Every time in the single player the gaqme crashes in level 1 on the same spot. it says CryEngine error
*** Memory allocation for 2956640 bytes failed *** can anybody help me?

google and download a program called prime 95, run torture test on blend (that will test memory for stability), and see if you get any errors or blue screens. If you do then you have hardware issues with your memory/memory controller whether it be built into the motherboard chipset (like Intel lga 775) or the cpu itself (like Intel nehalem or AMD Phenom II)
