Can't figure out crashes, help!

I had bad ram so sent it in. Immediately after it came back, mobo had boot problems. Got that rma today. I installed and booted back into windows, but I have gotten two gray line freezes while web surfing today. It did the same exact lock up when my ram went bad weeks ago when all these problems began. I am testing the ram as we speak, so far no errors. What else could be the problem? The mobo I received back is my same mobo, just with a reflashed BIOS. Is it possible I need to reinstall windows since the mono BIOS did change? I can't figure out what's wrong. This PC is 3 months old and has been such a headache

OCZ SSD as in, Sandforce SSD? Also, put your video card back to stock, until everything else is stable.

Not Sandford. It's 60gb but I don't know which? Agility maybe?

The Agility 2 and 3, at least, are Sandforce (was the 1st a Barefoot?). Make sure its firmware is up to date, at the least.
