four different causes in 4 crashes. There are several possibilities.

1-Old drivers

How To Find Drivers:
- search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- visit the web site of the manufacturer of the hardware/program to get the latest drivers (DON'T use Windows Update or the Update driver function of Device Manager).
- if there are difficulties in locating them, post back with questions and someone will try and help you locate the appropriate program.
- - The most common drivers are listed on this page: Driver Reference Driver Reference
- - Driver manufacturer links are on this page: Drivers and Downloads

2- Macaffee. I would remove and replace with Microsoft Security Essentials

How to uninstall or reinstall supported McAfee consumer products using the McAfee Consumer Products Removal tool (MCPR.exe)

Virus, Spyware & Malware Protection | Microsoft Security Essentials

3-Since all 4 point towards memory exceptions I would also run memtest

Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program.

Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

Great advice! I follow step by step. And now problem is gone. My notebook works well now. Thank you very much.
