Occasional crashes - Windows 7 64 bit

#1
Occasionally my Windows 7 64 bit system crashes. When it happens the screen goes crazy (filled with black and white static) for several seconds, then it reboots. I haven't noticed any discernable pattern as to triggering events. Any help in troubleshooting this would be greatly appreciated.

I have attached the minidump for the most recent crash.

System specs are as follows:

CPU: Intel core i5 750 2.6 GHz (not overclocked)
Motherboard: Gigabyte P55-UD3
BIOS: F7
Graphics: Sapphire HD5770 1GB
Graphics Driver: 8.671-091026a-090883E-ATI
Catalyst Version: 9.11
Memory: Corsair CMX4GX3M2A1600C9 4GB

Thanks in advance ...

The two most likely causes of a random crash are memory and bad hard drive sectors.

Run a DOS-boot memory scan to check for bad memory (Google for a program to create a bootable ISO) and use Tools under your C-Drive (from My Computer) to run a chkdsk with repair of bad sectors.

Thanks for the reply. I have already checked memory and done a full chkdsk and no errors were found. I'm hoping someone can take a look at the attached minidump as it will hopefully contains some clues as to where the problem lies.

the fact your using a gdr patched windows 7 version suggests as quoted from digitallife
GDR is normally distributed via Windows Update and Microsoft Download Center to improve user experience, and contains software updates that address widespread critical issues, such as security vulnerabilities, and that are broadly released. The fact that Microsoft adds GDR into build string of OS kerner (ntoskrnl.exe) of Windows 7 RTM may signifies that the reliability and stability can still be improved considerably.
without symbols it's hard to get any useful information from debugger but from the little it shows it could be your issue may be any USB device such as external hard drive that you have installed , i suggest remove all external usb devices and monitor for crashes :)

If removing your USBs doesn't fix the problem, use MSCONFIG to remove all 3rd party programs from running at startup and disable all non-Microsoft Services at startup. If you don't crash for awhile, you can try adding them back a few at a time. There are a few programs and services that can interact and crash you. One such combination is ZoneAlarm and Microsoft Security Essentials. That combination was crashing several of my client's installations.

You can do the same thing by running in Safe Mode for awhile but you can't do much there.

Thanks for the advice all. I sometimes have an android-based smartphone connected to the computer via the USB. I wonder if this is a contributing factor. I will keep a record of future crashes and see if they correspond to when the phone is connected.
