Scan the system for possible virus infection.
Test your RAM modules for possible errors. Run memtest for at least 8 passes, preferably overnight.
Run SFC /SCANNOW Command - System File Checker

. Use Microsoft Security Essentials
as your antivirus with windows inbuilt firewall, and free MBAM
as the on demand scanner.
Run chkdsk /f/r, following the option two
of the tutorial Disk Check
If, after doing all these the crashes continue to occur, enable Driver Verifier to monitor the drivers. Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.
Let us know the results, with the subsequent crash dumps, if any.
