System hang with some BSOD

Windows 7 is stalling during general use for around 30 seconds every 10 mins.

There have been about 4-5 BSOD following the stalls.

Windows is on an SSD that is about 4 years old and reports 45% life remaining.

Any help is appreciated.

Windows 7 64
MSI 790FX-GD70
AMD 965BE @ 3400 MHz OC off
XFX4890 x2 crossfire
OCZ vertex SSD 60GB
2x4GB Mushkin 1600 9-9-9-24
XFX 750 PSU

Is the firmware of the SSD up to date?

Please uninstall Daemon Tools. It uses a driver called sptd.sys which is known to cause BSODs in Windows 7.

 SPTD Removal:

• Uninstall the software using Add/Remove Programs.
• Reboot the system.
• Once the program is uninstalled, run sptd.sys uninstaller to remove the driver from your system.
• DuplexSecure - Downloads

As an alternative, many people recommend the use of Total Mounter or Magic ISO

 Clean boot

• Troubleshoot Application Conflicts by Performing a Clean Startup

Reduce items at start-up. No software except anti-virus is required plus doing this improves the time for logging into windows:
