A few weeks ago my computer started crashing, BSOD, memory dump the whole nine yards. Alternately, it would hang and/or crash while gaming.

My first thought was to check temps, which were fine, albeit more "summery." I run my q9550 at 4.0 24/7, but I also use the speed step feature to save whatever energy it can. This set-up is months-on folding stable.

Just for kicks, I disabled the speed step and associated features, and it still crashed. I backed off on my CPU/RAM OC and left the voltages alone. It still crashed.

Framerates in Crysis went from very decent (even on very high) to completely unplayable with artifacting, hanging and crashing. In fact, all the crashed had happened while playing Crysis. Most game levels were fine, so I assumed my install had gotten corrupted, so I re-installed it. Virtually all of my problems happened in the late (ship-board) levels or when that big spider thing was around.

All my temps were fine, or were as fine as I could determine.

Now I've had my 4870 crash before because of an unstable OC (it doesn't like to be overclocked ) and the Catalyst rescue feature has been very good at saving the crash and re-establishing stability. Today, I finally got around to under-clocking the graphics processor and the memory, just a little. It's like beer again.

So I now have a smokin' overclock on my HD4850 but I can play my games without unnecessary stress.
