Grey screen of death (sometimes), odd behavior

[racuerex]

Hey guys, I'm (seemingly out of nowhere) getting a grey screen of death on my system. It has been working for a few months, and now it cant stay on for more than 30 mins without freezing (sometimes grey screen, sometimes not), or me opening something that may trigger a grey screen. It seems to be mostly Chrome/Gmail/google that are triggers (all google tabs in chrome seem to be the first go Aw, Snap! on me), but even safari one out of 20 times won't do something right and crashes...and sometimes it just and then I need to restart.

One of the times I got this screen (only seen it once so far):



The spotlight was acting weird, so I turned off indexing - I use it a lot, that is why it was on. TRIM is enabled, other than that everything WAS working fine for months.

At first after reading I thought it might be the SSD (cause it seemed like bad ram/ssd behavior) so I flashed the SSD FW, switched the ram sticks over to different ports and orders. No go, same behavior so far.

So I'm writing this on the machine right now, everything seems to be working fine for now. I'm running the following hardware:

Mountain Lion 10.8.2
Core i7-3770K (no OC)
Gigabyte Z77-UD5H (latest FW)
EVGA GTX570 1.25GB
Corsair Vengeance 16GB DDR3 1600mhz
Sandisk Extreme 240GB (latest FW)
2x 2TB 7200RPM Seagate in a mirror raid set
Sony optiarc DVDRW
Seasonic 850W GOLD PSU


Any ideas? Thanks for the help in advance! This has me

Also to add to this, when the system freezes (it's not always a GSoD), everything continues to work, the graphical interface freezes, if I have radio playing, it'll keep going (for hours) until I do a hard off. Does that mean video card? I'd imagine if it were the SSD, it'd stop completely...unless things are running from the ram...

is there a way to run a diagnostic on it and post it here to see what is wrong? I ran disk until, fixed permissions, flashed everything to the latest firmware, haven't redone multibeast since I haven't changed anything, and my plists are good to go.
