Nope, I had 2 Gb RAM now, but I play the 0.7 and above with 1 Gb for a long time without any incidents... ( I upgrade my RAM, buying new 2 Gb card, and give my old 1 Gb DDR2 for my friend) no problem... even with my old 1 Gb RAM that now lies on another computer...

Maybe you should check your power supply... It damages components if it has over/underpotential. Maybe some virus coupled with evil spyware... duplicate your process entirely... crippling out your RAM...
EB is slow, but it was safe...
