Download that zip and burn the image file, it will create a bootable cd. Then run memtest to test your memory.
In addition, you can try installing your ram into another machine and use it for a while to see if you can get it to lock up.
Before going and buying any hardware, first thing I would do is back up all your important files. Then do a clean install of windows, if the problem persists; then I would suspect a hardware problem ie: bad ram or failing hard drive.
90% of the time shit is fixed by an annual/semi-annual clean installation of windows.
Oh yeah, see if there are any bios/software updates for your motherboard by going to sony's website.
good luck.
