I am recently having constant freezes of my OS. They are random, 30 secs to 1min long, sometimes when I try to open Windows explorer, other times when Chrome tries to access its disk cache or when I am playing a game, it randomly freezes and crashes.
I've upgraded my PSU, mobo and GPU yesterday, after my old mobo died. After setting everything up and booting into windows 8, the freezes started happening.
I've tried to install a fresh copy of Windows 7,but the installation failed each time after windows files have been expanded. In the end I've managed to complete the installation by modifying some registry keys.
The freezes started happening again in Windows 7.
Currently I am running memtest86 to rule out any memory problems. I am at pass 3/4 with no errors so far.
The SSD is a OCZ Vertex 2 120GB (2 years old). I've done read and write tests with Hard Disk Sentinel Pro and no errors or bad sectors showed up.
I've also tried to switch from AHCI to IDE, update to the latest frimware, latest chipset and sata/raid drivers with no luck,. The freezes keep happening.
1.) Download the OCZ PC Bootable Toolbox version 5.4.298 http://ocz.com/consumer/download/firmware
2.) Follow the instructions on the User Guide and install the .iso file to a USB thumb drive or CD/DVD
3.) Boot to the USB or CD and update the firmware on the drive to the latest version 1.37
4.) If the firmware is already on the latest version then Secure Erase the drive. A Secure Erase restores any SSD to a blank, fresh-out-of-the-box condition.
5.) After you have updated the firmware and SE'd the drive do a fresh install of Windows 8. Don't format the SSD in advance, let Windows do it automatically during the install process. Double-check that your SATA port is in AHCI mode before beginning the Windows install.
