Crashing to desktop with error message

This is happening A LOT lately. Every 10 minutes or so I seem to be crashing. I keep getting an error message saying that "the memory could not be read".. I'll attach a pic of it. I downloaded and ran Memtest86 I think it is, and did a full memory test, which passed. My game must have submitted 400 crash logs to LL by now in the last few days. lol

When I first started having this problem, I figured something went wrong with my computer as another of my games was crashing, so I formatted and reinstalled windows. Still having same problem but only in SL now.

I have all the latest drivers to my knowledge and windows updates.

Here are my specs:
ASUS ATI Radeon 9600xt
Gigabyte GA-7n400-L nForce 2 motherboard
AMD 2500+ Barton processor
2x256mb pc2700 Kingston ram dual channel
Sound Blaster Audigy Gamer sound card

As I've read in these forums ATI cards don't play well with Second Life client. I have the EXACT same video card type (same model, diffrent brand) and I don't crash that often.. maybe a couple times in a month.

Get new video drivers from ATI (not ASUS) Also posting error messages like that is really useless and meaningless. Every computer is diffrent so the memory ranges those error messages report would be diffrent from computer to computer. After doing tech support for a short time you realize those messages are totaly useless.

Also the memeory it refers to might be the ram in the video card, not system ram.

I'd also check for viruses, spyware, and try a registry cleaner. If your install of windows is over 6 months old, and you been installing and uninstalling a lot of software in the time, your system probably has tons of "bitrot".

Also if you have a ton of icons sitting in your system try.. kill them. run msconfig and remove those usless programs that don't do anything but take up ram and CPU cycles. I usualy try to keep it under 20 processes/apps running, when you have no apps running.
